- sickle cell disease [DOID:0081445]
A blood protein disease that is characterized by chronic hemolytic anemia and intermittent vaso-occlusive events that result in tissue ischemia leading to acute and chronic pain as well as organ damage that can affect any organ system, resulting from the replacement of one of the beta-globin subunits in hemoglobin with atypical hemoglobin molecules called hemoglobin S which can distort red blood cells into a sickle or crescent shape. Sickle cell disease subtypes should include a detailed genotypic description for the hemoglobin molecules (e.g., Hb S/S, Hb S/C, Hb S/0-thalassemia).
- Moebius syndrome [DOID:13501]
A facial nerve disease characterized by congenital, uni- or bilateral, non-progressive facial weakness and limited abduction of the eye(s).
- refractive amblyopia [DOID:10377]
An amblyopia that is characterized by refractive error in one or both eyes that is not corrected early in childhood resulting in poor development of the visual function in the affected eye(s).
- sickle cell anemia [DOID:10923]
A sickle cell disease that is characterized by the replacement of both of the beta-globin subunits in hemoglobin with hemoglobin S, resulting in a low number of red blood cells, repeated infections, and periodic episodes of pain.
- scarlet fever [DOID:8596]
An upper respiratory tract disease described as an acute contagious disease caused by Group A bacteria of the genus Streptococcus (especially various strains of S. pyogenes) and characterized by inflammation of the nose, throat, and mouth, generalized toxemia, and a red rash.
- Ritter's disease [DOID:9063]
A commensal bacterial infectious disease that is characterized by widespread erythema, peeling, and necrosis of the skin, that is caused by a toxin produced by a bacterium of the genus Staphylococcus (S. aureus). The infection has_symptom redness of skin, has_symptom fluid-filled blister formation, has_symptom fever and has_symptom irritability.
- hereditary combined deficiency of vitamin K-dependent clotting factors [DOID:0112172]
A blood coagulation disease characterized by reduced hepatic gamma-carboxylation of glutamic acid residues of all vitamin K-dependent blood coagulation factors and the anticoagulant factors protein C and protein S resulting in a bleeding tendency that is usually reversed by oral administration of vitamin K that has_material_basis_in a heritable mutation.
