monocular esotropia

An esotropia that is characterized by an excessive convergence of the visual axes, resulting in a cross-eye appearance.

Cockayne syndrome A

A Cockayne syndrome that has_material_basis_in homozygous or compound heterozygous mutation in the gene encoding the group 8 excision repair cross-complementing protein on chromosome 5q11.

spastic diplegia

A spastic cerebral palsy that affects lower extremities resulting in tight leg and hip muscles. The legs cross at the knees, making it difficult to walk.

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.

Cockayne syndrome B

A Cockayne syndrome that is characterized by severe physical and mental retardation, microcephaly, progressive neurologic and retinal degeneration, skeletal abnormalities, gait defects, and sun sensitivity with no increased frequency of cancer, and that has_material_basis_in homozygous or compound heterozygous mutation in the gene encoding the group 6 excision repair cross-complementing protein on chromosome 10q11.

Moebius syndrome

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