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 Arg339Gln variant in ESPN has not been previously reported in individuals wi th hearing loss, but has been identified in 0.01% (1/8600) of European American chromosomes and in 0.01% (1/4406) of African American chromosomes by the NHLBI E xome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs148390614). Computational prediction tools and conservation analysis do not provide strong s upport for or against an impact to the protein. In summary, the clinical signif icance of the Arg339Gln variant is uncertain. -

The c.1016G>A (p.R339Q) alteration is located in exon 6 (coding exon 6) of the ESPN gene. This alteration results from a G to A substitution at nucleotide position 1016, causing the arginine (R) at amino acid position 339 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
