RCV001558648 | SCV002114098 | uncertain significance | not provided | 2024-12-05 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 358 of the WFS1 protein (p.Val358Leu). This variant is present in population databases (no rsID available, gnomAD 0.04%). 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: 1195529). 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. |

RCV005057510 | SCV005726153 | uncertain significance | not specified | 2024-11-20 | criteria provided, single submitter | clinical testing | Variant summary: WFS1 c.1072G>C (p.Val358Leu) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 6e-05 in 251434 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in WFS1 causing Wolfram Syndrome 1, allowing no conclusion about variant significance. To our knowledge, no occurrence of c.1072G>C in individuals affected with Wolfram Syndrome 1 and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 1195529). Based on the evidence outlined above, the variant was classified as uncertain significance. |
