Association of TWIST1 gene polymorphisms with bone mineral density in postmenopausal women

A novel polymorphism (+1871A>G) in the 3′ flanking region and haplotypes were significantly associated with reduced osteoporosis risk and enhanced bone mineral density (BMD). These results suggest that TWIST1 may...

Identification of novel RANK polymorphisms and their putative association with low BMD among postmenopausal women

Bone mineral density (BMD) is the major factor for determining bone strength, which is closely correlated to osteoporotic fracture risk and is largely determined by multiple genetic factors. The RANK (TNFRSF11A),...
