Stickler syndrome is a connective tissue disorder that impacts several systems, consisting of the aesthetic system. Seven genes were reported to trigger Stickler syndrome in patients with different phenotypes. Forty-two probands identified with Stickler syndrome were consisted of. Pathogenic anomalies were found in 35 probands: 27 probands had COL2A1 mutations, and eight probands had COL11A1 anomalies. The anomaly features of probands with high nearsightedness or retinal detachment showed that the probands had a high frequency of COL2A1 anomalies, truncational anomalies, and de novo anomalies.

Stickler syndrome is a hereditary connective cells condition affecting bones, eyes, and hearing. Type 2 SS and the SS variant otospondylomegaepiphyseal dysplasia are caused by unhealthy versions in COL11A1 and COL11A2, respectively. We report four formerly unpublished intronic variations in COL11A1 and COL11A2 recognized in type 2 SS/OSMED people. We showed that all variations can induce exon in-frame deletions, which result in the synthesis of much shorter collagen XI α1 or 2 chains. In final thought, this study recommends that these alternative COL11A1 and COL11A2 records may lead to aberrant triple helix collagen.
