(p = 0.02 for articular cartilage; p = 0.036 for joint ligament) Different COL11A2 expression was also demonstrated in tissue sections of cartilage and ligament tissues in DDH patients with different genotypes for rs9277935 with immunofluorescent assay, showing significantly greater COL11A2 expression in patients with TT genotype compared to those with GG genotype. Here, COL11A2 is linked to Hip dysplasia.
