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]

Likely pathogenic, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineApr 04, 2017The p.Ala29ProfsX68 variant in GIPC3 has not been previously reported in individuals with hearing loss and was present in 0.06% (1/1748) of European chromosomes studies by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs756840753). This variant is predicted to cause a frameshift, which alters the protein’s amino acid sequence beginning at position 29 and leads to a premature termination codon 68 amino acids downstream. This alteration is then predicted to lead to a truncated or absent protein. Although this variant has been seen in the general population, its frequency is low enough to be consistent with a recessive carrier frequency. In summary, although additional studies are required to fully establish its clinical significance, the p.Ala29ProfsX68 variant is likely pathogenic for autosomal recessive hearing loss based upon predicted impact and low allele frequency. -
