Vitamin D Receptor Genotype Bone Loss in Japanese Patients Hyperparathyroidism Is Associated with Cort with Primary ica
نویسندگان
چکیده
Vitamin D receptor (VDR) genotype was determined in 66 Japanese patients with primary hyperparathyroidism (pHPT). In contrast to previous report showing an association between VDR genotype bb and the development of pHPT in a Swedish population, we did not find any differences in the frequencies of the VDR genotypes between pHPT and the control. The bone mineral density in the radius was significantly lower (Z score, -1.723 ± 1.819) in bb genotype than in BB/Bb genotype (+ 0.255 ± 2.344) in pHPT patients. Based on the fact that PTH requires vitamin D3 to take effect on calcium mobilization from bone, it is possible that VDR polymorphism may influence the PTH action on bone.

Background & objective: Ovarian cancer mortality is associated with lower regional sunlight exposure. Vitamin D and its metabolites are best known for their action in calcium and bone metabolism. However, epidemiological studies have suggested that an increased ovarian cancer risk is associated with decreased production of vitamin D. The vitamin D signaling pathway is involved in a wide variety...

BACKGROUND It remains unclear whether genetic factors may explain the reported variation in the levels of biochemical markers of chronic kidney disease mineral and bone disorders (CKD- MBD) across ethnic groups. Therefore, the aim of this study was to examine the influence of vitamin D receptor (VDR) polymorphisms on secondary hyperparathyroidism and its association with vitamin D levels in bla...

متن کاملThe Association of Vitamin D Receptor Gene BsmI Polymorphism with Multiple Sclerosis in Iranian Patients
Background & Aims: 1,25-dihydroxyvitamin D3 (1,25 (OH)2 D3), the biologically active form of vitamin D, exerts an immunosuppressive effect through binding to its specific nuclear receptor. The present case-control study was done to examine the possible association of BsmI polymorphism in vitamin D receptor gene (VDR gene) with severity of multiple sclerosis (MS). Methods: 267 Iranian patients w...
