Medical and Biotech [MESH] Definitions

Autosomal recessive hereditary disorders characterized by congenital SENSORINEURAL HEARING LOSS and RETINITIS PIGMENTOSA. Genetically and symptomatically heterogeneous, clinical classes include type I, type II, and type III. Their severity, age of onset of retinitis pigmentosa and the degree of vestibular dysfunction are variable.

Infection of the retina by cytomegalovirus characterized by retinal necrosis, hemorrhage, vessel sheathing, and retinal edema. Cytomegalovirus retinitis is a major opportunistic infection in AIDS patients and can cause blindness.

Mild to fulminant necrotizing vaso-occlusive retinitis associated with a high incidence of retinal detachment and poor vision outcome.

A receptor tyrosine kinase that transduces signals from EXTRACELLULAR MATRIX to the CYTOPLASM by binding ligands such as GALECTIN 3. It regulates many physiologic processes that include cell survival, migration, differentiation, and PHAGOCYTOSIS of apoptotic cells and ROD PHOTORECEPTORS in the RETINAL PIGMENT EPITHELIUM. Mutations in the MERTK gene are associated with type 38 RETINITIS PIGMENTOSA; it also plays a critical role as an inhibitor of TOLL-LIKE RECEPTORS signaling.

Rare autosomal recessive disease characterized by multiple organ dysfunction. The key clinical features include retinal degeneration (NYSTAGMUS, PATHOLOGIC; RETINITIS PIGMENTOSA; and eventual blindness), childhood obesity, sensorineural hearing loss, and normal mental development. Endocrinologic complications include TYPE 2 DIABETES MELLITUS; HYPERINSULINEMIA; ACANTHOSIS NIGRICANS; HYPOTHYROIDISM; and progressive renal and hepatic failures. The disease is caused by mutations in the ALMS1 gene.
