title: [Association between calpain-10 gene polymorphism and risk of type 2 diabetes mellitus: a meta analysis].
abstract: 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).
  
  
  CONCLUSIONS
  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.
