CNV Annotations: a crucial step in your variant analysis
Since the development of our NGS-based CNV solutions for VarSeq and SVS, we've generated a long list of content demonstrating simple workflows to help isolate clinically relevant events for a given sample. However, it's just as important to talk about the exclusionary filters that help remove any extraneous CNVs from the analysis.
Golden Helix stands alone in our delivery of multiple methods for filtering down to top-quality, rare, and clinically relevant variants. This webcast will focus on the application of the various CNV annotations, discussing their purpose and usability in quickly removing CNVs with high-population frequency, duplicated regions inherent to the human genome, benign events, and events known in healthy individuals.
Please join us in an exploration of VarSeq's unique CNV annotation capabilities to see how users can overcome the challenges of NGS-based CNV detection.
What will you learn in this webcast?

We also cover the types and effective utilization of annotations in VarSeq. Finally, he covers how users can create their own annotation sources from the Convert Wizard tool.
Evaluating Oncogenicity in VSClinical
Before assessing the clinical significance of a somatic mutation, one must determine if the mutation is likely to be a driver mutation (i.e. a mutation that provides a selective growth advantage, thereby promoting cancer development). To aid clinicians in this process, VSClinical provides an oncogenicity scoring system, which uses a variety of metrics to classify a given somatic mutation into one of the following categories: oncogenic, likely oncogenic, benign, likely benign, or uncertain significance. This scoring system is heavily inspired by the ACMG Guidelines for the interpretation of germline mutations but has several important differences to make it more applicable in the context of somatic variant interpretation.
Our oncogenicity scoring system relies on an additive point system in which points are assigned to a given variant based on several criteria. Many of the criteria are shared by the ACMG Guidelines for germline variant interpretation, such as population frequency information, variant effect on protein function, and nearby pathogenic variants in catalogs such as ClinVar. However, other criteria are specific to the world of somatic variant interpretation. These include the variant’s presence in somatic catalogs such as COSMIC, the effect of other known oncogenic variants in the same gene, and the variant’s presence in known cancer hotspots or active binding sites. These criteria are combined by summing over the scores for all applicable scoring criteria. Scores exceeding 3 indicate an oncogenic or likely oncogenic classification, while scores falling below -3 indicate a benign or likely benign classification.
In this webcast, we discuss how each of these scoring criteria are combined to obtain an oncogenicity classification. This includes a discussion of the considerations taken into account during the development of this scoring system and a detailed analysis of several example mutations to illustrate the system in practice.

Additionally, we will also investigate the clinical section of the ACMG guideline tool to see how to leverage the inheritance and allelic state of each variant. After this webcast, the user will discover new avenues of examining trio data by utilizing the ACMG classifier to improve upon one of our classic templates.
Whole Genome Trait Association in SVS
Golden Helix’s SNP & Variation Suite (SVS) has been used by researchers around the world to do trait analysis and association testing on large cohorts of samples in both humans and other species. As Next-Generation Sequencing of whole genomes becomes more affordable, large cohorts of Whole Genome Sequencing (WGS) samples are available to search for additional trait association signals that were not found in array-based testing. In fact, recent papers have shown that WGS analysis using advanced GREML (Genomic Relatedness Restricted Maximum Likelihood) techniques is able to outperform micro-array based GWAS methods in the analysis of complex traits and proportion of the trait heritability explained.
Our latest update release of SVS has expanded the exiting maximum likelihood and GRM methods to support these new techniques. We have also enhanced various other association testing and prediction methodologies. This webcast showcases:
- Newly supported analysis workflow for whole genome variants using LD binning and enhanced GBLUP analysis
- Enhanced gender correction using REML
- Additional capabilities for genomic prediction and phenotype prediction
We are continually improving our products based on our customer’s feedback. We hope you enjoy this recording highlighting the exciting new features and select enhancements we have made.
Using Golden Helix CancerKB to Accelerate NGS Cancer Testing
Next Generation Sequencing is being rapidly integrated into the oncology field. From the clinical perspective, both somatic and germline NGS results are informative for hereditary cancer risk and treatment strategies. There are numerous scattered resources that inform the clinical significance of a somatic mutation for a patient’s tumor type. Similarly, there are many FDA-approved anti-cancer agents and drugs with changing indications, and opportunities for off-label use. Even more, there are clinical trials all over the world that though they require specific genetic alterations for enrollment eligibility, they could provide more treatment options for cancer patients.
