Potential definition: Dihydrolipoamide dehydrogenase deficiency has_material_basis_in homozygous or compound heterozygous mutation in the HIBCH gene on chromosome 2q32.

Potential parent term: amino acid metabolic disorder

Synonyms: Beta-hydroxyisobutyryl coa deacylase deficiency, HIBCH deficiency, methacrylic aciduria; methacrylic acid toxicity; valine metabolic defect; HIBCHD

ClinVar search term: hibch AND (1[VARLEN]:1000[VARLEN] AND "single gene"[Properties])

Hi @vjenkinsFB,

Thank you for your request. I have implemented the additions discussed, and they will be reflected in the next Disease Ontology Release.

Have a great day!
