Undiagnosed metabolic disordersGene: CLPB
Comment on mode of inheritance: Updated MOI from 'Biallelic' to 'Both mono- and biallelic'.
Association between biallelic variants and disease is well established, with more than 35 affected individuals reported. Recently, six unrelated individuals with de novo monoallelic missense variants in CLPB were identified (PMID: 34140661). The phenotype strongly overlapped with that observed in the recessive disease, including 3-MGA-uria in all cases.

Mode of inheritance for gene: CLPB was changed from BIALLELIC, autosomal or pseudoautosomal to BOTH monoallelic and biallelic, autosomal or pseudoautosomal
Publications for gene: CLPB were set to 25595726; 25597510; 25597511; 25650066
Phenotypes for gene: CLPB were changed from 3-methylglutaconic aciduria with the following: cataract, renal cysts and nephrocalcinosis; progressive brain atrophy, intellectual disability, congenital neutropenia, cataracts, movement disorder; cataract, neutropenia, epilepsy; congenital microcephaly and severe encephalopathy to 3-methylglutaconic aciduria, type VII, with cataracts, neurologic involvement and neutropenia, OMIM:616271
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
