RGD DISEASE ONTOLOGY - ANNOTATIONS

RGD uses the Human Disease Ontology (DO, https://disease-ontology.org/) for disease curation across species. RGD automatically downloads each new release of the ontology on a monthly basis. Some additional terms which are required for RGD's curation purposes but are not currently covered in the official version of DO have been added. As corresponding terms are added to DO, these custom terms are retired and the DO terms substituted in existing annotations and subsequently used for curation.

Definition:An amino acid metabolic disorder characterized by failure of cells to incorporate methyltetrahydrofolate into methionine, impaired methionine synthase activity in the presence of a reducing agent, and somewhat variable features that include delayed psychomotor development, hypotonia, megaloblastic anemia, homocystinuria, and hypomethioninemia that has_material_basis_in homozygous or compound heterozygous mutation in MTR on chromosome 1q43. (DO)
Synonyms:exact_synonym: homocystinuria-megaloblastic anemia due to defect in cobalamin metabolism cblG complementation type;   methylcobalamin deficiency, cblG type
 xref: GARD:3577
