Genes affected

UTS2B (HGNC:30894): (urotensin 2B) Predicted to enable G protein-coupled receptor binding activity. Predicted to be involved in regulation of blood pressure. Predicted to be located in extracellular region. [provided by Alliance of Genome Resources, Apr 2022]

CCDC50 (HGNC:18111): (coiled-coil domain containing 50) This gene encodes a soluble, cytoplasmic, tyrosine-phosphorylated protein with multiple ubiquitin-interacting domains. Mutations in this gene cause nonsyndromic, postlingual, progressive sensorineural DFNA44 hearing loss. In mouse, the protein is expressed in the inner ear during development and postnatal maturation and associates with microtubule-based structures. This protein may also function as a negative regulator of NF-kB signaling and as an effector of epidermal growth factor (EGF)-mediated cell signaling. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Oct 2008]

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BP6: Variant 3-191328941-T-C is Benign according to our data. Variant chr3-191328941-T-C is described in ClinVar as Likely_benign. ClinVar VariationId is 1190935.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00552 (841/152310) while in subpopulation AFR AF = 0.019 (789/41570). AF 95% confidence interval is 0.0179. There are 7 homozygotes in GnomAd4. There are 410 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 7 AR gene
