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	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Mar 28, 2024	The WFS1 c.1760G>A; p.Arg587Gln variant (rs71539657) is reported in the literature in a homozygous individual with vision loss and type 1 diabetes (Li 2018). This variant is reported in ClinVar (Variation ID: 215361). This variant is found in the general population with an overall allele frequency of 0.05% (144/282,766 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses predict that this variant is neutral (REVEL: 0.119). While the high population frequency suggests that this is likely a benign variant, given the limited clinical data and lack of functional data, the significance of this variant is uncertain at this time.

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	May 24, 2016	The R587Q variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The NHLBI Exome Sequencing Project reports R587Q was observed in 4/8,600 alleles from individuals of European background. The R587Q variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is not conserved, and in silico analysis predicts this variant likely does not alter the protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. -
Benign, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	May 02, 2017	p.Arg587Gln in exon 8 of WFS1: This variant is not expected to have clinical sig nificance because of its frequency in the general population and the lack of con servation of the amino acid. It has been identified in 0.4% (37/10152) of Ashke nazi Jewish chromosomes Genome Aggregation Database (gnomAD, http://gnomad.broad institute.org; dbSNP rs71539657). The arginine (Arg) at position 587 is not cons erved across species with 1 mammal (bushbaby) and 10 fish species having a gluta mine (Gln). Additional computational prediction tools do not suggest an impact t o the protein. -

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

The WFS1 c.1760G>A variant is predicted to result in the amino acid substitution p.Arg587Gln. This variant was reported in the homozygous state in an individual with Wolfram syndrome (Li et al. 2018. PubMed ID: 29549887). This variant is reported in 0.36% of alleles in individuals of Ashkenazi Jewish descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. -
