Abstract:
Osteoporosis is characterized by reduced bone mineral density (BMD) and quality, increasing the risk of fractures. A large number of genes involved in bone metabolism have been implicated in the genesis of osteoporosis; these include RANK and RANKL. Polymorphisms of these genes have been implicated in osteoporosis. The aim of this study was to determine the association of the RANK rs3018362 and RANKL rs12585014 polymorphisms with risk of osteoporosis. Four hundred Mexican women aged 40 years old or above were genotyped by real-time PCR and several demographic and risk factors were explored. The GA and AA genotypes of the rs3018362 polymorphism were associated with a high risk of osteoporosis in the dominant model (p=.0062; OR = 2.16, 95% CI: 1.24-3.78). In summary, the rs3018362 polymorphism in the RANK gene seems to be associated with osteoporosis of the lumbar spine while the RANKL rs12585014 is not, although more studies are needed to confirm these results.
