Fast Caffeine Metabolizer. Unlike the majority of people, caffeine is broken down faster in your liver, so it has less effect on you. Supposedly this decreases heart attack risk, although other studies show caffeine is generally good for the heart. Caffeine will be less effective at preventing Breast Cancer, Alzheimer's Disease, and Parkinson's disease. Caffeine will not make your breasts smaller.
rs762551, also known as -164A>C or -163C>A, is a SNP encoding the CYP1A2*1F allele of the CYP1A2 gene. For historic reasons, the rs762551(C) allele is considered the wild-type, even though it is the rarer allele in most populations. The rs762551(A) allele is the 'fast metabolizer' allele known as CYP1A2*1F; the (C) allele is by comparison a slower metabolizer of certain substrates (including caffeine). In terms of genotypes, only rs762551(A;A) individuals are considered fast metabolizers. Individuals who are rs762551(A;C) heterozygotes or rs762551(C;C) homozygotes are both considered slow metabolizers. The CYP1A2 gene encodes a member of the cytochrome p450 family of proteins, which metabolize nutrients and drugs
