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:A mitochondrial DNA depletion syndrome that is characterized by ophthalmoplegia, ptosis, gastrointestinal dysmotility, cachexia, peripheral neuropathy, and brain MRI changes, known as the MNGIE phenotype, and has_material_basis_in autosomal recessive homozygous or compound heterozygous mutation in the ribonucleotide reductase M2 B gene on chromosome 8q22. (DO)
Synonyms:exact_synonym: familial visceral myopathy, external ophthalmoplegia;   familial visceral myopathy, with external ophthalmoplegia;   intestinal pseudoobstruction with external ophthalmoplegia;   oculogastrointestinal muscular dystrophy
 narrow_synonym: MTDPS8B;   mitochondrial DNA depletion syndrome 8B (MNGIE type);   mitochondrial neurogastrointestinal encephalopathy syndrome, RRM2B-related
 primary_id: MESH:C536350
 alt_id: OMIM:277320;   OMIM:612075
