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 p.Glu2Lys variant in GIPC3 has not been previously reported in individuals w ith hearing loss or in large population studies. Computational prediction tools and conservation analysis suggest that the p.Glu2Lys variant may not impact the protein, though this information is not predictive enough to rule out pathogenic ity. In summary, the clinical significance of the p.Glu2Lys variant is uncertain . -
