Overview
Ataxia-intellectual disability-oculomotor apraxia-cerebellar cysts syndrome is an extremely rare genetic condition that affects the brain and nervous system. It is sometimes referred to by its association with mutations in the PORETTI-BOLTSHAUSER syndrome spectrum or by its Orphanet designation (ORPHA:370022). The condition is characterized by a combination of problems including ataxia (difficulty coordinating movements), intellectual disability, oculomotor apraxia (trouble moving the eyes voluntarily to look at things), and the presence of cysts in the cerebellum, which is the part of the brain that controls balance and coordination. Children with this syndrome typically show developmental delays early in life, including delays in sitting, walking, and speaking. The cerebellar cysts can be seen on brain MRI scans and are an important clue for diagnosis. Intellectual disability ranges from mild to moderate in most reported cases. The oculomotor apraxia means that affected individuals have difficulty directing their gaze, which can affect reading and daily activities. There is currently no cure for this condition. Treatment is supportive and focuses on managing symptoms. This includes physical therapy to help with balance and movement, occupational therapy for daily living skills, speech therapy for language development, and special education services. Regular follow-up with a team of specialists is important to monitor the condition and adjust care as needed.

Clinical phenotype terms (22)— hover any for plain English
Autosomal recessive
Passed on when both parents carry the same gene change; often skips generations
Infantile
Begins in infancy, roughly 1 month to 2 years old
