Genes affected

GIPC3 (HGNC:18183): (GIPC PDZ domain containing family member 3) The protein encoded by this gene belongs to the GIPC family. Studies in mice suggest that this gene is required for postnatal maturation of the hair bundle and long-term survival of hair cells and spiral ganglion in the ear. Mutations in this gene are associated with autosomal recessive deafness. [provided by RefSeq, Dec 2011]

The Phe292Ser variant in GIPC3 has not been previously reported in individuals w ith hearing loss, and frequency data from large population studies is insufficie nt. Computational tools (amino acid biochemical properties, conservation, SIFT, PolyPhen-2, AlignGVGD) suggest that this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary , additional information is needed to fully assess the clinical significance of this variant. -
