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]

Gln1342Lys in exon 32 of PCDH15: This variant has been reported in the literatur e in an individual with Usher Type 1 and was not identified in 100 unaffected co ntrols (Ouyang 2005). However, this individual did not have a second pathogenic variant identified on the other allele. In addition, this variant was identified in our laboratory in an individual who did not have a PCDH15 variant on the oth er allele and the variant did not segregate with hearing loss and retinitis pigm entosa in that family. In addition, this variant is not expected to have clinica l significance because it has been identified in 2.3% (87/3738) of African Ameri can chromosomes in a broad population by the NHLBI Exome sequencing project (htt p://evs.gs.washington.edu/EVS/; rs61731387) -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: PCDH15 c.4024C>A (p.Gln1342Lys) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0018 in 251420 control chromosomes (gnomAD), predominantly at a frequency of 0.023 within the African or African-American subpopulation in the gnomAD database, including 7 homozygotes. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 7 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 African or African-American origin. Five ClinVar submitters have assessed this variant since 2014: three have classified the variant as likely benign and two as benign. Based on the evidence outlined above, the variant was classified as benign. -

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). 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. -
