Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis was conducted to examine single nucleotide polymorphisms (SNPs) of the rs1544410 (BsmI, G>A), rs757343 (Tru9I, G>A), rs731236 (TaqI, T>C), and rs739837 (BglI, G>T) loci of the VDR gene in 334 healthy individuals (Hui 115, Han 219) and 355 T2DM patients (Hui 154, Han 201) living in the Ningxia Hui Autonomous Region of China.
Three tag single nucleotide polymorphisms (SNPs) (rs11574129, rs2228570, and rs739837) were genotyped using TaqMan assays to determine VDR SNP associations with dyslipidemia.
The results showed that subjects with the rs757343 A allele and rs739837</span> A allele had the significantly reduced risk of HCV susceptibility (all PBonferroni<0.05 in dominant/additive model).
Nevertheless, sub-group analyses revealed an association between rs2228570 (FokI) and absence of childhood sunburns (OR = 0.65, p = 0.003), between the 3'utr SNP rs739837 (BglI) and fair skin (OR = 1.31, p = 0.048), and between the promoter SNP rs4516035 and the more aggressive tumour location in head-neck and trunk (OR = 1.54, p = 0.020).
