Association of vitamin D receptor gene polymorphism with the risk of systemic lupus erythematosus.
Relationship between vitamin D receptor (VDR) gene polymorphism and the risk of systemic lupus erythematosus (SLE) from the published reports are still conflicting. This study was conducted to evaluate the relationship between VDR BsmI (rs1544410), Fok1 (rs2228570), ApaI (rs7975232) and TaqI (rs731236) gene polymorphism and the risk of SLE using meta-analysis method. The association studies were identified from PubMed and Cochrane Library on 1 March 2014, and eligible investigations were included and synthesized using meta-analysis method. Thirteen reports were recruited into this meta-analysis for the association of VDR gene polymorphism with SLE susceptibility. In this meta-analysis for overall populations, the BsmI B allele and bb genotype, Fok1 f allele and ff genotype, and ApaI aa genotype, were associated with the risk of SLE. In Asians, the BsmI B allele, BB genotype and bb genotype, Fok1 f allele and ff genotype were associated with the risk of SLE. In Africans, the BsmI B allele, BB genotype and bb genotype, Fok1 f allele and ff genotype, ApaI A allele, AA genotype and aa genotype were associated with the risk of SLE. However, VDR BsmI, Fok1, ApaI and TaqI gene polymorphism were not associated with the risk of SLE in Caucasians. In conclusion, the BsmI B allele and bb genotype, Fok1 f allele and ff genotype were associated with the risk of SLE in overall populations, and in Asians, but these associations were not found in Caucasians. However, more studies should be conducted to confirm it.
