RCV000199551 | SCV002283056 | uncertain significance | not provided | 2023-12-14 | criteria provided, single submitter | clinical testing | This sequence change replaces phenylalanine, which is neutral and non-polar, with cysteine, which is neutral and slightly polar, at codon 439 of the WFS1 protein (p.Phe439Cys). This variant is present in population databases (rs141585847, gnomAD 0.01%). This missense change has been observed in individual(s) with clinical features of WFS1-related conditions (PMID: 24890733). ClinVar contains an entry for this variant (Variation ID: 215388). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on WFS1 protein function. 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. |

RCV004530180 | SCV004716134 | uncertain significance | WFS1-related disorder | 2023-10-26 | no assertion criteria provided | clinical testing | The WFS1 c.1316T>G variant is predicted to result in the amino acid substitution p.Phe439Cys. This variant was reported in the heterozygous state in an individual with early onset Wolfram syndrome (Chaussenot et al. 2015. PubMed ID: 24890733). This variant is reported in 0.012% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/4-6302838-T-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
