Abstract
Methionine loading tests and folate, vitamin B(6), and vitamin B(12) analyses were performed in 27 mothers of children with congenital heart defects. Median fasting plasma homocysteine concentrations were significantly higher in the study group as compared with 56 control subjects (P =.0001). Maternal hyperhomocysteinemia may be a risk factor for congenital heart defects.
