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.
Term: MELAS syndrome
Accession: DOID:3687

Definition: A mitochondrial encephalomyopathy that is characterized by mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes, has_symptom myalgia, motor weakness, headaches, seizures, and stroke-like episodes with acute hemiparesis and severe headaches, and develops_from mutation in mitochondrial genes including MT-TL1, which encodes tRNA proteins.
