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]

Significance:Uncertain significance
Review Status:no assertion criteria provided
Collection Method:clinical testing

The DIAPH3 c.3538G>T variant is predicted to result in the amino acid substitution p.Val1180Phe. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0083% of alleles in individuals of African descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
