摘  要:目的探讨钙蛋白酶10(CAPN10)基因SNP43、SNP44位点及主要单倍型、单倍型组合与2型糖尿病(T2DM)的关联性。方法根据系统评价的原理和规范,检索PubMed及中文期刊数据库,纳入CAPN10基因与T2DM的病例对照研究。根据种族,采用分层Meta分析评估CAPNIO基因多态性与T2DM的关联性。同时评估发表偏倚。结果各种族与T2DM有关联的基因多态性分别是:蒙古人种,SNP43位点G等位基因OR=1.368(95%CI:1.155~1.620),G/G基因型OR=1.437(95%CI:1.186—1.741),111/221单倍型组合017=2.762(95%CI:1.287—5.927);高加索人种,SNP44位点C等位基因OR=1.144(95%CI:1.023—1.278),111/111单倍型组合OR=1.291(95%CI:1.050-1.586);混血人种,SNP44位点C等位基因OR=1.653(95%CI:1.025—2.665)。结论SNP43位点G等位基因、G/G基因型、111/221单倍型组合是蒙古人种的危险因素;SNP44位点C等位基因、111/111单倍型组合是高加索人种的危险因素;SNP44位点C等位基因是混血人种的危险因素。Objective The purpose of this study was to approach the relation of SNP43, SNP44 locus, main haplotypes and haplotype combinations with type 2 diabetes mellitus (T2DM). Methods According to the theory and principles of systematic review, data from case-control studies regarding the association between calpain-10 (CAPN10) gene and T2DM were derived through electronic search of PubMed and Chinese journals databases. To gain a more precise estimation of the relationship, a stratified Meta-analysis with four subgroups was performed according to the races. Publication bias was also assessed, Results The association with T2DM in different races was evaluated, In Mongoloid race, SNP43-G allele, G/G genotype and 111/221 haplotype combination showed notable association with T2DM with ORs(95%CI)as 1.368(1.155-1.620), 1.437 ( 1.186-1.741 ) and 2.762 (1.287-5.927) respectively. In Caucasoid race, SNP44-C allele, 111 / 111 hapotype combination showed strong relationship with T2DM with ORs(95%CI)as 1.144 (1.023-1.278) , 1.291 (1.050-1.586) respectively. In Hybrid race, only one positive finding was obtained which was SNP44-C allele with OR (95% CI) as 1.653 (1.025-2.665). Conclusion SNP43-G allele, G/G genotype, 111/221 were risk factors to Mongoloid race. And SNP-C allele, 111/ 111 haplotype combination were risk factors to Caucasoid race, and SNP44-C allele to Hybrid race.
