Genetic Variants at the rs4720169 Locus of and the rs12921862 Locus of May Increase the Risk of Congenital Heart Defects in the Mexican Population: A Pilot Study.

Congenital heart defects (CHDs) are the most common type of birth defects and a major cause of infant mortality. Although knowledge of genetic risk variants for CHDs is scarce, most cases of CHDs are considered to be due to multifactorial inheritance. To analyze the association of 14 single nucleotide polymorphic variants previously associated with a risk of CHDs in a Mexican population with isolated CHDs.
