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).

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineApr 20, 2015The p.Glu2069Lys variant in TRIOBP has not been previously reported in individua ls with hearing loss or in large population studies. Computational prediction to ols and conservation analyses suggest that the variant may not impact the protei n, though this information is not predictive enough to rule out pathogenicity. I n summary, the clinical significance of the p.Glu2069Lys variant is uncertain. -
