Maternal vitamin D receptor genetic variation contributes to infant birthweight among black mothers.

ABSTRACT: Racial disparity in pregnancy outcomes is one of the most striking and poorly understood inequalities in American health. Genetic variability may be an important host factor influencing disparate birth outcomes between non-Hispanic black (NHB) and non-Hispanic white (NHW) women. Race-specific allelic frequencies in the vitamin D receptor (VDR) gene suggest its potential as a gene involved in health disparities. The Healthy Pregnancy, Healthy Baby Study is a prospective cohort of pregnant women aimed at identifying genetic, social, and environmental contributors to disparities in pregnancy outcomes in Durham, NC. VDR haplotype tagging single nucleotide polymorphisms (SNPs) were genotyped via Taqman assays for 615 women. Analysis of variance was used to examine the association between matern
