Genes affected

WHRN (HGNC:16361): (whirlin) This gene is thought to function in the organization and stabilization of sterocilia elongation and actin cystoskeletal assembly, based on studies of the related mouse gene. Mutations in this gene have been associated with autosomal recessive non-syndromic deafness and Usher Syndrome. Alternative splicing results in multiple transcript variants.

The Arg242His variant in DFNB31has not been previously reported in individuals w ith hearing loss and was absent from large population studies. Computational pre diction tools and conservation analysis suggest that the Arg242His variant may n ot impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, the clinical significance of the Arg242His varia nt is uncertain. -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 242 of the WHRN protein (p.Arg242His). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with WHRN-related conditions. ClinVar contains an entry for this variant (Variation ID: 179786). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C25"). 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. -
