Genes affected

PCDH15 (HGNC:14674): (protocadherin related 15) This gene is a member of the cadherin superfamily. Family members encode integral membrane proteins that mediate calcium-dependent cell-cell adhesion. It plays an essential role in maintenance of normal retinal and cochlear function. Mutations in this gene result in hearing loss and Usher Syndrome Type IF (USH1F). Extensive alternative splicing resulting in multiple isoforms has been observed in the mouse ortholog. Similar alternatively spliced transcripts are inferred to occur in human, and additional variants are likely to occur. [provided by RefSeq, Dec 2008]

Review Status: criteria provided, single submitter

Collection Method: curation

The p.Val528Asp variant in PCDH15 has been reported in 1 individual, in the homozygous state, with Usher syndrome type 1F (PMID: 19107147), segregated with disease in at least 3 affected relatives from 1 family (PMID: 19107147), and has been identified in 0.0009% (1/113622) of European (non-Finnish) chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP ID: rs267606932). Although this variant has been seen in the general population in a heterozygous state, its frequency is low enough to be consistent with a recessive carrier frequency. This variant has also been reported in ClinVar (Variation ID#: 18429) and has been interpreted as pathogenic by Invitae and OMIM. Computational prediction tools and conservation analyses suggest that this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, although additional studies are required to fully establish its clinical significance, this variant is likely pathogenic for autosomal recessive Usher syndrome type 1F. ACMG/AMP Criteria applied: PP1_moderate, PP3, PM2, PM3_supporting (Richards 2015). -

Variant summary: PCDH15 c.1583T>A (p.Val528Asp) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-06 in 251312 control chromosomes (gnomAD). c.1583T>A has been reported in the literature in multiple homozygous individuals affected with non-syndromic deafness (Doucette_2009). These data indicate that the variant is very likely to be associated with disease. The following publication has been ascertained in the context of this evaluation (PMID: 19107147). ClinVar contains an entry for this variant (Variation ID: 18429). Based on the evidence outlined above, the variant was classified as pathogenic. -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant is present in population databases (rs267606932, gnomAD 0.0009%). For these reasons, this variant has been classified as 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) performed at Invitae indicates that this missense variant is expected to disrupt PCDH15 protein function. ClinVar contains an entry for this variant (Variation ID: 18429). This missense change has been observed in individual(s) with nonsyndromic deafness (PMID: 19107147). It has also been observed to segregate with disease in related individuals. This sequence change replaces valine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 528 of the PCDH15 protein (p.Val528Asp). -
