Why risk interpretation can vary by consumer genomic service
Companies are using different…
Average lifetime risks for the same underlying population
SNP/loci selection criteria
Quantitative risk assignment methodologies

3. Differences in risk assignment methodology
Relative risk assignment per SNP
Debate: include only strong-effect markers
Composite risk assignment per condition

Agenda

Early sequencing technology
Sanger sequencing (chain termination)
Make millions of different-length copies
Print on electrophoresis gel
Read lengths small to large
Fluorescent indicators denote bases
Reassemble small segments with shotgun sequencing
DIYgenomics.org Sources: http://www.phgfoundation.org/tutorials/dna/5.html, http://www.genomicseducation.ca/files/images/information_articles/sequencing.gif

Contemporary (2 nd -gen) sequencing technology
Illumina Solexa, ABI SOLiD, 454
Illumina example
Attach adaptors to short sequences
Amplify by growing clusters
Add nucleotides, primers
Activate a laser to read bases as incorporated
Assemble clusters simultaneously
Improved read time
Two gigabases/day at $0.001 per 1000 bases vs. Sanger sequencing (one year at $0.10 per 1000 bases)
Hiseq (Jan 2010): 25 gigabases/day

Agenda

Example: what to do with your data
Check if you have the risk allele for the BDNF gene
Determine related SNP/rsID#, rs6265 (neuroplasticity)
Search genomic data for rs6265 genotype (e.g., CC)
Determine the risk allele (which letter?) (e.g.; G 1 )
Opportunity: genomic database with three minimal fields: gene, rsid# and risk allele
Current genomics search resources
