Association of vitamin D receptor BsmI (rs1544410) gene polymorphism with the chronic kidney disease susceptibility

Abstract

Association of vitamin D receptor (VDR) BsmI (rs1544410) gene polymorphism with the chronic kidney disease (CKD) susceptibility from the published reports are still conflicting. This meta-analysis was performed to evaluate the relationship between VDR BsmI (rs1544410) gene polymorphism and the risk of CKD. The association studies were identified from PubMed, Cochrane Library and China Biological Medicine Database on 1 March 2014, and eligible investigations were included and synthesized using meta-analysis method. Nine reports were recruited into this meta-analysis for the association of VDR BsmI gene polymorphism with CKD susceptibility. In this meta-analysis for overall populations, the BsmI B allele BB genotype and bb genotype were not associated with the risk of CKD (B allele: OR?=?1.12, 95% CI: 0.88–1.44, p?=?0.36; BB genotype: OR?=?1.15, 95% CI: 0.81–1.62, p?=?0.43; bb genotype: OR?=?0.86, 95% CI: 0.61–1.20, p?=?0.36). Furthermore, VDR BsmI gene polymorphism was not associated with CKD susceptibility in Asians and in Caucasians. In conclusion, the BsmI gene polymorphism was not associated with CKD susceptibility in overall populations, in Asians and in Caucasians. However, more studies should be conducted to confirm it.
