Variant summary

Our verdict is Uncertain significance. The variant received 5 ACMG points: 5P and 0B. PM3PP3PP4PM2_Supporting

This summary comes from the ClinGen Evidence Repository: The NM_022124.6:c.478G>A variant in the CDH23 gene is a missense variant predicted to cause substitution of aspartic acid to asparagine at amino acid 160 (p.Asp160Asn). The computational predictor REVEL gives a score of 0.8, evidence that correlates with impact to CDH23 function (PP3). The highest population minor allele frequency in gnomAD v2.1.1 is 0.0008% (1/112644 alleles) in the European (non-Finnish) population, which is lower than the ClinGen Hearing Loss VCEP threshold (<0.007%) for PM2_Supporting. This variant has been identified in one individual homozygous for the variant with Usher syndrome (PMID:2746042, 0.5 PM3 points, PP4). Another individual with hearing loss and cochlear implants at age 1 year harbored this variant and another pathogenic variant, though phase was unknown (PMID:35020051, 0.5 PM3 points). A third individual with Usher syndrome had a variant of uncertain significance phase unknown (Invitae internal data, SCV001516999.2, 0 PM3 points). It has been reported in additional individuals with hearing loss who either did not have an age of onset noted or did not have a second variant reported (PMID:35020051, 22899989). In summary, due to limited evidence, this variant is classified as a variant of uncertain significance based on the ACMG/AMP criteria applied, as specified by the ClinGen Hearing Loss Variant Curation Expert Panel: PM2_supporting, PM3, PP3, PP4.

Genes affected

CDH23 (HGNC:13733): (cadherin related 23) This gene is a member of the cadherin superfamily, whose genes encode calcium dependent cell-cell adhesion glycoproteins. The encoded protein is thought to be involved in stereocilia organization and hair bundle formation. The gene is located in a region containing the human deafness loci DFNB12 and USH1D. Usher syndrome 1D and nonsyndromic autosomal recessive deafness DFNB12 are caused by allelic mutations of this cadherin-like gene. Upregulation of this gene may also be associated with breast cancer. Alternative splice variants encoding different isoforms have been described. [provided by RefSeq, May 2013]

Labcorp Genetics (formerly Invitae), Labcorp

Significance:Likely pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on CDH23 protein function. This variant is present in population databases (no rsID available, gnomAD 0.0009%). ClinVar contains an entry for this variant (Variation ID: 375463). This missense change has been observed in individual(s) with CDH23-related conditions (PMID: 22899989, 27460420; Invitae). This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 160 of the CDH23 protein (p.Asp160Asn). -

Review Status:reviewed by expert panel

Collection Method:curation

The NM_022124.6:c.478G>A variant in the CDH23 gene is a missense variant predicted to cause substitution of aspartic acid to asparagine at amino acid 160 (p.Asp160Asn). The computational predictor REVEL gives a score of 0.8, evidence that correlates with impact to CDH23 function (PP3). The highest population minor allele frequency in gnomAD v2.1.1 is 0.0008% (1/112644 alleles) in the European (non-Finnish) population, which is lower than the ClinGen Hearing Loss VCEP threshold (<0.007%) for PM2_Supporting. This variant has been identified in one individual homozygous for the variant with Usher syndrome (PMID: 2746042, 0.5 PM3 points, PP4). Another individual with hearing loss and cochlear implants at age 1 year harbored this variant and another pathogenic variant, though phase was unknown (PMID: 35020051, 0.5 PM3 points). A third individual with Usher syndrome had a variant of uncertain significance phase unknown (Invitae internal data, SCV001516999.2, 0 PM3 points). It has been reported in additional individuals with hearing loss who either did not have an age of onset noted or did not have a second variant reported (PMID: 35020051, 22899989). In summary, due to limited evidence, this variant is classified as a variant of uncertain significance based on the ACMG/AMP criteria applied, as specified by the ClinGen Hearing Loss Variant Curation Expert Panel: PM2_supporting, PM3, PP3, PP4.
