summary for human COL11A2

This gene encodes one of the two alpha chains of type XI collagen, a minor fibrillar collagen. It is located on chromosome 6 very close to but separate from the gene for retinoid X receptor beta. Type XI collagen is a heterotrimer but the third alpha chain is a post-translationally modified alpha 1 type II chain. Proteolytic processing of this type XI chain produces PARP, a proline/arginine-rich protein that is an amino terminal domain. Mutations in this gene are associated with type III Stickler syndrome, otospondylomegaepiphyseal dysplasia (OSMED syndrome), Weissenbacher-Zweymuller syndrome, autosomal dominant non-syndromic sensorineural type 13 deafness (DFNA13), and autosomal recessive non-syndromic sensorineural type 53 deafness (DFNB53). Alternative splicing results in multiple transcript variants. A related pseudogene is located nearby on chromosome 6. [provided by RefSeq, Jul 2009]

nomenclature changes

04/22/ 2016

Human name has changed for Entrez Gene: 394214. From collagen, type XI, alpha 2 pseudogene 1 to collagen type XI alpha 2 pseudogene 1

3OCT2023

Renamed gene, changing from col11a2p1 to col11a2, removing ‘p1’ suffix as these are protein coding genes in Xenopus.

Humans have a true pc gene and an adjacent pseudogene on Chr6, flanked by BRD2 and RXRB. Xenopus tropicalis and X.laevis.S both have orthologous genes.

Also, removed the human COL11A2P1 as ortholog from this gene page (done)

Orthology and Synteny

Synteny shows that these genes are the true orthologs of human COL11A2, and therefore orthologs were moved from XB-GENEPAGE-12564498 to XB-GENEPAGE-876668
