- developmental and epileptic encephalopathy 9 [DOID:0060848]
A developmental and epileptic encephalopathy characterized by seizure onset in infancy and mild to severe intellectual impairment in females that has_material_basis_in heterozygous mutation in the gene encoding protocadherin-19 (PCDH19) on chromosome Xq22.
- embryonal tumor with multilayered rosettes [DOID:0081286]
A central nervous system embryonal tumor that is characterized by the presence of multilayered rosette formation and typically the presence of amplification of the C19MC region on chromosome 19 (19q13.42) or rarely a DICER1 mutation.
- critical COVID-19 [DOID:0081012]
A COVID-19 that is characterized by the criteria for acute respiratory distress syndrome (ARDS), sepsis, septic shock, or other conditions that would normally require the provision of life sustaining therapies such as mechanical ventilation (invasive or non-invasive) or vasopressor therapy.
- thiamine-responsive megaloblastic anemia syndrome [DOID:0090117]
A syndrome that is characterized by megaloblastic anemia, non-type I diabetes mellitus, and sensorineural deafness where the anemia and sometimes diabetes is repsonsive to high doses of thiamine, and that has_material_basis_in homozygous mutation in the solute carrier family 19 member 2 (SLC19A2) gene on chromosome 1q24.
- CIC-rearranged sarcoma [DOID:0081250]
An EWSERI-negative small round cell tumor that is characterized by a recurrent translocation involving the CIC gene on chromosome 19 and either DUX4 gene on chromosome 4 or DUX4L gene on chromosome 10. The translocation results in either CIC-DUX4, t(4;19)(q35;q13) or CIC-DUX4L, t(10;19)(q26;q13) fusions.
- multisystem inflammatory syndrome in children [DOID:0080711]
A Coronavirus infectious disease that is characterized by a patient aged less than 21 years with fever, laboratory evidence of inflammation, and evidence of clinically severe illness requiring hospitalization, with multisystem organ involvement (cardiovascular, dermatologic, gastrointestinal, hematologic, neurologic, renal, or respiratory) who tested positive for SARS-CoV-2 or had exposure to COVID-19.
- long COVID [DOID:0080848]
A Coronavirus infectious disease that is characterized by long-term persistent and fluctuating symptoms, in individuals with COVID-19, persisting beyond three to four weeks, including the loss of the ability to smell and taste, breathlessness, fatigue, difficulty in breathing, difficulty concentrating, memory loss, confusion, headache, heart palpitations, chest pain, pain with deep breaths, dizziness, and tachycardia.
