[Population genetic correlation of vitamin D receptor polymorphisms with clinical disorders].
Calcitriol, the active metabolite of Vitamin D (1,25(OH)2D3) has several major roles in the body: hormonal regulation of calcium and phosphate-homeostasis, regulation of parathormone synthesis and modulation of the immune and endocrine systems. Due to its antiproliferative effects it also plays a role in tumour development. The calcitriol can have these differential effects as it is modulating gene expression in the cell nucleus. The effects of vitamin D are mediated by the nuclear vitamin D receptor, which heterodimerizes with the retinoid X receptor and changes gene transcription. Until now 5 single nucleotide polymorphisms of the vitamin D receptor gene have been identified. This review summarizes the identified effects of vitamin D receptor polymorphisms on bone homeostasis, on the parathyroid function, on diversal tumours and on diabetes.
