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]

Variant classified as Uncertain Significance - Favor Benign. The Glu1531Gly vari ant has not been reported in the literature nor previously identified by our lab oratory. The Glu (Glutamic acid) residue is conserved across mammals and computa tional analyses (PolyPhen, AlignGVGD) suggest that the Glu1531Gly variant may im pact the protein. However, this information is not predictive enough to assume p athogenicity. It should be noted that this lab has only sequenced the PCDH15 gen e in 138 individuals such that the full spectrum of benign variation has not yet been defined for this gene, increasing the possibility that this may be a benig n variant. In summary, the clinical significance of this variant cannot be deter mined with certainty at this time. -
