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]

Uncertain significance, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	May 05, 2015	The p.Ser342Phe variant in ESPN has not been previously reported in individuals with hearing loss, but has been identified in 8/66572 European chromosomes and 3 /11552 Latino chromosomes by the Exome Aggregation Consortium (ExAC, http://exac .broadinstitute.org; dbSNP rs199502924). Computational prediction tools and cons ervation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Ser342Phe variant is unc ertain. -

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Sep 23, 2023	This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 342 of the ESPN protein (p.Ser342Phe). This variant is present in population databases (rs199502924, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with ESPN-related conditions. ClinVar contains an entry for this variant (Variation ID: 228668). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	May 11, 2021	In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
