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]

ACMG classification

Verdict is Benign. Variant got -13 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.46).
• BP6: Variant 19-3585729-G-C is Benign according to our data. Variant chr19-3585729-G-C is described in ClinVar as [Likely_benign]. Clinvar id is 227377.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-0.645 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0017 (258/152090) while in subpopulation AFR AF= 0.00602 (250/41536). AF 95% confidence interval is 0.00541. There are 1 homozygotes in gnomad4. There are 112 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
