Abstract/OtherAbstract:
Many studies have investigated the association between Glutathione S-Transferase M1 (GSTM1) null genotype and risk of diabetes mellitus, but the impact of GSTM1 null genotype on diabetes mellitus is unclear owing to the obvious inconsistence among those studies. This study aimed to quantify the strength of association between GSTM1 null genotype and risk of diabetes mellitus. We searched the PubMed, Embase and Wangfang databases for studies relating the association between GSTM1 null genotype and risk of diabetes mellitus. We estimated summary odds ratio (OR) with their 95 % confidence interval (95 % CI) to assess the association. Subgroup analyses were performed by type of diabetes and ethnicity. 10 case-control studies with 7, 054 subjects were included into this meta-analysis. Meta-analysis of total 10 studies showed GSTM1 null genotype was associated increased risk of diabetes mellitus (OR = 1.59, 95 % CI 1.14-2.22, P = 0.007). Subgroup analyses by type of diabetes mellitus suggested GSTM1 null genotype was associated increased risk of type 2 diabetes (OR = 1.90, 95 % CI 1.37-2.64, P < 0.001), but was not associated with risk of type 1 diabetes (OR = 0.84, 95 % CI 0.66-1.07, P = 0.153). Subgroup analysis by ethnicity further identified the obvious association between GSTM1 null genotype and increased risk of type 2 diabetes. The cumulative meta-analyses showed a trend of obvious association between GSTM1 null genotype and risk of type 2 diabetes as information accumulated. No evidence of publication bias was observed. Thus, evidence from current meta-analysis suggests an association between GSTM1 null genotype and risk of type 2 diabetes.
