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).

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.5185-12C>G variant in TRIOBP has not been previously reported in individua ls with hearing loss, but has been identified in 2/9786 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs 774556951). Although this variant has been seen in the general population, its f requency is not high enough to rule out a pathogenic role. This variant is locat ed in the 3' splice region. Computational tools do not suggest an impact to spli cing. However, this information is not predictive enough to rule out pathogenici ty. In summary, the clinical significance of the c.5185-12C>G variant is uncerta in. -
