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]

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

Variant classified as Uncertain Significance - Favor Benign. The p.Ser1622Gly va riant in PCDH15 has been previously identified by our laboratory in the heterozy gous state in one child with sensorineural hearing loss, who has a homozygous pa thogenic variant in another gene that explains the hearing loss. The p.Ser1622Gl y variant has also been identified in 8/67250 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs372184022) . Computational prediction tools and conservation analysis suggest that this var iant may not impact the protein, though this information is not predictive enoug h to rule out pathogenicity. In summary, while the clinical significance of the p.Ser1622Gly variant is uncertain, these data suggest that it is more likely to be benign. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.4864A>G (p.S1622G) alteration is located in exon 37 (coding exon 36) of the PCDH15 gene. This alteration results from a A to G substitution at nucleotide position 4864, causing the serine (S) at amino acid position 1622 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
