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 p.Ala425Thr variant in TRIOBP has not been previously reported in individual s with hearing loss or in large population studies. Computational prediction too ls and conservation analyses suggest that the variant may not impact the protein , though this information is not predictive enough to rule out pathogenicity. In summary, the clinical significance of the p.Ala425Thr variant is uncertain. -
