Genes affected

WFS1 (HGNC:12762): (wolframin ER transmembrane glycoprotein) This gene encodes a transmembrane protein, which is located primarily in the endoplasmic reticulum and ubiquitously expressed with highest levels in brain, pancreas, heart, and insulinoma beta-cell lines. Mutations in this gene are associated with Wolfram syndrome, also called DIDMOAD (Diabetes Insipidus, Diabetes Mellitus, Optic Atrophy, and Deafness), an autosomal recessive disorder. The disease affects the brain and central nervous system. Mutations in this gene can also cause autosomal dominant deafness 6 (DFNA6), also known as DFNA14 or DFNA38. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Mar 2009]

Uncertain:3

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Jul 21, 2020	Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 31363008) -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Aug 09, 2021	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 expected to disrupt WFS1 protein function. This sequence change replaces glutamic acid with lysine at codon 824 of the WFS1 protein (p.Glu824Lys). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and lysine. This variant is present in population databases (rs367547063, ExAC 0.002%). This missense change has been observed in individual(s) with clinical features of Wolfram/Wolfram-like syndrome (PMID: 31363008). ClinVar contains an entry for this variant (Variation ID: 166612). 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. -

Potent mutations in WFS1 gene are associated with Wolfram's syndrome, an autosomal recessive condition, which cause diabetes mellitus, diabetes insipidus, deafness and optic atrophy. However no sufficient evidence is found to ascertain the role of this particular variant rs367547063 in Wolfram's syndrome yet. -

Variant classified as Uncertain Significance - Favor Pathogenic. The Glu824Lys i n WFS1 has not been reported in affected individuals, but has been identified in 0.01% (1/8600) of European American chromosomes from a broad population by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/). Although thi s variant has been seen in this cohort, it should be noted that for diseases wit h clinical variability, reduced penetrance, or recessive inheritance, pathogenic variants may be present at a low frequency in the general population. Computati onal analyses (biochemical amino acid properties, conservation, AlignGVGD, PolyP hen2, and SIFT) do not provide strong support for or against an impact to the pr otein. In summary, additional information is needed to fully assess the clinical significance of this variant. -
