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]

Val1800Ile in exon 33 of PCDH15: This variant is not expected to have clinical s ignificance because it has been identified in 0.7% (94/13018) of South Asian chr omosomes, including 1 homozygote, by the Exome Aggregation Consortium (ExAC, htt p://exac.broadinstitute.org; dbSNP rs111033463). In addition, the valine (Val) residue at position 1800 is not conserved in several species, with chimpanzee an d macaque having an isoleucine (Ile) at this position. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

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. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
