الملخصSystemic lupus erythematosus (SLE) is a multifactorial autoimmune disorder that displays an important genetic background. Vitamin D3 (VD3) through its receptor (VDR) plays an important immunomodulatory role in autoimmune misbalance, being capable of modulating immune responses. Genetic alterations in VDR gene may contribute to an altered risk in SLE development and clinical manifestations. We investigated VDR SNPs (single nucleotide polymorphisms) frequencies in 128 SLE patients and 138 healthy controls (HC) and mRNA differential expression in 29 patients and 17 HC regarding SLE susceptibility as well as clinical features. We observed that rs11168268 G allele (OR = 1.55, p =.01) and G/G genotype (OR = 2.69, p =.008) were associated with increased SLE susceptibility. The rs2248098 G allele and A/G and G/G genotypes were associated to lower SLE susceptibility (OR = 0.66, p =.01; OR = 0.46, p =.01; OR = 0.44, p =.02, respectively). Regarding clinical features, we observed lower risk for: rs11168268 A/G genotype and nephritis (OR = 0.31, p =.01); rs4760648 T/T genotype and photosensitivity (OR = 0.24, p =.02); rs1540339 T/T genotype and antibody anti-dsDNA (OR = 0.19, p =.015); rs3890733 T/T genotype and serositis (OR = 0.10, p =.01). We identified a significant downregulation in VDR expression levels when compared patients and controls overall (p = 1.04e–7), in Cdx-2 A/G and G/G (p =.008 and p =.014, respectively) and in patients with nephritis (p =.016). Our results suggested that VDR SNPs influence upon SLE susceptibility and in particular clinical features, acting on mRNA expression in SLE patients overall and the ones with nephritis.
