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]

c.2092-6T>C in intron 17 of PCDH15: This variant is not expected to have clinica l significance because a T>C change at this position does not diverge from the s plice consensus sequence and is therefore unlikely to impact splicing. It has be en identified in 2/16482 South Asian chromosomes by the Exome Aggregation Consor tium (ExAC, http://exac.broadinstitute.org; dbSNP rs780684363). -
