Study of the relationship between gene polymorphism of vitamin D receptor, calcitonin receptor and bone mineral density of the Han nationality woman in Hebei / 中国康复理论与实践

ABSTRACT

@#ObjectiveTo study the relationship between vitamin D receptor (VDR) gene polymorphism and calcitonin receptor (CTR) gene polymorphism, and bone mineral density (BMD) of the Han nationality woman in Hebei, explore the pathogenesis of osteoporosis (OP) at the gene level.MethodsPolymorphisms of VDR gene and CTR gene were analyzed by restriction fragment length polymorphisms (RFLPs) in 60 Han nationality women in Hebei.ResultsBb genetype of VDR had lower BMD values at all sites which were measured compared with bb genetype (P<0.05); CC genetype of CTR had tendency for lower BMD values at the L1～L4 compared with CT genetype (0.05<P<0.1); BMD value of CCBb genetype was the lowest.ConclusionBb genetype of VDR has a relationship with lower BMD. CCBb genetype can act as a heredity mark of OP in Chinese Han nationality woman.
