ARELLANO-PEREZ-VERTTI, RD et al. D-repeat polymorphism in the ASPN gene in knee osteoarthritis in females in Torreón, Coahuila: Case-control study. Acta ortop. mex [online]. 2014, vol.28, n.6, pp.363-368. ISSN 2306-4102.

Background: Knee osteoarthritis (OA) is one of the most common and disabling disorders of the musculoskeletal system. It may affect any ethnic group and causes variable degrees of disability. Various risk factors have been associated with the development and progression of this condition, such as: age, genetic and occupational factors, trauma, menopause, diabetes mellitus, obesity, and gender, among others. Distinguishing these factors, whether individually or altogether, is important to prevent or diagnose and treat the disease early on. Methods: A case-control study was conducted in 260 females in Torreón, Coahuila, to analyze the relationship between primary knee osteoarthritis and the D-repeat polymorphism in the ASPN gene (asporin). 130 females with knee osteoarthritis and 130 healthy female controls were included. Results: In this study, menopause and the D16 allele variant were found to be significant risk factors for knee osteoarthritis (p = 0.002, OR 2.656, CI 95% 1.412-4.998; p = 0.026, OR 2.418, CI 95% 1.111-5.263, respectively). The D12 variant was found to be a significant protective allele. Conclusions: As far as we know, this is the first case-control study in Mexican women that suggests that menopause and the D-repeat polymorphism in the ASPN gene are associated with knee OA.
