CDH13 Genetic Polymorphisms, Adiponectin and Ischemic Stroke： a Chinese Family-based Sib-pair Study

Objective To understand the relationships between CDH13（T-cadherin） genetic polymorphisms, adiponectin levels and ischemic stroke, and possible interactions between CDH13 polymorphisms and other risk factors. Methods We recruited 342 Chinese ischemic stroke sib pairs. We genotyped rs4783244 and rs71...

Description
Summary:	Objective To understand the relationships between CDH13（T-cadherin） genetic polymorphisms, adiponectin levels and ischemic stroke, and possible interactions between CDH13 polymorphisms and other risk factors. Methods We recruited 342 Chinese ischemic stroke sib pairs. We genotyped rs4783244 and rs7193788 on CDH13 using time-of-flight mass spectrometry genotyping technology and measured total and high-molecular weight（HMW） adiponectin levels. We investigated associations between SNPs and ischemic stroke, and interactions between SNPs and other risk factors using multi-level mixed-effects regression model. Results In individuals without ischemic stroke, CDH13 rs4783244 was associated with total adiponectin levels（per T： Coef =-0.257, P = 0.001）. CDH13 rs7193788 was associated with total adiponectin levels（per A： Coef =-0.221, P = 0.001） and HMW adiponectin levels（per A： Coef =-0.163, P = 0.003）. rs7193788 was significantly associated with ischemic stroke（GA/AA vs. GG： OR = 1.55, 95% CI： 1.07 to 2.24, P = 0.020） after Bonferroni correction（α = 0.025）. There was an interaction between rs7193788 and diabetes（P = 0.036）. Compared to diabetes-free individuals with rs7193788 GG genotype, diabetes patients with rs7193788 GA/AA genotypes had higher risks for ischemic stroke（OR = 2.64, 95% CI： 1.58-4.40, P 〈 0.001）. Conclusion CDH13 genetic polymorphisms are associated with adiponectin levels and ischemic stroke. An interaction is found between CDH13 SNP and diabetes for ischemic stroke.
