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	GeneDx	Jan 19, 2022	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 -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Oct 04, 2022	This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1376 of the PCDH15 protein (p.Ala1376Val). This variant is present in population databases (rs752371584, gnomAD 0.02%). 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: 972397). 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 not expected to disrupt PCDH15 protein function. 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. -

The c.4127C>T (p.A1376V) alteration is located in exon 30 (coding exon 29) of the PCDH15 gene. This alteration results from a C to T substitution at nucleotide position 4127, causing the alanine (A) at amino acid position 1376 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
