- 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).
- DNA ligase IV deficiency [DOID:0060021]
A combined T cell and B cell immunodeficiency that has_material_basis_in a mutation in the LIG4 gene, a DNA ligase, encoding a protein essential for V(D)J recombination and DNA double-strand break (DSB) repair through nonhomologous end joining (NHEJ). Patients present with immunodeficiency and developmental and growth delay.
- 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).
- immunodeficiency 107 [DOID:0061076]
A primary immunodeficiency disease that is characterized by the development of invasive and severe life-threatening infections with S. aureus affecting the skin and/or lungs and that has_material_basis_in heterozygous mutation in the OTULIN gene on chromosome 5p15.
- 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.