What’s the bottom line? It is certainly a huge undertaking to evaluate a gene or biomarker’s role in cancer or clinical significance. It requires sifting through trials that are relevant for the patient from the abundance of literature available, not to mention staying well-informed on new research as it is published.
Golden Helix CancerKB offers a solution. We demonstrate the application of CancerKB and how easy somatic variant analysis can be in VSClinical. Namely, I will deep dive into the following topics:
The process our expert curators use to produce high-quality cancer interpretations
Examples of complex biomarker interpretations simplified using CancerKB
Report content filled in by CancerKB, even for rare genes
Integrating customer feedback and the future of CancerKB
Advanced VSClinical Reports with Scripting and Custom Integrations
Golden Helix VSClinical provides a guided workflow interface for following the ACMG and AMP guidelines for the evaluation of variants and CNVs for NGS tests. The output of this work is most often a lab-specific clinical report. Since VSClinical was introduced, we have provided a powerful Word-based templating system that allows labs to customize reports to include their specific content and branding.
Although powerful, this capability has been limited to customizing the contents of a Word file. Sometimes, the next logical step for the VSClinical analysis result is not a Word file, but some other file or target system: A database, LIMS, EMR, or even just a custom structured text file.
Join us in this webinar, as we discuss the next version of VarSeq, which will introduce a powerful scripting and custom integration engine built into VSClinical Reports. We will cover:
Capabilities and outputs of the workflows of VSClinical ACMG and Cancer
Content of VSClinical reports, including sample-QC, coverage statistics, custom gene panels, and data providence
The shipped report templates that range from gene panels to exome trios and comprehensive cancer testing
The new custom script-based reports and example workflows it enables
The tools enabling a powerful developer experience when building custom outputs and integrations
The VarSeq Suite holds customization and extendibility as core values, allowing the powerful capabilities of variant analysis to be truly customized to the needs of a specific laboratory and NGS test. The new scripting and integration capabilities build on this tradition for the VSClinical workflows. We hope you can join us as we explore this topic in-depth in this webinar.
Exploring New Features and Clinical Reports in the ACMG Guideline Workflow
For the past year, Golden Helix has been preparing a VarSeq release that includes ACMG Guidelines scoring and classification for not only single nucleotide variants but also copy number variants. In the past few months, our webcasts have introduced these guidelines and explored example CNVs that demonstrated the automated scoring of CNVs according to the new ACMG CNV Guidelines. However, there are many other new features and upgrades that have been incorporated into this VarSeq release. These upgrades have largely been driven by input from VarSeq users! That’s why I am very excited to explore these features together in the upcoming webcast “Exploring New Features and Clinical Reports in the ACMG Guideline Workflow”. In this webcast, we will walk through a workflow with SNVs and CNVs highlighting many of the new features and upgrades that will improve and streamline your ACMG workflow. Notably, we will see how these new features can also be incorporated into clinical reports.
Specifically, we will cover the following features:

Reduce Turn-Around with Enhanced Cancer Annotations and CancerKB Updates
Annotation sources are constantly evolving, sometimes quite literally overnight. This is especially true in the case of cancer databases. These ever-evolving annotation sources, coupled with increasing research publications, make it difficult to do variant analysis with up-to-date scientific knowledge. With the resources available to an individual clinician or single lab, this may even prove impossible. Fortunately, VSClinical provides access to the most current clinical annotation sources - automating scoring and interpreting variants according to the most recent ACMP and AMPO guidelines. This includes many fast-changing sources such as ClinVar and COSMIC, as well as expert-curated reviews of literature and the latest drug-labeling from regulatory bodies.
In this webcast, we demonstrate the automation of a cancer workflow with enhanced cancer annotations for somatic and germline cancer variants:
- Golden Helix’s own CancerKB database has been updated to include new interpretations for genes and biomarkers with AMP Tier Level I evidence for drug sensitivity, resistance, diagnostic, and prognostic information.
- We feature a new Golden Helix curated annotation source that automates the scoring of TP53 variants with the special rule specifications by ClinGen’s TP53 Expert Panel.
- The ClinGen Expert Curated Interpretation of Variants has always been available as an annotation source for VarSeq projects, but now the expert comments and interpretations can automatically be pulled into VSClinical and used for clinical reports.
This webcast walks through a hematological-focused cancer workflow that shows off the enhanced cancer annotations and CancerKB updates!
