▶Functional analysis of the osteoarthritis susceptibility–associated GDF5 regulatory polymorphismFunctionalRainer J. Egli et al.(2009)· Arthritis & Rheumatism
This functional study investigated the GDF5 SNP rs143383 (T-to-C), an established osteoarthritis susceptibility variant. Using differential allelic expression analysis in multiple joint tissues from OA patients, the authors demonstrated that the OA-risk T allele shows consistently reduced expression (mean T/C ratio 0.79) across all joint tissues tested, not just cartilage. They identified a second regulatory variant rs143384 in the GDF5 5'-UTR that modulates rs143383's effect, and a third variant (2250ct) in the 3'-UTR that acts independently to reduce expression. EMSA assays revealed that the transcription factor DEAF-1 binds preferentially to the T allele at rs143383.
About GDF5
This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer. This protein regulates the development of numerous tissue and cell types, including cartilage, joints, brown fat, teeth, and the growth of neuronal axons and dendrites. Mutations in this gene are associated with acromesomelic dysplasia, brachydactyly, chondrodysplasia, multiple synostoses syndrome, proximal symphalangism, and susceptibility to osteoarthritis.
