Overview
Severe oculo-renal-cerebellar syndrome is a very rare condition that affects three main parts of the body: the eyes (oculo), the kidneys (renal), and the cerebellum — the part of the brain that controls balance and coordination (cerebellar). This condition is sometimes referred to as oculo-renal-cerebellar syndrome or ORCS. Because it affects multiple organ systems at once, it can cause a wide range of serious health problems from early in life. Children born with this syndrome typically have problems with their vision, including abnormal eye development or function. Their kidneys may not work properly, which can lead to problems filtering waste from the blood. The brain abnormalities, particularly in the cerebellum, can cause difficulties with movement, balance, and coordination. Intellectual disability and developmental delays are also commonly reported. Unfortunately, there is currently no cure for this condition. Treatment focuses on managing symptoms and supporting the affected organ systems. This may include kidney care, vision support, physical and occupational therapy, and educational support. A team of specialists is usually needed to provide the best care. Early diagnosis and a coordinated care plan can help improve quality of life for affected individuals and their families.
Key symptoms:
Vision problems or abnormal eye developmentKidney dysfunction or kidney failurePoor balance and coordinationIntellectual disabilityDevelopmental delaysAbnormal brain structure, especially in the cerebellumLow muscle tone (floppiness)Difficulty walking or movingAbnormal eye movementsProtein or blood in the urine