VSWarehouse: Tracking Changing Variant Evidence and Classifications
Over the years, VarSeq has evolved into a powerfully efficient next-gen sequencing variant analysis platform. Some of the recent advances Golden Helix has made to this software have been to implement the standard ACMG and AMP guidelines for variant classification and interpretation. The guidelines are composed of many criteria impacting any variant final classification. These criteria consider topics such as frequency of the variant among the population, functional predictions, hotspot pathogenic rich regions in the gene, as well as known clinical submissions from other labs. The reality with this guideline review is that variant evidence can changeover time. Among the long list of databases needed to automate this guideline process, many databases have massive updates or are frequently updated perhaps on a month-to-month basis. So, it follows that any classification can be altered once discoveries for these variants are made. A problem that arises is, how to manage changing classifications, retroactively review previous patient outcomes and updatevariant classifications accordingly. Fortunately, Golden Helix has solved this dilemma with the use of our VSWarehouse genomic repository.
In this webcast, we are going to explore the value and application of VSWarehouse. Our example variants will showcase a situation where variants of uncertain significance ultimately reach a pathogenic classification based on updates to ClinVar. This change will be presented not only in VarSeq with listings of previous samples but also shown directly from the VSWarehouse browser in a ClinVar classification tracker. We will also look at an alternative situation where the classification may change to benign for some previously reported variants which would require follow-up with the patient. The importance of a tool like the ClinVar tracker in VSWarehouse cannot be understated as it is a simple way to comprehensively review the backlog of changing variant classifications when users must update their locked down validated NGS pipeline. Please join us in the upcoming webcast to explore how these features in VarSeq and VSWarehouse work to allow users thorough accountability in updating historical patient results with new variant evidence
Evaluating Copy Number Variants with VSClinical's New ACMG Guideline Workflow
Golden Helix has been in close communication with the publishers of the ACMG guidelines and the ClinGen group to receive expert advice on how to interpret CNVs called on NGS data. These guidelines provide a robust set of rules for interpreting intragenic deletions and duplications, which is summarized into an intricate decision tree that is broken down into 80 distinct criteria. This complexity is further compounded by many important caveats, exceptions, and considerations known to many in the CNV clinical workspace but are not mentioned in the published guidelines. Fortunately, Golden Helix has spent long hours reading the guidelines, watching the webinars, reading the supplementary material, and working with collaborators to develop a comprehensive workflow to guide you through your clinical interpretation of CNVs. Herein, we are excited to cover more details into this novel ACMG CNV guideline interpretation workflow and demonstrate how intuitive this feature can be for your clinical pipeline. Specifically, we will cover:
The intricacies of the ACMG CNV Sample auto classifier
Unique annotations and algorithms
Adjustable metrics and parameters in the VSClinical ACMG interface

VSClinical: a complete clinical workflow solution
Clinical variant analysis involves many steps and potentially requires the expertise and input from multiple individuals. For many, this process can be rather complex as it entails moving the data from user to user and possibly multiple platforms or internal bioinformatic pipelines. In general, this workflow can be broken down into three stages:
- Quality control (QC) and processing of the data. This step involves importing the data into a tertiary analysis platform and validating that the variants and samples are high quality.
- Variant evaluation using different genomic databases and annotation sources, which is then incorporated into a draft report.
- Assessment and assurance that the previous steps were performed correctly and a sign-off on the report.
Golden Helix offers VSClinical, a complete clinical workflow solution that simplifies and streamlines the clinical analysis process outlined above. VSClinical is a single testing paradigm that consolidates and automates the tertiary analysis workflow. With this software, users can perform variant and sample QC, create a variant evaluation using a plethora of public and licensed annotation sources and evaluate variants with the automated ACMG and AMP guidelines for SNVs, Indels, and CNVs. All this information can then be used to create a clinical report with our new word-based report templates.
In this webcast, we plan to demonstrate the full clinical analysis workflow within VSClinical, focusing on the topics below:
- How easy it is to perform the different stages of a tertiary analysis in VarSeq and VSClinical
- The fluidity in transferring data between different users
- Evaluating germline and somatic variants according to the ACMG and AMP guidelines
- Creating and signing off on a clinical report with the new word-based templates
Building Secure Analysis and Storage Systems with Golden Helix
Genetic testing labs deal with personal data in categories with the highest level of security requirements: personal identity and medical records. Given the liability and risk associated with a breach of this secure information, it is not surprising that many labs and institutes that aggregate genomic data prefer if not require on-premise analysis and storage solutions.

