Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM1PM5

The NM_006005.3(WFS1):c.2054G>A(p.Arg685His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000161 in 1,612,740 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R685C) has been classified as Likely pathogenic.

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 WFS1 c.2054G>A; p.Arg685His variant (rs142668478), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 215395). This variant is found in the non-Finnish European population with an allele frequency of 0.03% (34/128384 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.688). Due to limited information, the clinical significance of this variant is uncertain at this time. -
