Purpose: Metabolic syndrome (MetS) and testosterone deficiency (TD) are two closely linked diseases commonly found among aging men. Insulin resistance is postulated to be an important link between the two. Because hepatocyte nuclear factor 4 alpha (HNF4A) can regulate gene expression and insulin secretion in pancreatic β cells, single-nucleotide polymorphisms (SNPs) of HNF4A may increase the risk of both MetS and TD in men. Therefore, we investigated the relationship between SNPs of HNF4A and the risk of developing MetS and TD in a population of aging Taiwanese men.
Materials and Methods: A health screening of men over 40 years of age was conducted free of charge by a medical center in Kaohsiung City, Taiwan. All participants received a physical examination, answered a questionnaire, and provided a 20 cc sample of whole blood for purposes of biochemical and genetic evaluation. Serum albumin, total testosterone (TT), and sex hormone-binding globulin levels were measured. Free testosterone level was calculated. Three common SNPs (rs11574736, rs1884613, and rs2144908) of HNF4A were selected and identified using a TaqMan 5’ allelic discrimination assay
Results: A total of five hundred and fifty-nine men were enrolled for this study (mean age: 55.8±4.9 years). Prevalence of TD was significantly higher (p=0.031) in subjects with MetS (16.8%) than those without MetS (10.1%). In SNP rs1884613 of HNF4A, subjects with the C allele carried a 1.31 and 1.50 times higher risk of developing MetS and TD, respectively, compared to those with the G allele, after adjusting for potential covariates. In addition, subjects with the CC genotype were exposed to a 1.91 and 2.20 times higher risk of developing MetS and TD, respectively, compared to those with the GG genotype.
Conclusion: The rs1884613 SNP marker of HNF4A may be significantly associated with an increased risk for developing both MetS and TD in aging Taiwanese men. Our findings may point to the importance of the role played by insulin resistance in the link between MetS and TD. Further population-based studies utilizing larger samples of different ethnicities may be needed to confirm these preliminary results.