Evaluating Oncogenicity in VSClinical
Before assessing the clinical significance of a somatic mutation, one must determine if the mutation is likely to be a driver mutation (i.e. a mutation that provides a selective growth advantage, thereby promoting cancer development). To aid clinicians in this process, VSClinical provides an oncogenicity scoring system, which uses a variety of metrics to classify a given somatic mutation into one of the following categories: oncogenic, likely oncogenic, benign, likely benign, or uncertain significance. This scoring system is heavily inspired by the ACMG Guidelines for the interpretation of germline mutations but has several important differences to make it more applicable in the context of somatic variant interpretation.
Our oncogenicity scoring system relies on an additive point system in which points are assigned to a given variant based on several criteria. Many of the criteria are shared by the ACMG Guidelines for germline variant interpretation, such as population frequency information, variant effect on protein function, and nearby pathogenic variants in catalogs such as ClinVar. However, other criteria are specific to the world of somatic variant interpretation. These include the variant’s presence in somatic catalogs such as COSMIC, the effect of other known oncogenic variants in the same gene, and the variant’s presence in known cancer hotspots or active binding sites. These criteria are combined by summing over the scores for all applicable scoring criteria. Scores exceeding 3 indicate an oncogenic or likely oncogenic classification, while scores falling below -3 indicate a benign or likely benign classification.
In this webcast, we discuss how each of these scoring criteria are combined to obtain an oncogenicity classification. This includes a discussion of the considerations taken into account during the development of this scoring system and a detailed analysis of several example mutations to illustrate the system in practice.

Using Golden Helix CancerKB to Accelerate NGS Cancer Testing
Next Generation Sequencing is being rapidly integrated into the oncology field. From the clinical perspective, both somatic and germline NGS results are informative for hereditary cancer risk and treatment strategies. There are numerous scattered resources that inform the clinical significance of a somatic mutation for a patient’s tumor type. Similarly, there are many FDA-approved anti-cancer agents and drugs with changing indications, and opportunities for off-label use. Even more, there are clinical trials all over the world that though they require specific genetic alterations for enrollment eligibility, they could provide more treatment options for cancer patients.
What’s the bottom line? It is certainly a huge undertaking to evaluate a gene or biomarker’s role in cancer or clinical significance. It requires sifting through trials that are relevant for the patient from the abundance of literature available, not to mention staying well-informed on new research as it is published.
Golden Helix CancerKB offers a solution. We demonstrate the application of CancerKB and how easy somatic variant analysis can be in VSClinical. Namely, I will deep dive into the following topics:
The process our expert curators use to produce high-quality cancer interpretations
Examples of complex biomarker interpretations simplified using CancerKB

Advanced VSClinical Reports with Scripting and Custom Integrations
Golden Helix VSClinical provides a guided workflow interface for following the ACMG and AMP guidelines for the evaluation of variants and CNVs for NGS tests. The output of this work is most often a lab-specific clinical report. Since VSClinical was introduced, we have provided a powerful Word-based templating system that allows labs to customize reports to include their specific content and branding.
Although powerful, this capability has been limited to customizing the contents of a Word file. Sometimes, the next logical step for the VSClinical analysis result is not a Word file, but some other file or target system: A database, LIMS, EMR, or even just a custom structured text file.
Join us in this webinar, as we discuss the next version of VarSeq, which will introduce a powerful scripting and custom integration engine built into VSClinical Reports. We will cover:
Capabilities and outputs of the workflows of VSClinical ACMG and Cancer
Content of VSClinical reports, including sample-QC, coverage statistics, custom gene panels, and data providence
The shipped report templates that range from gene panels to exome trios and comprehensive cancer testing
The new custom script-based reports and example workflows it enables
The tools enabling a powerful developer experience when building custom outputs and integrations
The VarSeq Suite holds customization and extendibility as core values, allowing the powerful capabilities of variant analysis to be truly customized to the needs of a specific laboratory and NGS test. The new scripting and integration capabilities build on this tradition for the VSClinical workflows. We hope you can join us as we explore this topic in-depth in this webinar.

Reduce Turn-Around with Enhanced Cancer Annotations and CancerKB Updates
Annotation sources are constantly evolving, sometimes quite literally overnight. This is especially true in the case of cancer databases. These ever-evolving annotation sources, coupled with increasing research publications, make it difficult to do variant analysis with up-to-date scientific knowledge. With the resources available to an individual clinician or single lab, this may even prove impossible. Fortunately, VSClinical provides access to the most current clinical annotation sources - automating scoring and interpreting variants according to the most recent ACMP and AMPO guidelines. This includes many fast-changing sources such as ClinVar and COSMIC, as well as expert-curated reviews of literature and the latest drug-labeling from regulatory bodies.
