Genes affected

DIAPH1 (HGNC:2876): (diaphanous related formin 1) This gene is a homolog of the Drosophila diaphanous gene, and has been linked to autosomal dominant, fully penetrant, nonsyndromic sensorineural progressive low-frequency hearing loss. Actin polymerization involves proteins known to interact with diaphanous protein in Drosophila and mouse. It has therefore been speculated that this gene may have a role in the regulation of actin polymerization in hair cells of the inner ear. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The Pro1077Arg variant in DIAPH1 has been identified in 0.027% (1/3664) of Afric an American chromosomes from a broad population by the NHLBI Exome Sequencing Pr oject (http://evs.gs.washington.edu/EVS; dbSNP rs376593325). Computational analy ses (biochemical amino acid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide strong support for or against an impact to the protein. In summary, additional data is needed to determine the clinical significance of thi s variant. -

This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 1077 of the DIAPH1 protein (p.Pro1077Arg). This variant is present in population databases (rs376593325, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with DIAPH1-related conditions. ClinVar contains an entry for this variant (Variation ID: 163067). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
