RCV000152674 | SCV000202036 | uncertain significance | not specified | 2016-02-07 | criteria provided, single submitter | clinical testing | The p.Ala433Thr variant in WFS1 has not been previously reported in individuals with hearing loss or Wolfram syndrome. This variant has been identified in 8/66 730 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac. broadinstitute.org; dbSNP rs138771366); however, its frequency is not high enoug h to rule out a pathogenic role. Computational prediction tools and conservation analyses suggest that the p.Ala433Thr variant may not impact the protein, thoug h this information is not predictive enough to rule out pathogenicity. In summar y, the clinical significance of the p.Ala433Thr variant is uncertain. |

RCV001298335 | SCV001487387 | uncertain significance | not provided | 2024-11-05 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 433 of the WFS1 protein (p.Ala433Thr). This variant is present in population databases (rs138771366, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with WFS1-related conditions. ClinVar contains an entry for this variant (Variation ID: 166587). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt WFS1 protein function with a negative predictive value of 95%. 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. |
Ambry Genetics | RCV003278672 | SCV003954148 | uncertain significance | Inborn genetic diseases | 2023-04-12 | criteria provided, single submitter | clinical testing | The c.1297G>A (p.A433T) alteration is located in exon 8 (coding exon 7) of the WFS1 gene. This alteration results from a G to A substitution at nucleotide position 1297, causing the alanine (A) at amino acid position 433 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
