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]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpApr 26, 2022This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 274 of the GIPC3 protein (p.Ala274Val). This variant is present in population databases (rs149028750, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with GIPC3-related conditions. ClinVar contains an entry for this variant (Variation ID: 517347). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Likely benign, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineApr 03, 2017p.Ala274Val in exon 6 of GIPC3: This variant is not expected to have clinical si gnificance due to a lack of conservation across species, including mammals. Of n ote, >10 mammals have a valine (Val) at this position despite high nearby amino acid conservation. In addition, computational prediction tools do not suggest a high likelihood of impact to the protein. It has also been identified in 4/54114 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.bro adinstitute.org; dbSNP rs149028750). -
