New Susceptibility Loci for Osteoarthritis Identified: A Genome-wide Association Study
Osteoarthritis, a common type of arthritis, often leads to pain and disability in the older population. It is a multifactorial musculoskeletal disease with hereditary and environmental influences. Previous studies identified 3 of 11 genetic sites linked with osteoarthritis in European patients.
The current Genome-Wide Association Study (GWAS) of osteoarthritis, part of the Arthritis Research UK Osteoarthritis Genetics (arcOGEN) Consortium, was conducted in several thousands of unrelated osteoarthritis and population-based unrelated control patients.
The meta-analysis identified eight genetic loci with a link to increased risk of osteoarthritis occurrence. These included rs6976 on chromosome 3, and the loci close to ASTN2 (chromosome 9), between FILIP1 and SENP6 (chromosome 6), close to KLHDC5 and PTHLH (chromosome 9), close to CHST11 (chromosome 12) and the FTO gene.
These joint-specific inherited factors do influence osteoarthritis development and progression. The association of osteoarthritis with the FTO gene (the gene related to obesity) reiterates the fact that osteoarthritis is associated with body excess weight.
Thus, the newly discovered genetic influences contribute to increased risk for osteoarthritis and provide new targets for therapeutic action.
