Undiagnosed metabolic disorders
Gene: UPB1
Considerably more patients have now been identified with variants in this gene and the associated biochemical abnormalities. Whilst there are indeed clinically asymptomatic patients, this is not unusual in some inherited metabolic disorders where a spectrum of severity can exist despite clear biochemical abnormality. Most likely the patients being investigated by this panel will be clinically symptomatic and therefore if mutations are found in this gene the likelihood is they will be relevant (especially if biochemical testing concurs)Created: 21 Dec 2018, 3:49 p.m.
Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal
Publications
A number of patients (6) reported with variants however, the phenotype associated does not seem consistent, is widely variable and includes normal subjects therefore I would not include on this level of evidenceCreated: 23 Feb 2017, 5:16 p.m.
Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal
Phenotypes
Beta-ureidopropionase deficiency 613161

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
