Summary

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]

Forensic Context

A study in mice selectively bred for high or low methamphetamine consumption identified the COL11A2 as an extracellular matrix gene overexpressed in the ventral midbrain of the low-drinking line [Hitzemann et al. DOI:10.3390/brainsci9070155]. A study in humans demonstrated that total poly-ADP ribose polymerase (PARP) activity trended to be higher in the subcutaneous adipose tissue of heavier co-twins within body mass index-discordant monozygotic twin pairs, indicating an association between acquired obesity and increased activity of this major cellular NAD+ consumer [Jukarainen et al. DOI:10.1210/jc.2015-3095].
