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.

ACMG classification
Classification made for transcript
Verdict is Likely_benign. Variant got -3 ACMG points.
PM2
?
Very rare variant in population databases, with high coverage;
BP4
?
Computational evidence support a benign effect (MetaRNN=0.05598885).
BS1
?
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000105 (16/152118) while in subpopulation SAS AF= 0.00332 (16/4816). AF 95% confidence interval is 0.00208.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Oct 17, 2022 | This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 110 of the WHRN protein (p.Thr110Ala). This variant is present in population databases (rs572312301, gnomAD 0.2%). 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: 178844). 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: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). 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. - |

Autosomal recessive nonsyndromic hearing loss 31 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Jan 13, 2018 | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. - |
