Genotype analysis for VDR rs1544410, rs2228570, rs731236, and rs7975232 polymorphisms
Genomic DNA was extracted from peripheral blood samples using a Wizard Genomic DNA Purification Kit (Promega, Madison,Wisconsin, USA) as per the product instruction. VDR (rs731236, rs1544410, rs7975232, rs2228570) polymorphisms were genotyped by the improved Multiple Ligase Detection Reaction (iMLDR) developed by Genesky Biotechnologies Inc. (Shanghai, China).
