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).

Pro1379Ser variant in exon 9 of TRIOBP: This variant is not expected to have cli nical significance due to a lack of conservation across species, including mamma ls. Of note, three mammals (Egyptian jerboa, cape golden mole, and wallaby) have a serine (Ser) at this position despite high nearby amino acid conservation. In addition, computational analyses do not suggest a high likelihood of impact to the protein. -
