Rs7646054

rs7646054 is a SNP in the ARHGEF3 gene.

A study of 769 Australian female siblings found that the rs7646054(G) allele was significantly associated with lower bone mineral density (BMD) and thus osteoporosis in an age-related manner. Significant associations with hip and spine BMD were confirmed (p = 0.003-0.038), as well as an association with fracture rate (p = 0.02).
