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 submitterclinical testingGeneDxJun 18, 2018This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Likely benign, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJan 12, 2017p.Gly1151Arg in exon 26 of PCDH15: This variant is not expected to have clinical significance because it has been identified in 1.7% (322/18942) of East Asian c hromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstit ute.org/; dbSNP rs149478475). -
Benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpJul 12, 2022Variant summary: PCDH15 c.3451G>A (p.Gly1151Arg) results in a non-conservative amino acid change located in the Cadherin-like domain (IPR002126) of 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 0.0013 in 250984 control chromosomes, predominantly at a frequency of 0.017 within the East Asian subpopulation in the gnomAD database, including 2 homozygotes. The observed variant frequency within East Asian control individuals in the gnomAD database is approximately 5 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 East Asian origin. To our knowledge, no experimental evidence demonstrating its impact on protein function have been reported. Six ClinVar submitters (evaluation after 2014) cite the variant as likely benign (n=3) and benign (n=3). Based on the evidence outlined above, the variant was classified as benign. -

Likely benign, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaApr 27, 2017This 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). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
