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]

The p.Arg457Ser variant in WFS1 has been reported in one individual with atypica l Wolfram syndrome (Giuliano 2005). However, a variant affecting the remaining c opy of WFS1 was not identified in this individual, and a dominant family history of hearing loss was not described. This variant has been identified in 0.06% (3 9/66642) of European chromosomes by the Exome Aggregation Consortium (ExAC, http ://exac.broadinstitute.org; dbSNP rs113446173); however, its frequency is not hi gh enough to rule out a pathogenic role. Computational prediction tools and cons ervation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of this variant is uncertain. -

Collection Method: clinical testing

The c.1371G>T (p.R457S) alteration is located in exon 8 (coding exon 7) of the WFS1 gene. This alteration results from a G to T substitution at nucleotide position 1371, causing the arginine (R) at amino acid position 457 to be replaced by a serine (S). Based on data from gnomAD, the T allele has an overall frequency of 0.03% (87/281,212) total alleles studied. The highest observed frequency was 0.06% (79/128,706) of European (non-Finnish) alleles. This amino acid position is not well conserved in available vertebrate species. The in silico prediction for this alteration is inconclusive. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The WFS1 c.1371G>T variant is predicted to result in the amino acid substitution p.Arg457Ser. This variant was reported in the heterozygous state without a second potentially causative variant in an individual with Wolfram syndrome (Giuliano. 2005. PubMed ID: 15605410) and in an individual with hearing loss (Table S1, Sommen. 2016. PubMed ID: 27068579). This variant is reported in 0.061% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/4-6302893-G-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
