Variant summary
Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PP3_Moderate
The NM_006005.3(WFS1):c.1124G>A(p.Arg375His) variant causes a missense change. The variant allele was found at a frequency of 0.000333 in 1,614,082 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. R375C) has been classified as Uncertain significance.

Identified as heterozygous without a second variant in WFS1 in individuals with diabetes who had different genetic etiologies for their phenotypes (PMID: 31264968, 31638168); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 34426522, 26435059, 31638168, 31264968, 37444722, 32483926, 36672845) -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 375 of the WFS1 protein (p.Arg375His). This variant is present in population databases (rs142671083, gnomAD 0.05%). This missense change has been observed in individual(s) with WFS1-related coditions (PMID: 31264968, 31638168). ClinVar contains an entry for this variant (Variation ID: 504709). 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) has been performed 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. -
not specified Uncertain:1
The p.Arg375His variant in WFS1 has been previously reported by our laboratory i n one individual with hearing loss. This variant has also been identified in 60/ 126648 European chromosomes by the Genome Aggregation Database (gnomAD, http://g nomad.broadinstitute.org; dbSNP rs142671083); however, its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conser vation analyses do not provide strong support for or against an impact to the pr otein. In summary, the clinical significance of the p.Arg375His variant is uncer tain. -
