  • 37. WE CAN BE EMBARRASSED WHEN WE DON’T KNOW…
  • 38. • Genetic disorders are rare • There are >7000 of them • Genetic and metabolic disease is not well taught in medical school and post-graduate training programs • Genetic awareness is better in pediatrics than in adult medicine WHY ARE GENETIC DIAGNOSES MISSED?
  • 39. • A controversial diagnosis or one that is not easily proven • A variation of a known/provable diagnosis • Think the controversy around “Lyme disease” A “CLINICAL DIAGNOSIS”
  • 40. • ”A neurological disorder caused by a non-progressive brain injury or malformation that occurs while the child’s brain is under development.” (cerebralpalsy.org) • A one-time injury to the brain  static lesion • This is more a description, less a diagnosis • We see the symptoms that derive from this (which may sometimes suggest progression) CEREBRAL PALSY

  • 42. OTHER “CLINICAL” DIAGNOSES • Multiple sclerosis • Charcot-Marie-Tooth disease • Sudden infant death syndrome (SIDS) • And others….
  • 43. • It can explain the patient’s pathophysiology  increases options for (symptomatic) therapy • It can help with care coordination and management • It can introduce opportunities for patient/family support WHY MAKE A “CLINICAL” DIAGNOSIS?
  • 44. BUT… • It can inhibit thinking about the patient’s diagnosis  loss of a real diagnosis (and possible therapy) • It can make patients/families vulnerable to allegations of medical child abuse WHY MAKE A “CLINICAL” DIAGNOSIS?
  • 45. What about when the families get testing on their own? 45
  • 46. DIRECT-TO-CONSUMER (DTC) GENETIC TESTING • Advertised to the public • Individuals order and receive results directly from the company • Mail in cheek swab or saliva sample • Typically use SNP array to detect common SNPs in subset of genes • No requirement for health professional results interpretation or pre-test counseling 46

  • 67. • Found to carry two rare pathogenic intronic variants in CFTR (cystic fibrosis gene) • Subsequent sweat test was positive! 67 RESULTS
  • 68. • CFTR could explain his infertility, gastrointestinal complaints, thyroid disease, and diabetes • May not explain everything but gave him a treatment plan • The rare CFTR variants would not have been picked up on cystic fibrosis screening, and he did not have significant lung disease! 68 COUNSELING

