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]

Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Mar 11, 2022	Variant summary: PCDH15 c.1039C>T (p.Leu347Phe) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0038 in 251374 control chromosomes, predominantly at a frequency of 0.005 within the Non-Finnish European subpopulation in the gnomAD database, including 3 homozygotes. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 1.6 fold of the estimated maximal expected allele frequency for a pathogenic variant in PCDH15 causing Usher Syndrome Type 1F phenotype (0.0032), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. Although reported in the literature, to our knowledge, no penetrant association of c.1039C>T in individuals affected with Usher Syndrome Type 1F and no experimental evidence demonstrating its impact on protein function have been reported. Six clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories reported the variant with conflicting assessments and a majority consensus as Benign (n=4) (VUS, n=2). Based on the evidence outlined above, the variant was classified as benign. -
Benign, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Sep 22, 2016	p.Leu347Phe in exon 10 of PCDH15: This variant has not been reported in the lite rature but has now been identified by our laboratory in 5/197 (2.5%) individuals with hearing loss yet none of these individuals had a second PCDH15 variant and one family had an alternate cause of hearing loss. In summary, this data sugges ts that the variant is benign. This variant is not expected to have clinical sig nificance, because it has been identified in 355/66702 European chromosomes by t he Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs1 11033436). -

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
