Undiagnosed metabolic disorders
Gene: DBHComment on phenotypes: formating issue
Created: 25 May 2017, 8:25 a.m.
Treatable tag added: Medical therapy (eg, droxidopa) can effectively treat manifestations such as orthostatic hypotension
Surveillance of renal function should be instituted
For untreated individuals, circumstances such as vigorous exercise, hot environements, and dehydration should be avoided
In infantile-onset disease, awareness of hypotension, hypothermia, and hypoglycemia may be beneficialCreated: 28 Feb 2017, 11:14 a.m.
3 variants reported in at least 4 unrelated casesCreated: 23 Feb 2017, 5:13 p.m.
Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal
Phenotypes
Dopamine beta-hydroxylase deficiency (Disorders of neurotransmitter metabolism, biogenic amines)
Publications
Phenotypes for DBH were set to Dopamine beta-hydroxylase deficiency 223360 AR; [Dopamine-beta-hydroxylase activity levels, plasma]; Dopamine beta-hydroxylase deficiency (Disorders of neurotransmitter metabolism, biogenic amines)
This gene 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
