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
PharmGKB, dbSNP, GWAS catalog, SNPedia

DIYgenomics study #1: MTHFR
Do common mutations in the MTHFR gene prevent vitamin B from working correctly?
Test whether 2 variations in the MTHFR gene (methylenetetrahydrofolate reductase) keep vitamin B9 (folic acid) from being metabolized into its active form (folate)
rs1801133/C677T
rs1801131/A1298C
Without this form of vitamin B, homocysteine may accumulate
Risk: nutritional deficiencies and symptoms associated with diabetes complications, including vascular damage and nerve damage
50% or more of the population may have some form of MTHFR polymorphism
