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 was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.39218736).

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000283 (43/152074) while in subpopulation NFE AF = 0.000559 (38/68004). AF 95% confidence interval is 0.000418. There are 0 homozygotes in GnomAd4. There are 17 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The COL11A2 c.2555G>A; p.Arg852Gln variant (rs147927477), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 426242). This variant is found in the non-Finnish European population with an allele frequency of 0.04% (46/129,046 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.256). Due to limited information, the clinical significance of this variant is uncertain at this time. -

The p.Arg852Gln variant in COL11A2 has not been previously reported in individua ls with hearing loss, but has been identified in 46/ 126614 European chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; d bSNP rs147927477). Although this variant has been seen in the general population , its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation analysis suggest that this variant may impact the protein, though this information is not predictive enough to determine patho genicity. In summary, the clinical significance of the p.Arg852Gln variant is un certain. -
