Genes affected

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

Classification was made for transcript

Our verdict: Benign. The variant received -8 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 5: AlphaMissense, BayesDel_addAF, BayesDel_noAF, Cadd, Dann [when max_spliceai, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.013216823).

BP6

Variant 3-191380834-G-A is Benign according to our data. Variant chr3-191380834-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 162859.

BS2

High AC in GnomAd4 at 34 AD,Unknown gene.
