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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant classified as Uncertain Significance - Favor Benign. The Ala207Ser varia nt in DFNB31 has not been reported in the literature but has been identified by our laboratory in one Black individual with unilateral hearing loss and an enlar ged vestibular aqueduct, though it was not felt that this variant was causative. Computational analyses (biochemical amino acid properties, conservation, AlignG VGD, PolyPhen2, and SIFT) suggest that the Ala207Ser variant may not impact the protein, though this information is not predictive enough to rule out pathogenic ity. In summary, the clinical significance of this variant cannot be determined with certainty; however based upon the computational predictions, we would lean towards a more likely benign role. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.619G>T (p.A207S) alteration is located in exon 2 (coding exon 2) of the WHRN gene. This alteration results from a G to T substitution at nucleotide position 619, causing the alanine (A) at amino acid position 207 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
