To discover if there is an association between the SNP rs143383 + 104T/C, in the GDF5 gene and the risk of developing KOA in individuals from northern Mexico.
These results strongly suggest that the C allele and CC genotype of the GDF5 gene are protective for knee OA susceptibility across different populations.
We observed demethylation of the GDF5 5'UTR in OA knee cartilage relative to both OA (p = 0.009) and non-OA (p = 0.001) hip cartilage, with the most significant demethylation observed at the highly conserved +37 CpG site located 4 bp upstream of rs143383.
Two thousand four hundred and sixty-two subjects aged 50 years and older were assessed for OA at the knee, were genotyped with two SNPs (GDF5; rs143383 and ADAM12; rs3740199).
That has proven to be the case for the GDF5 polymorphism rs143383, a risk factor for knee osteoarthritis and several other common conditions, including lumbar-disc degeneration and developmental dysplasia of the hip.
