Genes affected
COL11A2 (HGNC:2187): (collagen type XI alpha 2 chain) 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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000131 (20/152258) while in subpopulation AFR AF= 0.000361 (15/41530). AF 95% confidence interval is 0.000222. There are 0 homozygotes in gnomad4. There are 11 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

The p.Arg1431Trp variant in COL11A2 has not been previously reported in individu als with hearing loss, but has been identified in 6/9192 African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs 369126897). Although this variant has been seen in the general population, its f requency is not high enough to rule out a pathogenic role. Computational predict ion tools and conservation analysis suggest that this variant may impact the pro tein, though this information is not predictive enough to determine pathogenicit y. In summary, the clinical significance of the p.Arg1431Trp variant is uncertai n. -
