Variant summary
Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM1BP4
The NM_006005.3(WFS1):c.2437G>A(p.Val813Met) variant causes a missense change. The variant allele was found at a frequency of 0.0000124 in 1,607,778 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V813L) has been classified as Uncertain significance.

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 813 of the WFS1 protein (p.Val813Met). This variant is present in population databases (rs756972444, gnomAD 0.007%). 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: 373968). 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) performed at Invitae 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. -
