Methods The method of PCR- RFLP was conducted to examine the genotype of 3 cPLA2 genes ( PLA2G4A, PLA2G4B and PLA2G4C genes) in 263 subjects, including 121 cases of T2DM and 142 controls. The conditional test was used to test the combined effect of distinct loci on the T2DM by conditioning on allele or by conditioning on genotype with UNPHASED analysis platform. Results The genotypic frequencies of the 3 genes did not deviate from Hardy-weinberg equilibrium in both case and control groups.

采用聚合酶链反应-限制性内切酶片段长度多态性方法检测T2DM患者（病例组121例）和健康对照（对照组142例）3个cPLA2基因（PLA2G4A、PLA2G4B和PLA2G4C基因）的基因型；借助UNPHASED分析平台，利用等位基因条件分析和基因型条件分析方法分析基因的联合作用与T2DM的遗传相关性。
