Genes affected

ESPN (HGNC:13281): (espin) This gene encodes a multifunctional actin-bundling protein. It plays a major role in regulating the organization, dimensions, dynamics, and signaling capacities of the actin filament-rich, microvillus-type specializations that mediate sensory transduction in various mechanosensory and chemosensory cells. Mutations in this gene are associated with autosomal recessive neurosensory deafness, and autosomal dominant sensorineural deafness without vestibular involvement. [provided by RefSeq, Nov 2009]

p.Leu739Val in exon 10 of ESPN: This variant is not expected to have clinical si gnificance due to a lack of conservation across species, including mammals. Of n ote, 3 mammals (pika, manatee, and Tasmanian devil) have a valine (Val) at this position despite high nearby amino acid conservation. It has also been identifie d in 5/41504 European chromosomes by the Exome Aggregation Consortium (ExAC, htt p://exac.broadinstitute.org; dbSNP rs368795540). -
