Moebius syndrome

A facial nerve disease characterized by congenital, uni- or bilateral, non-progressive facial weakness and limited abduction of the eye(s).

Muenke Syndrome

A craniosyntosis characterized by autosomal dominant inheritance, uni- or bicoronal synostosis, macrocephaly, midfacial hypoplasia, and developmental delay that has_material_basis_in a pro250 to agr (P250R) heterozygous mutation in the FGFR3 gene on chromosome 4p16.3.

humeroradial synostosis

A synostosis that is characterized by uni- or bilateral fusion of the humerus and radius bones at the elbow level, with or without associated ulnar and carpal/metacarpal deficiency, leading to loss of elbow motion and, in many cases, functional arm incapacity.

autosomal dominant thrombophilia due to protein S deficiency

A protein S deficiency characterized by reduced serum protein S levels and recurrent venous thrombosis that has_material_basis_in heterozygous mutation in the PROS1 gene on chromosome 3q11.1.

sickle cell disease

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).

Charcot-Marie-Tooth disease intermediate type

A Charcot-Marie-Tooth disease characterized by motor conduction velocities above and below 38 m/s.

autosomal recessive thrombophilia due to protein S deficiency

A protein S deficiency characterized by thrombosis and secondary hemorrhage usually beginning in early infancy that has_material_basis_in homozygous or compound heterozygous mutation in the PROS1 gene on chromosome 3q11.1.

refractive amblyopia

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

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

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.
