Genetic Variant WFS1:p.Arg558Cys (chr4-6301467-C-T) – ACMG Classification: Likely_pathogenic (8 pts)

Variant summary

Our verdict is Likely pathogenic. The variant received 8 ACMG points: 13P and 5B. PM1PM5PP3PP5_Very_StrongBP4BS2

The NM_006005.3(WFS1):c.1672C>T(p.Arg558Cys) variant causes a missense change. The variant allele was found at a frequency of 0.000348 in 1,612,648 control chromosomes in the GnomAD database, including 4 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R558H) 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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 8 ACMG points.

PM1

In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 5 benign, 18 uncertain in NM_006005.3

PM5

Other missense variant is known to change same aminoacid residue: Variant chr4-6301468-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 427051.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

PP3

Multiple lines of computational evidence support a deleterious effect 9: AlphaMissense, BayesDel_noAF, Cadd, Dann, Eigen, M_CAP, PROVEAN, REVEL, REVEL [when max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]

PP5

Variant 4-6301467-C-T is Pathogenic according to our data. Variant chr4-6301467-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 198835.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP4

Computational evidence support a benign effect (MetaRNN=0.24366054). . Strength limited to SUPPORTING due to the PP5.

BS2

High Homozygotes in GnomAdExome4 at 4 AD,AR,Unknown gene
