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 benign, no assertion criteria providedclinical testingDepartment of Pathology and Laboratory Medicine, Sinai Health System-The GIPC3 p.Val286Ile variant was not identified in the literature but was identified in dbSNP (ID: rs138339125) and ClinVar (classified as uncertain significance by GeneDx and EGL Genetics, as likely benign by Invitae and as benign by Laboratory for Molecular Medicine). The variant was identified in control databases in 326 of 273846 chromosomes (1 homozygous) at a frequency of 0.00119 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the following populations: Ashkenazi Jewish in 25 of 10050 chromosomes (freq: 0.002488), European (non-Finnish) in 243 of 124586 chromosomes (freq: 0.00195), European (Finnish) in 29 of 24102 chromosomes (freq: 0.001203), Other in 6 of 6970 chromosomes (freq: 0.000861), Latino in 21 of 34498 chromosomes (freq: 0.000609) and African in 2 of 24056 chromosomes (freq: 0.000083), but was not observed in the East Asian or South Asian populations. The p.Val286 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
