Undiagnosed metabolic disorders
Gene: WFS1Comment on phenotypes: Original phenotypes were: Wolfram syndrome 1 (Mitochondrial respiratory chain disorders (caused by nuclear variants only)); Congenital hearing impairment (profound/severe); Diabetes with additional phenotypes suggestive of a monogenic aetiology; Familial diabetes; Hereditary ataxia; Inherited optic neuropathies.Created: 6 May 2021, 9:36 a.m. | Last Modified: 6 May 2021, 9:36 a.m.

PMID: 33693650 - Panfili et al 2021 - report an additional case of an 11 year old patient with Wolfram syndrome (diabetes mellitus and initial signs of optic atrophy) in which 2 novel variants in WFS1, c.316-1G > A (in intron 3) and c.757A > T (in exon 7), were identified by WES. Both are predicted to produce truncated and inactive protein. One variant was inherited from each parent. Most disease associated variants to date have been found in exon 8. Wildtype WFS1 protein was absent in peripheral blood mononuclear cells of the proband and there was no evidence of ER stress activation but very high levels of proinflammatory cytokines and a high ratio of proinflammatory T helper type 17 cells to regulatory T cells was found, suggesting that WFS1 deficiency may cause effects other than alterations in unfolded protein response (UPR) signaling pathways related to ER stress.Created: 6 May 2021, 9:35 a.m. | Last Modified: 6 May 2021, 9:35 a.m.

Comment on list classification: Promoted from Amber to Green. WFS1 is associated with an appropriate phenotype on OMIM and Gene2Phenotype. There are >3 unrelated cases listed on OMIM. Therefore, enough evidence for this gene to be promoted to Green status.Created: 16 Oct 2019, 2:57 p.m. | Last Modified: 16 Oct 2019, 2:57 p.m.

Mode of inheritance
BOTH monoallelic and biallelic, autosomal or pseudoautosomal
Phenotypes
Inherited optic neuropathies
Phenotypes for gene: WFS1 were changed from Wolfram syndrome 1 (Mitochondrial respiratory chain disorders (caused by nuclear variants only)); Congenital hearing impairment (profound/severe); Diabetes with additional phenotypes suggestive of a monogenic aetiology; Familial diabetes; Hereditary ataxia; Inherited optic neuropathies to Wolfram syndrome 1, OMIM:222300
Publications for gene: WFS1 were set to 27604308
Gene: wfs1 has been classified as Green List (High Evidence).
Construction of “Undiagnosed Metabolic Disorders” (UDM) panel • The 614 genes from the neurometabolic gene panel (PMID: 27604308) added • Green genes downloaded from V1 metabolic panels (Cerebral folate deficiency, Congenital disorders of glycosylation, Hyperammonaemia, Ketotic hypoglycaemia, Mitochondrial disorders, Mucopolysaccharideosis, Gaucher, Fabry, Peroxisomal disorders), sources replaced with "Expert review green", then loaded as a review onto UDM panel, resulting in 367 green genes and 333 red (therefore 86 new green genes included from the additional metabolic panels that weren't previously on the UDM panel) • Downloaded green genes from all panels. Removed genes from none V1 panels. Removed genes from the metabolic panels mentioned above. Compared the remaining genes with the red genes from UDM panel. Loaded as an "Expert review Amber" review to the overlapping genes, (the panel name where the genes came from was used as the phenotype) • Used variant information from PMID 27604308 to review the genes on this panel • Reviewed genes on UDM panel with genes from Emory "Inherited Metabolic Disorders: Sequencing Panel" and UKGTN “Inborn Errors of Metabolism 226 panel”, changing status where appropriate, added 14 UKGTN genes that had not be listed before • Review 10 red genes that had not previously been reviewed, 4/10 were reclassified as green • Review the remaining 145 red genes that had not previously been reviewed (shared between reviewers EM, RF, LD, AT, HB, ON & SL), resulting in 60 green, 11 amber, 70 red, 4 I don’t know reviews) • Reviewed genes from PMID: 24816252 as a publication to genes found in the Inborn error or metabolism Genes metabolomics GWAS paper (figure 5). 2 new genes added
