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]

c.1164-10C>T in intron 11 of DIAPH1: This variant is not expected to have clini cal significance because a C>T change at this position does not diverge from the splice consensus sequence and is therefore unlikely to impact splicing. It has been identified in 3/66712 European chromosomes by the Exome Aggregation Consort ium (ExAC, http://exac.broadinstitute.org). -
