GeneID: 57


Common Name: VDR Type: Gene
Chromosome: 12 (NC_000012.12) Locus: NG_008731.1 (VDR)
HUGO Symbol: VDR Full Name: vitamin D (1,25- dihydroxyvitamin D3) receptor
Exons: 10 Introns: 9

VDR is a member of the nuclear hormone receptor family, acting as a ligand-inducible transcription factor. Binding of the vitamin D3 ligand to the VDR mediates partnering of the latter with the retinoid X receptor (RXR) and formation of the VDR-RXR heterodimer, which in turn binds to vitamin D response elements (VDREs) located in the promoter region of the target genes, thereby regulating their transcription. Vitamin D can be obtained from food in the diet. Cholesterol is converted to vitamin D3 through the action of sunshine on the skin. Vitamin D3 is a major regulator of calcium metabolism and thus of bone formation, and plays an important role in cell growth, differentiation and immune functions. Mutations in this gene are associated with vitamin D-resistant rickets. Polymorphisms in this gene associated with bone mineral density (osteoporosis) in β-thalassemia patients. Alternative splicing results in multiple transcript variants encoding different proteins.
