Background Information

COL11A1 is an important component of collagen XI and is considered to play an important role in a variety of connective tissue diseases. Type XI collagen is widely distributed in tissues including cartilage, bone, and muscle, and its hereditary absence in Marshall's syndrome, Stickler's syndrome, fibrochondrogenesis, and nonsyndromic hearing loss deafness, autosomal dominant 37 leads to facial and eye abnormalities, hearing loss, and joint problems. The COL11A1 expression was significantly correlated with the degree of immune infiltration and the expression of a variety of immune cell markers in tumor tissue. (PMID: 36160004 33610546)
