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]

The p.Arg1578Cys variant in PCDH15 has been previously reported in 1 individual with hearing loss by our laboratory; however, a variant affecting the remaining copy of PCDH15 was not identified in this individual. This variant has been iden tified in 2/11518 Latino chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs566386133); however, its frequency is no t high enough to rule out a pathogenic role. Computational prediction tools and conservation analysis are limited or unavailable for this variant. In summary, t he clinical significance of the p.Arg1578Cys variant is uncertain. -
