Abstract

Adiponectin is associated with obesity and insulin resistance. Several genome-wide association studies of adiponectin levels have identified candidate genes, including the CDH13 gene. The study objective was to examine the association of serum adiponectin levels (or hypoadiponectinemia) with SNP rs4783244 in CDH13 gene considering fasting blood glucose levels. This study included 2,005 subjects. Hypoadiponectinemia was defined as the lowest quartile of adiponectin. The CDH13 gene SNPs were genotyped via the TaqMan reaction. The multivariate linear regression models and multiple logistic regression analysis were performed. The majority of individuals were middle-aged. Subjects with the GG genotype had a 2.44-fold (range 1.97–3.03-fold) higher risk of hypoadiponectinemia than subjects with the TG/TT genotype. When analyzed by fasting blood glucose levels, the CDH13 association was much stronger in male subjects with pre-diabetes (odds ratio, 10.96; 95% confidence interval, 4.31–27.88; P < 0.0001). Our results suggested that the association between CDH13 and adiponectin can be modified by fasting blood glucose levels.
