Genome-wide significant predictors of metabolites in the one-carbon metabolism pathway. [PMID 19744961] G allele associated with lower serum Vitamin B12. "The TCN1 rs526934 G variant may reduce transport of cobalamin, resulting in lower plasma vitamin B12 levels."
[PMID 27901035] This large study (over 50,000 people) found no evidence for "positive association of homocysteine or negative associations of folate and vitamin B12 with CAD/MI".
