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 significance, criteria provided, single submitter	clinical testing	GeneDx	Aug 05, 2024	In silico analysis indicates that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 30019023) -
Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 25, 2024	This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 565 of the WFS1 protein (p.Leu565Val). This variant is present in population databases (rs200058166, gnomAD 0.02%). 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: 229638). 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. -

The p.Leu565Val variant in WFS1 has been previously reported by our laboratory i n the heterozygous state in 1 individual with hearing loss. This variant has bee n identified in 7/33580 Latino chromosomes by the Genome Aggregation Database (g nomAD, http://gnomad.broadinstitute.org/; dbSNP rs200058166). Although this vari ant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation ana lysis do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Leu565Val variant is uncertain. ACMG /AMP criteria applied: none. -

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 rs200058166 in Wolfram's syndrome yet. -
