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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant classified as Uncertain Significance - Favor Benign. The Ser399Gly varia nt in PCDH15 has not been reported in the literature nor previously identified b y our laboratory. This variant is reported in dbSNP without frequency informatio n (dbSNP rs199786639). Computational analyses (biochemical amino acid properties , conservation, AlignGVGD, PolyPhen2, and SIFT) suggest that the Ser399Gly varia nt may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, the clinical significance of this variant cannot be determined with certainty; however based upon the computation predict ions, we would lean towards a more likely benign role. -