Editor's Notes

  1. PF
  2. Kasey??
  3. PF
  4. I am going to talk a little about what happens when the families get testing on their own. More and more, I get calls from primary care providers seeking advice about the results of genetic testing that their patients are worried about.
  5. This is what we call direct to consumer genetic testing. It is advertised directly to the public, initiated by the consumer or individual without any involvement of a medical or genetics professional and the results are sent directly back to the individual. The science for many is that they use a SNP array to detect common SNPS. What this means from a genetics point of view is that many only test for the most common variants in a gene. And there is often no requirement for pre or post test counseling, although many of the sites do offer link for telephone counseling.
  6. This is the current 23 and ME site. The FDA lifted a previous ban and they are now able to provide some health information as well as ancestry, mostly for carrier status
  7. Here is one of their sample reports. Testing for a variant that has an association with late-onset Alzheimers disease. Seems harmless, right?
  8. The American Board of Internal Medicine began an initiative called Choosing Wisely in order to promote conversations between clinicians and patients by helping patients choose care that is: Supported by evidence Not duplicative of other tests or procedures already received Free from harm Truly necessary Beginning in 2012, national organizations representing medical specialists have asked their members to identify tests or procedures commonly used in their field whose necessity should be questioned and discussed. This call to action has resulted in specialty-specific lists of  “Things Providers and Patients Should Question.” This is the list from the American College of Medical Geneticists
  9. You can see that APOE testing is on that list of don’ts. Their reasoning is that it is not an accurate predictor of Alzheimer disease.
  10. So let’s talk about a case. This is a 25 year old male that has a number of medical complaints none of which fit into a particular condition. He decides to send his DNA into 23 and Me to get some answers.
  11. This is a portion of his results. He sees that he has a “Variant Present” for Phenylketonuria or PKU. He becomes concerned and goes to the internet and thinks this could be his answer. He has always avoided meat and he thinks this might be due to having PKU.
  12. He talks to his primary care provider who orders a phenylalanine level and it is read as elevated. Now let me take a moment here to say that, although his level is out of the range of normal, it is below the level at which we would normally do any treatment. He calls genetics for a genetic counseling appointment.
  13. The genetic counselor calls 23 and Me and asks what the report means, Specifically, since PKU is a recessive condition, did they find one or two variants and what sort of variants did they find. The genetic counselor was told that 23 and Me could not make any diagnostic conclusions in medical conditions, and therefore did not report out how many variants were found. The genetic counselor decided that the best thing to do was to retest him in a clinical laboratory and he was found to have one pathogenic variant or mutation and was therefore a carrier. His symptoms were not due to PKU nor did he need treatment. This whole process was timely, expensive and caused a lot of anxiety in this young man.
  14. It is cases like this that caused the Medical Ethics experts to write an article like this in BMC Medical Ethics article from 2018 that addressed persuasive communication in DTC services.
  15. So, the diagnostic journey can be long for many individuals and this is frustrating. I wanted to point out a few facts about this journey as pertains to genetic testing
  16. Let’s look at another case of a lifelong diagnostic odyssey
  17. His endocrinologist when working him up for his autoimmune thyroiditis, decided to send MTHFR testing. He was found to be positive for two known pathogenic variants
  18. He had also read about mitochondria and energy levels
  19. So what is MTHFR? The MTHFR gene codes for a regulator in folate metabolism and therefore has a natural connection with nutrition in the form of folate supplementation. However, the variants are so common that research has failed to find a direct connection between these variants and true disease.
  20. This title may suggest that there is a connection with autoimmune thyroiditis, but if you read the conclusion, you realize that these pathogenic variants are extremely common in the general population.
  21. The ACMG has come out with a statement against testing for MTHFR. They addressed specifically the evaluation for thrombophilia because of the biochemical relationship with homocysteine.
  22. However, this gene has been advertised as being connected with all sorts of ailments. This is one of the promoters of unsupported theories is the DTC testing of variant in the MTHFR gene
  23. However, the hype goes on. MTHFR variants, according to the internet, can even determine whether your child should be immunized.
  24. So lets’ go back to the case. Due to the infertility, a karyotype was done to rule out Klinefelter that was normal
  25. The results of the comprehensive carrier panel was a surprise. He in fact had two mutations in the CFTR gene – however, they were intronic – meaning not in the coding sequences. He had a sweat test that was positive – confirming that he did in fact have CF.
  26. While there may be symptoms that could not be explained by his CF, it certainly would explain his infertility, GI complaints, and endocrine disorders
  27. His MTHFR is not felt to have any relevance to his complaints.
  28. Finally, I am going to try to give some assistance with how and when to make a referral to a genetic or metabolic specialist.
  29. There are some acute or urgent referrals. If you have appositive newborn screen for SMA, SCID or Pompe, the baby needs to be seen ass soon as possible. This might include other specialists as well as geneticists, depending upon the condition.
  30. In certain metabolic disorders, the referral is not only acute, but may be emergent. The child should be evaluated clinically immediately, and then a plan made for further testing
  31. When you have a child that has some unusual features, developmental delay, autism or frequent illness or other unexplained symptoms, a non-urgent referral to genetic or metabolic clinic might be in order. We would urge you to be suspicious when things just don’t fit. Try to characterize the symptoms as much as possible as far as duration, timing, body systems involved, etc. Collecting any past information will be helpful and we encourage you to reach out to ask questions of the metabolic or genetic specialist before referring.
  32. These are some suggestions of helpful information for genetic and metabolic consultations. I will break this down for clarity..
  33. For both genetic and metabolic consultations, it is helpful to clearly state the clinical question or chief complaint. What is it that is most worrisome to you? Family history is very important. If you do not have an extensive family history recorded, let the family know that they will need to ask family members for that information. Medical history is also very important. Sending records of any previous metabolic or genetic testing is really important, Not only is it times-taking to repeat tests, but insurance often does not cover repeat genetic testing.
  34. If your consult is primarily metabolic in nature, there additional clues are important pieces of information to forward on.
  35. If you suspect a non-metabolic genetic cause, really providing as much about the phenotype as possible is helpful. These include… Again remind the family that it is helpful for them to know as much about their family history as possible.
  36. In some cases, the consult will be more effective if some preliminary testing is done prior to the genetic visit. One of those cases is a referral for a genetic cause of short stature. It is very helpful to
  37. There are resources to let practitioners know about what their patients should expect at a genetics or metabolic clinic visit as well as the information that is helpful to provide. The New England regional genetics network provides both a pdf of a brochure as well as a soon to be posted video covering these topics. The pdf can be found at the website address listed below. In addition, the Weitzman Institute has brochures about their econsult service that also provide a list of indications for referral that can be helpful
