The human vitamin D receptor (VDR) gene is located on chromosome 12q12–q14, and four commonnucleotide polymorphisms have been identified. Several studies have found a relationship betweenpolymorphisms of the (VDR) gene and development of type 1 diabetes (T1DM). The association ofVDR polymorphisms and susceptibility to T1DM in the Egyptian population were examined in 60individuals with type 1 diabetes and compared with healthy 60 persons. Single nucleotidepolymorphisms (SNP) genotyping was performed using PCR and BsmI and FokI, by using twotechniques, allele specific PCR technique and restriction fragment length polymorphism – PCR(RFLP-PCR). Data were analyzed using the chi square. The result approved that the genotype TA inSNP FokI was risk factor among type 1 diabetes mellitus patients combination which conferredstrongest susceptibility to T1DM (P=0.004) while the SNP BsmI did not showed any significancebetween cases as compared with control (P=0.493). The results of the current study indicated that VDRpolymorphisms are associated with increased risk of T1DM in the Egyptian population. The differencein the association of the aforementioned SNPs variants with T1DM among different populations maybe attributed to the presence of multiple susceptibility alleles.
