Low hip bone mineral density(BMD)is an important index for osteoporosis and is associated with hip fracture,which leads to more cases of disability and mortality than all other kinds of fractures(Kanis et al.,2007).BMD’s heritability is more than 60%(Arden et al.,1996).A number of candidate loci for BMD have been previously identified by Genome Wide Association Studies(GWAS)(Xiong et al.,2009;Karasik et al.,2010;Zhang et al.,2013).Nevertheless,many significant signals based on GWAS are
Low hip bone mineral density (BMD) is an important index for osteoporosis and is associated with hip fracture, which leads to more cases of disability and mortality than all other kinds of fractures (Kanis et al., 2007). BMD’s heritability is more than 60% (Arden et al., 1996). A number of candidate loci for BMD have been previously identified by Genome Wide Association Studies (GWAS) (Xiong et al., 2009; Karasik et al., 2010; Zhang et al. 2013). However, many significant signals based on GWAS are