In this webcast, we demonstrate the automation of a cancer workflow with enhanced cancer annotations for somatic and germline cancer variants:
- Golden Helix’s own CancerKB database has been updated to include new interpretations for genes and biomarkers with AMP Tier Level I evidence for drug sensitivity, resistance, diagnostic, and prognostic information.
- We feature a new Golden Helix curated annotation source that automates the scoring of TP53 variants with the special rule specifications by ClinGen’s TP53 Expert Panel.
- The ClinGen Expert Curated Interpretation of Variants has always been available as an annotation source for VarSeq projects, but now the expert comments and interpretations can automatically be pulled into VSClinical and used for clinical reports.
This webcast walks through a hematological-focused cancer workflow that shows off the enhanced cancer annotations and CancerKB updates!
VSWarehouse: Tracking Changing Variant Evidence and Classifications
Over the years, VarSeq has evolved into a powerfully efficient next-gen sequencing variant analysis platform. Some of the recent advances Golden Helix has made to this software have been to implement the standard ACMG and AMP guidelines for variant classification and interpretation. The guidelines are composed of many criteria impacting any variant final classification. These criteria consider topics such as frequency of the variant among the population, functional predictions, hotspot pathogenic rich regions in the gene, as well as known clinical submissions from other labs. The reality with this guideline review is that variant evidence can changeover time. Among the long list of databases needed to automate this guideline process, many databases have massive updates or are frequently updated perhaps on a month-to-month basis. So, it follows that any classification can be altered once discoveries for these variants are made. A problem that arises is, how to manage changing classifications, retroactively review previous patient outcomes and updatevariant classifications accordingly. Fortunately, Golden Helix has solved this dilemma with the use of our VSWarehouse genomic repository.
In this webcast, we are going to explore the value and application of VSWarehouse. Our example variants will showcase a situation where variants of uncertain significance ultimately reach a pathogenic classification based on updates to ClinVar. This change will be presented not only in VarSeq with listings of previous samples but also shown directly from the VSWarehouse browser in a ClinVar classification tracker. We will also look at an alternative situation where the classification may change to benign for some previously reported variants which would require follow-up with the patient. The importance of a tool like the ClinVar tracker in VSWarehouse cannot be understated as it is a simple way to comprehensively review the backlog of changing variant classifications when users must update their locked down validated NGS pipeline. Please join us in the upcoming webcast to explore how these features in VarSeq and VSWarehouse work to allow users thorough accountability in updating historical patient results with new variant evidence
Evaluating Copy Number Variants with VSClinical's New ACMG Guideline Workflow
Golden Helix has been in close communication with the publishers of the ACMG guidelines and the ClinGen group to receive expert advice on how to interpret CNVs called on NGS data. These guidelines provide a robust set of rules for interpreting intragenic deletions and duplications, which is summarized into an intricate decision tree that is broken down into 80 distinct criteria. This complexity is further compounded by many important caveats, exceptions, and considerations known to many in the CNV clinical workspace but are not mentioned in the published guidelines. Fortunately, Golden Helix has spent long hours reading the guidelines, watching the webinars, reading the supplementary material, and working with collaborators to develop a comprehensive workflow to guide you through your clinical interpretation of CNVs. Herein, we are excited to cover more details into this novel ACMG CNV guideline interpretation workflow and demonstrate how intuitive this feature can be for your clinical pipeline. Specifically, we will cover:
The intricacies of the ACMG CNV Sample auto classifier
Unique annotations and algorithms
Adjustable metrics and parameters in the VSClinical ACMG interface

VSClinical: a complete clinical workflow solution
Clinical variant analysis involves many steps and potentially requires the expertise and input from multiple individuals. For many, this process can be rather complex as it entails moving the data from user to user and possibly multiple platforms or internal bioinformatic pipelines. In general, this workflow can be broken down into three stages:
- Quality control (QC) and processing of the data. This step involves importing the data into a tertiary analysis platform and validating that the variants and samples are high quality.
- Variant evaluation using different genomic databases and annotation sources, which is then incorporated into a draft report.
- Assessment and assurance that the previous steps were performed correctly and a sign-off on the report.
