Background: The single nucleotide polymorphism (SNP) rs2615977 is associated with osteoarthritis (OA) and is located in intron 31 of COL11A1, a strong candidate gene for this degenerative musculoskeletal disease. Furthermore, the common non-synonymous COL11A1 SNP rs1676486 is associated with another degenerative musculoskeletal disease, lumbar disc herniation (LDH). rs1676486 is a C-T transition mediating its affect on LDH susceptibility by modulating COL11A1 expression.
View Article and Find Full Text PDFOsteoarthritis (OA) is a polygenic disease characterized by cartilage loss, with the single-nucleotide polymorphism (SNP) rs143383 (C/T) influencing OA susceptibility across a range of ethnic groups. The SNP resides within the 5'-UTR of the growth and differentiation factor 5 gene (GDF5), with the OA-associated T-allele mediating reduced GDF5 expression. As GDF5 codes for a cartilage anabolic protein, this reduced expression may explain why the T-allele of rs143383 is an OA risk factor.
