Prevalence of trisomy 21 following folic acid food fortification

14 Apr 2003

Abstract excerpt

Polymorphisms of maternal genes responsible for normal folate metabolism may be associated with an increased risk of fetal trisomy 21. By January 1998, most of Canada's flour was being fortified with folic acid. We investigated whether the prevalence of antenatally and postnatally detected trisomy 21 changed before and after folic acid food fortification. A total of 218,977 women underwent second trimester...
