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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineNov 05, 2015The p.Ser1678Leu variant in PCDH15 has not been previously reported in individua ls with hearing loss, but has been identified in 1/10404 of African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; rs143 438666). Computational prediction tools and conservation analysis suggest that t he p.Ser1678Leu variant may not impact the protein, though this information is n ot predictive enough to rule out pathogenicity. In summary, the clinical signifi cance of the p.Ser1678Leu variant is uncertain. -

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 19, 2024The c.5033C>T (p.S1678L) alteration is located in exon 33 (coding exon 32) of the PCDH15 gene. This alteration results from a C to T substitution at nucleotide position 5033, causing the serine (S) at amino acid position 1678 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 24, 2022This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 1678 of the PCDH15 protein (p.Ser1678Leu). This variant is present in population databases (rs143438666, 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: 229139). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
