Identification of new genetic polymorphisms that alter the dietary requirement for choline and vary in their distribution across ethnic and racial groups

This observational study examined how genetic polymorphisms impact dietary choline requirements and their prevalence across different ethnic and racial groups. Researchers analyzed 200 SNPs in 10 choline metabolism-related genes among 79 individuals on a low-choline diet. The study found that specific SNPs, such as PEMT rs12325817, increased the risk of
