Aims/Introduction: Genetic risk variants for type 2 diabetes; rs391300-G in SRR and rs17584499-T in PTPRD, have been identified by a genome-wide association study using Han Chinese individuals living in Taiwan. In an attempt to know the effects of these two variants in conferring susceptibility to type 2 diabetes in the Japanese, we carried out a replication study for the association of the two single nucleotide polymorphisms (SNPs) with type 2 diabetes in a Japanese population. Materials and Methods: We genotyped 11,530 Japanese individuals (8,552 type 2 diabetes patients and 2,978 controls) for rs391300 and rs17584499, and analyzed the association of these two SNPs with type 2 diabetes by logistic regression analysis. Results: Neither of the variants was associated with susceptibility to type 2 diabetes in the Japanese population (rs391300-G: odds ratio [OR] = 0.97; 95% confidence interval [CI] 0.91-1.04; P = 0.44; rs17584499-T: OR = 1.04; 95% CI 0.96-1.14; P = 0.34). Adjustment or stratified analysis for age, sex and body mass index (BMI) did not affect the association of these variants with the disease. We did not observe a significant association of the SNPs with any metabolic traits, BMI, fasting plasma glucose, homeostasis model assessment of β-cell function (HOMA-β) and HOMA of insulin resistance (HOMA-IR) (P > 0.05). Conclusions: Neither rs391300 nor rs17584499 had a significant effect on conferring susceptibility to type 2 diabetes in the Japanese population.
