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

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BP6: Variant 9-114424385-A-G is Benign according to our data. Variant chr9-114424385-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 45652.
• BP7: Synonymous conserved (PhyloP=-5.16 with no splicing effect.
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00285 (434/152288) while in subpopulation NFE AF = 0.00454 (309/68004). AF 95% confidence interval is 0.00413. There are 2 homozygotes in GnomAd4. There are 194 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 2 AR gene
