Genes affected

TRIOBP (HGNC:17009): (TRIO and F-actin binding protein) This gene encodes a protein with an N-terminal pleckstrin homology domain and a C-terminal coiled-coil region. The protein interacts with trio, which is involved with neural tissue development and controlling actin cytoskeleton organization, cell motility and cell growth. The protein also associates with F-actin and stabilizes F-actin structures. Mutations in this gene have been associated with a form of autosomal recessive nonsyndromic deafness. Multiple alternatively spliced transcript variants that would encode different isoforms have been found for this gene, however some transcripts may be subject to nonsense-mediated decay (NMD).

The Gln1337Glu variant in TRIOBP has not been previously reported in individuals with hearing loss and frequency data from large population studies is insuffici ent. Computational prediction tools and conservation analyses do not provide str ong support for or against an impact to the protein. In summary, additional info rmation is needed to fully assess the clinical significance of this variant. -
