RCV000038648 | SCV000062326 | uncertain significance | not specified | 2013-01-17 | criteria provided, single submitter | clinical testing | The Trp648Leu variant in WFS1 has not been reported in the literature nor previo usly identified by our laboratory. Computational analyses (biochemical amino aci d properties, conservation, AlignGVGD, PolyPhen2, and SIFT) provide inconsistent predictions on the impact of the variant on the protein. Therefore, additional data is needed to determine the clinical significance of this variant. |

RCV003546463 | SCV004250949 | uncertain significance | not provided | 2023-05-18 | criteria provided, single submitter | clinical testing | 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. 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. ClinVar contains an entry for this variant (Variation ID: 45444). This variant has not been reported in the literature in individuals affected with WFS1-related conditions. This variant is present in population databases (rs150465110, gnomAD 0.002%). This sequence change replaces tryptophan, which is neutral and slightly polar, with leucine, which is neutral and non-polar, at codon 648 of the WFS1 protein (p.Trp648Leu). |
Ambry Genetics | RCV004018878 | SCV004979916 | uncertain significance | Inborn genetic diseases | 2023-11-14 | criteria provided, single submitter | clinical testing | The c.1943G>T (p.W648L) alteration is located in exon 8 (coding exon 7) of the WFS1 gene. This alteration results from a G to T substitution at nucleotide position 1943, causing the tryptophan (W) at amino acid position 648 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
