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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant classified as Uncertain Significance - Favor Benign. The p.Gly402Ala var iant in PCDH15 has been reported in the heterozygous state in 1 individual with hearing loss (Besnard 2014). It has also been identified in 0.26% (62/24036) of African chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.br oadinstitute.org; dbSNP rs145017164). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic r ole. Computational prediction tools and conservation analysis do not provide str ong support for or against an impact to the protein. In summary, while the clini cal significance of the p.Gly402Ala variant is uncertain, its frequency suggests that it is more likely to be benign. ACMG/AMP Criteria applied: BS1_supporting. -

Significance:Uncertain significance

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). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
