Association of vitamin D receptor BsmI gene polymorphism with the risk of type 2 diabetes mellitus

Abstract

Relationship between vitamin D receptor (VDR) BsmI (rs1544410) gene polymorphism and the type 2 diabetes mellitus (T2DM) susceptibility is still conflicting at present. This meta-analysis was conducted to assess the association between VDR BsmI gene polymorphism and the risk of T2DM. The association studies were identified from PubMed, and Cochrane Library on 1 January 2014, and eligible investigations were included and synthesized using meta-analysis method. Eleven reports were recruited into this meta-analysis for the association of VDR BsmI gene polymorphism with T2DM susceptibility. In overall populations, B allele, BB genotype and bb genotype were not associated with T2DM risk. VDR BsmI gene polymorphism was also not associated with the T2DM risk in Asians and Caucasians. In conclusion, VDR BsmI gene polymorphism was also not associated with T2DM risk in overall populations, Asians and Caucasians. However, more studies should be conducted to confirm it.
