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 p.Leu311Met variant in ESPN has not been previously reported in individuals with hearing loss and was absent from large population studies. Computational pr ediction tools and conservation analyses do not provide strong support for or ag ainst an impact to the protein. In summary, the clinical significance of the p.L eu311Met variant is uncertain.
