Profiling placental and fetal DNA methylation in human neural tube defects

Abstract excerpt

BACKGROUND: The incidence of neural tube defects (NTDs) declined by about 40 % in Canada with the introduction of a national folic acid (FA) fortification program. Despite the fact that few Canadians currently exhibit folate deficiency, NTDs are still the second most common congenital abnormality.
