Genes affected

DIAPH3 (HGNC:15480): (diaphanous related formin 3) This gene encodes a member of the diaphanous subfamily of the formin family. Members of this family are involved in actin remodeling and regulate cell movement and adhesion. Mutations in this gene are associated with autosomal dominant auditory neuropathy 1. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

The c.3565A>G (p.R1189G) alteration is located in exon 28 (coding exon 28) of the DIAPH3 gene. This alteration results from a A to G substitution at nucleotide position 3565, causing the arginine (R) at amino acid position 1189 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
