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]

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Aug 12, 2022	This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 227 of the PCDH15 protein (p.Arg227Cys). This variant is present in population databases (rs565693539, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with PCDH15-related conditions. ClinVar contains an entry for this variant (Variation ID: 179459). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Sep 09, 2024	In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -

The p.Arg227Cys variant in PCDH15 has been identified in the heterozygous state in two individuals with hearing loss, one of whom had clinical features of Usher syndrome but was found to have an alternate genetic etiology (LMM data). This v ariant has also been identified in 0.04% (14/34350) of Latino chromosomes by gno mAD (http://gnomad.broadinstitute.org) and has been reported in ClinVar (Variati on ID 179459). Computational prediction tools and conservation analysis do not p rovide strong support for or against an impact to the protein. In summary, the c linical significance of the p.Arg227Cys variant is uncertain. ACMG/AMP Criteria applied: PM2_Supporting. -
