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]
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]
