3 Billion pairs of DNA define a human. Small changes in DNA are called SNPS.
Only 6-9 Million SNPS is all that is differentiates the DNA of 6.7 Billion people on Earth.
Today, genetic companies report on ~10% of known SNPS for the savvy consumer.
The saliva is processed, DNA extracted and then replicated.
DNA is analyzed by SNP chips, looking key variations called markers.
Thats me, as I submit my own DNA as saliva. I also submitted a dozen close relatives.
Markers give you your Relative Risk to the average population.
Average Population Risk for a disease. This value is somewhat subjective.
Your LifeTime Risk =
Relative Risk * Average Population Risk
From Saliva to SNPs to your
LifeTime Risk
of Disease