Golden Helix offers VSClinical, a complete clinical workflow solution that simplifies and streamlines the clinical analysis process outlined above. VSClinical is a single testing paradigm that consolidates and automates the tertiary analysis workflow. With this software, users can perform variant and sample QC, create a variant evaluation using a plethora of public and licensed annotation sources and evaluate variants with the automated ACMG and AMP guidelines for SNVs, Indels, and CNVs. All this information can then be used to create a clinical report with our new word-based report templates.
In this webcast, we plan to demonstrate the full clinical analysis workflow within VSClinical, focusing on the topics below:
- How easy it is to perform the different stages of a tertiary analysis in VarSeq and VSClinical
- The fluidity in transferring data between different users
- Evaluating germline and somatic variants according to the ACMG and AMP guidelines
- Creating and signing off on a clinical report with the new word-based templates
Building Secure Analysis and Storage Systems with Golden Helix
Genetic testing labs deal with personal data in categories with the highest level of security requirements: personal identity and medical records. Given the liability and risk associated with a breach of this secure information, it is not surprising that many labs and institutes that aggregate genomic data prefer if not require on-premise analysis and storage solutions.
Golden Helix is in a unique position to provide completely on-premise analysis solutions with a history of building analysis software from the ground-up on first principles and a focus on providing integrated, turn-key solutions. This allows for a licensing model based on training and supporting users, not tracking per-sample usage of cloud resources.

Analyzing Performance of the Twist Exome with CNV Backbone at Various Probe D...
Clinical Whole Exome Sequencing (WES) offers a high diagnostic yield test by detecting pathogenic variants in all coding genes of the human genome. WES is poised to consolidate multiple genetic tests by accurately identifying Copy Number Variation (CNV) events, typically necessitating microarray analyses. However, standard commercial exome kits are limited to targeting exon coding regions, leaving significant gaps in coverage between genes which could hinder comprehensive CNV detection.
Addressing the need for comprehensive coverage, Twist Bioscience has developed an enhanced Twist Exome 2.0 Plus Comprehensive Exome Spike-in capture panel with added "backbone" probes. These probes target common SNPs polymorphic in multiple populations and are evenly distributed in the intergenic and intronic regions, with three varying densities at 25kb, 50kb, and 100kb intervals. In this webcast, we discuss the combined efficacy of the backbone-probe enhanced exome capture kit and VS-CNV in identifying known CNVs using the Coriell CNVPANEL01 reference set.
This webcast reviews:
-The sensitivity rate for the detection of known CNV events at all three probe densities.
-The impact of best-practice quality metrics and filters on sensitivity.
-How VarSeq’s CNV annotation capabilities can be leveraged to identify likely pathogenic CNVs.
-The interpretation of clinically relevant CNVs using VSClinical.

VarSeq 2.5.0: Empowering Family Planning through Carrier Screening Analysis
Over the past 50 years, partners with potential genetic risks have sought advanced genetic testing to guide family planning decisions. Carrier screening is a valuable tool in genetics and reproductive medicine that helps individuals and families make informed choices about family planning and reduce the risk of passing autosomal recessive or X-linked genetic disorders to their children. Several carrier screening panels are available for Next-Generation Sequencing platforms, ranging from those targeting prevalent disorders to expanded ones covering various inherited conditions. Since NGS offers an affordable, high-throughput solution, carrier screening has become a common practice in healthcare systems.
We are excited to announce that VarSeq and VSClinical now support a multi-sample carrier screening workflow. VarSeq 2.5.0 unlocks the ability to:
-Filter variants between samples and identify genes in which a variant from each partner sample is present.
-Apply the ACMG Carrier Screening gene panel or generate customized carrier screening panels to include in your analysis.
-Evaluate partnered samples side-by-side in a single VSClinical evaluation.
-Generate a combined sample clinical report that includes reproductive risk calculations for the most prevalent autosomal recessive and X-linked diseases.
Identifying Oncogenic Variants in VarSeq
The interpretation of somatic variants can be a challenging process. While AMP Guidelines provide detailed rules for accessing the clinical evidence associated with a specific variation, they do not specify criteria for determining if a variant is likely to be a driver mutation, which generates functional changes that enhance tumor cell proliferation. In this webcast, we will discuss a new VarSeq algorithm for estimating the oncogenicity of a variant. This will include a deep dive into our oncogenicity scoring system and a discussion of the various criteria used to distinguish driver mutations from benign variations and variants of uncertain significance.
