功能： disease:Defects in COL9A2 are the cause of multiple epiphyseal dysplasia type 2 (EDM2) [MIM:600204]. EDM is a generalized skeletal dysplasia associated with significant morbidity. Joint pain, joint deformity, waddling gait, and short stature are the main clinical signs and symptoms. EDM is broadly categorized into the more severe Fairbank and the milder Ribbing types. EDM2 inheritance is autosomal dominant.,disease:Defects in COL9A2 may be a cause of susceptibility to intervertebral disc disease (IDD) [MIM:603932]. IDD is one of the most common musculo-skeletal disorders.,function:Structural component of hyaline cartilage and vitreous of the eye.,PTM:Covalently linked to the telopeptides of type II collagen by lysine-derived cross-links.,PTM:Prolines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains.,similarity:Belongs to the fibril-associated collagens with interrupted helices (FACIT) family.,subunit:Heterotrimer of an alpha 1(IX), an alpha 2(IX) and an alpha 3(IX) chain.,
