Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP4

The NM_031475.3(ESPN):​c.1094C>T​(p.Pro365Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000167 in 1,614,062 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. P365P) has been classified as Likely benign.

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 Pro365Leu variant in ESPN has not been reported in individuals with hearing loss but has been identified in 0.08% (1/1322) European chromosomes by the ClinS eq Project (dbSNP rs201251427). Computational analyses (amino acid properties, c onservation, AlignGVGD, PolyPhen2, SIFT) do not provide strong support for or ag ainst an impact to the protein. In summary, additional information is needed to determine the clinical significance of this variant. -