What you will learn in this webcast:
-How to use the scoring algorithm to identify variants with evidence of oncogenicity
-Which criteria are used to assess a variant's oncogenicity
-How to evaluate the oncogenicity of a variant in VSClinical

The Wide Spectrum of Next-Generation Sequencing Assays with VarSeq
There is a strong motivation for labs to bring most, if not all, of their next-gen sequencing pipeline in-house. This is especially relevant for clinical applications where there is a need to validate any routine diagnostics when seeking to provide genetic results to patients. The entirety of the NGS pipeline is highly automatable and comprised of multiple stages but from the geneticist's point of view, the tertiary stage requires the lengthiest review. This stage is where the geneticist sifts through the massive collection of genetic variants to find and report on those most relevant to the patient or population. Unfortunately, the tertiary stage can be a fairly sophisticated process and there aren’t many tools on the market that handle it comprehensively and simply. Many of the tools that are available may have severe limitations on the scale of genomic data they can process or limitations on the types of NGS assays that can be designed. Moreover, their license model may be on an individual sample basis and present cost-benefit hurdles for the user, especially when sample load will inevitably increase. Fortunately, none of these assay or cost-based issues are relevant with Golden Helix products.
The goal of this webcast is to expose our viewers to the versatility that GHI VarSeq provides when constructing your dream NGS assay. This demonstration will provide examples of germline and somatic workflows for both single and multi-sample analysis for a variety of different disorders. Please join us and learn more about the analytical possibilities you can achieve when using the VarSeq software.
Prenatal Genetic Screening with VarSeq
Our past webcast explored the current approaches for screening and diagnosis of genetic disorders in prenatal testing. While the methods available at the time were robust, they were severely limited, creating a need for a higher diagnostic yield and more efficient analysis for a wider range of genetic tests. The solution proposed was to improve and simplify prenatal screening and diagnosis with whole exome sequencing (WES).
During that webcast, we highlighted the advantages of WES over traditional methods such as karyotyping and chromosomal microarray, including improved accuracy, granularity, and cost-effectiveness. We also emphasized the potential of WES to expand diagnosis for many other adverse maternal-fetal complications beyond the large aneuploidy events previously covered. However, there was still an intimidation factor when it came to the massive data output from the exome. Fortunately, Golden Helix provided the necessary tools to build and standardize these genetic assays, simplifying the analytical process while leveraging increased diagnostic output. We explored our VarSeq software to demonstrate some example workflows of cases positive for Trisomy 21, an exon loss in DMD related to Duchenne Muscular Dystrophy, and detection of a single base change resulting in a LOF variant in RUNX1 relevant to hereditary leukemia.
Our goal was to expose our viewers to the methods of conquering this vast NGS-based data and play a role in dissolving any feeling of intimidation. Overall, exome sequencing has the potential to vastly improve diagnostic outcomes and widen discoveries in the research related to prenatal testing, and Golden Helix products are designed to facilitate this process.

For anyone from grizzled VarSeq veterans to those seeing our software for the first time and labs of any size, we will provide a practical overview of our somatic analysis capabilities and how those capabilities scale with improving technology.
Throughout this webcast we will be discussing the following:
- Universal principles of somatic workflows, providing baseline recommendations
- Specific tumor-normal and somatic-only use cases
- VSClinical AMP interpretation hub and some variants of interest
- Opportunities for automation and how to decrease time to report for increased throughput
Join us as we show off the versatility and scalability of our AMP interpretation capabilities!
Maximizing Profitability in your NGS Testing Lab
The automation of clinical NGS workflows provides a number of important benefits for labs. Automation reduces the time required to produce a clinical report, mitigates the possibility of human error, and improves the precision of clinical results. In turn, these benefits create higher profitability from a P&L perspective.
Golden Helix software is designed to meet these needs by automating the full analysis workflow from sequencer to clinical report on a fixed annual subscription model. We are looking forward to discussing the best practices of maximizing profitability in your NGS testing lab and how Golden Helix supports these efforts.
Join us in this webinar as we cover how to develop repeatable cancer and germline interpretation workflows that scale from panels to whole exomes and genomes.
Handling a Variety of CNV Caller Inputs with VarSeq
VarSeq has become renowned for the accuracy of its CNV Caller, and the ease with which VSClinical takes the user through CNV evaluation. Cited in many publications, this well-validated tool brings our customers the ability to run both variant and CNV interpretations in one program, on data ranging from Gene Panels to whole genomes. What is less well known about CNV analysis through VarSeq, is that our users are not only limited to CNVs called through our software. VarSeq CNV is able to import CNVs in several file formats (VCFs, text, or tsv) generated by a wide variety of secondary callers, allowing the user to analyze their externally derived data. In this webcast, we will take you through the basics of CNV analysis with both the VarSeq CNV caller and from several common external CNV callers.
