Genome hacking philosophy July 19, 2011 DIYgenomics.org
Goal: preventive medicine
Realize preventive medicine by establishing baseline markers of wellness and pre-clinical interventions
Generalized hypothesis
One or more polymorphisms may result in out-of-bounds baseline levels of phenotypic markers. These levels may be improved through personalized intervention.

Vitamin B deficiency / MTHFR mutation
Do common mutations in the MTHFR gene prevent vitamin B from working correctly?
Test whether 2 variations in the MTHFR gene 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 of cardiovascular disease, etc.)
50% or more of the population may have some form of MTHFR polymorphism

Health hackers need Blood Tests 2.0
Low-cost home-administered self-read finger-stick blood, urine, saliva tests:
Traditional blood tests (Homocysteine, Vitamin B-12, Folate, Vitamin D, Creatinine, eGFR, Cortisol, Calcium, Iron, Aldosterone)
Hormones (Estrogen, Progesterone, Testosterone, Estradiol)
Immune system: CD4, CD8/CD28 ratio, IL-1, IL-6
Chemical / h eavy metal burden: mercury, cadmium, lead, tin

Towards an epistemology of citizen science
Provide a structure and context for self-derived health knowledge
Q1: Are new kinds of knowledge are being formed through group collaborations such as wikipedia and health social networks?
Q2: Are there differences in the types of knowledge generated by traditional medicine, self-experimentation, and health collaboration communities?
