Vitamin D Receptor and Megalin Gene Polymorphisms and Their Association With Obesity, Central Obesity and the Metabolic Syndrome

National Institute on Aging (NIA)·observational·Posted Sep 12, 2017·Updated Sep 12, 2017

In Brief

An observational study for Metabolic Syndrome and 2 related conditions. Completed, enrolled 1,021 participants.

Detailed Summary

The link between metabolic disturbances and vitamin D receptor (VDR) and MEGALIN (or LRP2) gene polymorphisms remains unclear, particularly among African-American adults. The associations of single nucleotide polymorphisms (SNPs) for VDR \[rs1544410(BsmI:G/A), rs7975232(ApaI:A/C), rs731236(TaqI:G/A)\] and MEGALIN \[rs3755166:G/A,rs2075252:C/T, rs2228171:C/T\] genes with incident and prevalent metabolic disturbances, including obesity, central obesity and metabolic syndrome (MetS) were evaluated. From 1,024 African-Americans participating in the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS, Baltimore, MD, 2004-2013) study, 539 subjects were selected who had complete genetic data as well as covariates selected for metabolic outcomes at two consecutive examinations (visits 1 and 2) with a mean follow-up time of 4.64±0.93y. Haplotype (HAP) analyses generated polymorphism groups that were linked to incident and prevalent metabolic disturbances.
