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.

Uncertain significance, criteria provided, single submitterclinical testingARUP Laboratories, Molecular Genetics and Genomics, ARUP LaboratoriesSep 05, 2017The p.Arg350Trp variant (rs142990800) has been reported in the medical literature in a single Egyptian individual with Usher syndrome (Aller 2010); however, inheritance and specific clinical information were not reported for this individual. The p.Arg350Trp variant is listed in the Genome Aggregation Database (gnomAD) browser with an allele frequency of 0.53% in the African population (identified in 128 out of 23,990 chromosomes; 1 homozygote), and is classified as likely benign in ClinVar (Variant ID: 178337). The arginine at codon 350 is moderately conserved considering 12 species (Alamut software v2.9.0), but computational analyses suggest that this variant affects the WHRN protein structure/function (SIFT: damaging, PolyPhen2: possibly damaging, MutationTaster: disease causing). While this variant appears to be a benign polymorphism in the African population, the available evidence is insufficient to classify the clinical significance of this variant with certainty. -