Join us in this webinar as we cover:
Leveraging the Copy Number Probability and Segregation Algorithm to add power to a CNV Trio workflow.
Importing externally called CNVs.
Expediting the path to analysis with CNV specific templates.
Utilizing the auto-recommendations to efficiently analyze the pathogenicity of several CNV calls and generate clinical reports.
VarSeq Custom Database Curation Capabilities.pdf
As our users have come to know, VarSeq serves as a hub for variant annotation and the full interpretation/classification of germline (ACMG) and somatic (AMP) variants. Whether direct annotation or backend variant evidence is being presented to the user via VSClinical for the interpretation process, users greatly benefit from the hosted variant databases being available directly from VarSeq. Our team has automated much of the curation process and hosts the ongoing updates to these tracks so that users no longer suffer manual review of each database via the web or manual curation efforts. Useful databases include ClinVar and ClinGen for classification submissions, gnomAD exomes/genomes for filtering out common variants in the population, RefSeq for gene impact and sequence ontology assessment, and OMIM for phenotypic information. Obviously, there is a large collection of databases out there, and not all of them make it into our automated queue. However, GHI supports the utilization of custom databases in our software. This webcast will expose features of custom database curation/utilization in VarSeq to optimize your NGS workflows even further.
During the presentation, we will discuss many different approaches with custom annotations, including:
Interval Tracks: Bed files defining target regions for coverage calculations and CNV detection.
Assessment catalogs: record keeping of variant classification/interpretations in VSClinical.
Frequency catalogs: approaches to capture all variant allele frequencies at a project level and cohort level with VSWarehouse.

BOWEL ELIMINATION BY ANUSHRI SRIVASTAVA.pptx
Defecation
Normal defecation begins with movement in the left colon, moving stool toward the anus. When stool reaches the rectum, the distention causes relaxation of the internal sphincter and an awareness of the need to defecate. At the time of defecation, the external sphincter relaxes, and abdominal muscles contract, increasing intrarectal pressure and forcing the stool out
The Valsalva maneuver exerts pressure to expel faeces through a voluntary contraction of the abdominal muscles while maintaining forced expiration against a closed airway. Patients with cardiovascular disease, glaucoma, increased intracranial pressure, or a new surgical wound are at greater risk for cardiac dysrhythmias and elevated blood pressure with the Valsalva maneuver and need to avoid straining to pass the stool.
Normal defecation is painless, resulting in passage of soft, formed stool
CONSTIPATION
Constipation is a symptom, not a disease. Improper diet, reduced fluid intake, lack of exercise, and certain medications can cause constipation. For example, patients receiving opiates for pain after surgery often require a stool softener or laxative to prevent constipation. The signs of constipation include infrequent bowel movements (less than every 3 days), difficulty passing stools, excessive straining, inability to defecate at will, and hard feaces
IMPACTION
Fecal impaction results from unrelieved constipation. It is a collection of hardened feces wedged in the rectum that a person cannot expel. In cases of severe impaction the mass extends up into the sigmoid colon.
DIARRHEA
Diarrhea is an increase in the number of stools and the passage of liquid, unformed feces. It is associated with disorders affecting digestion, absorption, and secretion in the GI tract. Intestinal contents pass through the small and large intestine too quickly to allow for the usual absorption of fluid and nutrients. Irritation within the colon results in increased mucus secretion. As a result, feces become watery, and the patient is unable to control the urge to defecate. Normally an anal bag is safe and effective in long-term treatment of patients with fecal incontinence at home, in hospice, or in the hospital. Fecal incontinence is expensive and a potentially dangerous condition in terms of contamination and risk of skin ulceration
HEMORRHOIDS
Hemorrhoids are dilated, engorged veins in the lining of the rectum. They are either external or internal.
FLATULENCE
As gas accumulates in the lumen of the intestines, the bowel wall stretches and distends (flatulence). It is a common cause of abdominal fullness, pain, and cramping. Normally intestinal gas escapes through the mouth (belching) or the anus (passing of flatus)
FECAL INCONTINENCE
Fecal incontinence is the inability to control passage of feces and gas from the anus. Incontinence harms a patient’s body image
