Summaries for COL11A1 Gene

Entrez Gene Summary for COL11A1 Gene

  • This gene encodes one of the two alpha chains of type XI collagen, a minor fibrillar collagen. Type XI collagen is a heterotrimer but the third alpha chain is a post-translationally modified alpha 1 type II chain. Mutations in this gene are associated with type II Stickler syndrome and with Marshall syndrome. A single-nucleotide polymorphism in this gene is also associated with susceptibility to lumbar disc herniation. Multiple transcript variants have been identified for this gene. [provided by RefSeq, Nov 2009]

Disorders for COL11A1 Gene

(4) OMIM Diseases for COL11A1 Gene (120280)


  • Stickler syndrome 2 (STL2) [MIM:604841]: An autosomal dominant form of Stickler syndrome, an inherited disorder that associates ocular signs with more or less complete forms of Pierre Robin sequence, bone disorders and sensorineural deafness. Ocular disorders may include juvenile cataract, myopia, strabismus, vitreoretinal or chorioretinal degeneration, retinal detachment, and chronic uveitis. Pierre Robin sequence includes an opening in the roof of the mouth (a cleft palate), a large tongue (macroglossia), and a small lower jaw (micrognathia). Bones are affected by slight platyspondylisis and large, often defective epiphyses. Juvenile joint laxity is followed by early signs of arthrosis. The degree of hearing loss varies among affected individuals and may become more severe over time. Syndrome expressivity is variable. {ECO:0000269 PubMed:20513134, ECO:0000269 PubMed:8872475}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Marshall syndrome (MRSHS) [MIM:154780]: An autosomal dominant disorder characterized by ocular abnormalities, deafness, craniofacial anomalies, and anhidrotic ectodermal dysplasia. Clinical features include short stature; flat or retruded midface with short, depressed nose, flat nasal bridge and anteverted nares; cleft palate with or without the Pierre Robin sequence; appearance of large eyes with ocular hypertelorism; cataracts, either congenital or juvenile; esotropia; high myopia; sensorineural hearing loss; spondyloepiphyseal abnormalities; calcification of the falx cerebri; ectodermal abnormalities, including defects in sweating and dental structures. {ECO:0000269 PubMed:10486316}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Fibrochondrogenesis 1 (FBCG1) [MIM:228520]: A severe short-limbed skeletal dysplasia characterized by broad long-bone metaphyses, pear-shaped vertebral bodies, and characteristic morphology of the growth plate, in which the chondrocytes have a fibroblastic appearance and there are regions of fibrous cartilage extracellular matrix. Clinical features include a flat midface with a small nose and anteverted nares, significant shortening of all limb segments but relatively normal hands and feet, and a small bell-shaped thorax with a protuberant abdomen. {ECO:0000269 PubMed:21035103}. Note=The disease is caused by mutations affecting the gene represented in this entry.
