Importance of genetics in osteoartrosis

The study of our genome has played an important role in the field of personalized medicine and clinical practice becoming a useful tool to assist the medical community in the early diagnosis and treatment of countless diseases; osteoarthritis (OA) is a complex chronic degenerative joint disease, despite the high prevalence of this disease and its great impact on public health, little is currently known about its etiology and risk of progression. The purpose of this review is to show the advances in genetics in the study of osteoartrosis. The present is a review of the literature of the different aspects in which genetics has developed in the study of osteoartrosis, its scopes and its possible impact on prevention and treatment. The identification of a high number of candidate genes confirms the complex nature of the disease, it seems clear that the degree of expression of different genes is altered between an arthrosic patient and a healthy one. A deeper understanding of the link between the entire genome sequence and the association with well-characterized OA phenotypes will enable the development of biomarkers, report the risk of disease progression and allow better guidance of treatments.
