Polymorphisms in adiponectin receptor genes are associated with lipodystrophy-related phenotypes in HIV-infected patients receiving antiretroviral therapy.

Abstract

Adiponectin is a circulating peptide secreted by mature adipocytes that may act as a regulator of glucose and lipid metabolism. This study aimed to investigate the association between genetic variability in the adiponectin receptor genes ADIPOR1 (adiponectin receptor 1) and ADIPOR2 and lipodystrophy and its related anthropometric and metabolic phenotypes in HIV-infected patients on highly active antiretroviral therapy (HAART). We studied six single nucleotide polymorphisms (SNPs) in the adiponectin receptor genes ADIPOR1 (rs1342387 and rs10920533) and ADIPOR2 (rs11061925, rs10773983, rs929434 and rs767870) and their association with adiponectin plasma levels, lipodystrophy subtypes and other parameters linked to glucose and lipid metabolism involved in the lipodystrophic syndrome. The genotypes of 407 HIV-infected patients receiving HAART were investigated using real-time polymerase chain reaction. Mean biochemical and anthropometrical parameters were compared between the different genotypes using analysis of variance. Two ADIPOR2 SNPs (rs11061925 and rs929434) were associated with fasting plasma triglyceride concentrations in the entire sample. Stronger significant associations were found between these SNPs and biochemical parameters (levels of triglycerides, total cholesterol, adiponectin and glucose) in men. We did not find any significant associations with ADIPOR1 gene variants. SNPs in the ADIPOR2 gene appear to be involved in the metabolic alterations in HIV-infected men receiving HAART.
