Common variants of FUT2 are associated with plasma vitamin B12 levels

Abstract

We identified a strong association (P = 5.36 × 10−17) between rs492602 in FUT2 and plasma vitamin B12 levels in a genome-wide scan (n = 1,658) and an independent replication sample (n = 1,059) from the Nurses' Health Study. Women homozygous for the rs492602[G] allele had higher B12 levels. This allele is in strong linkage disequilibrium with the FUT2 nonsecretor variant encoding W143X, suggesting a plausible mechanism for altered B12 absorption and plasma levels.
