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]

The Ala147Thr variant in ESPN has not been reported in individuals with hearing loss or in large population studies. Computational analyses (biochemical amino acid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide st rong support for or against an impact to the protein. In summary, additional inf ormation is needed to fully assess the clinical significance of the Ala147Thr va riant. -
