We identified a strong association (P = 5.36 x 10(-17)) between rs492602 in FUT2
and plasma vitamin B(12) 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 B(12) levels. This allele is in
strong linkage disequilibrium with the FUT2 nonsecretor variant encoding W143X,
suggesting a plausible mechanism for altered B(12) absorption and plasma levels.
