Background: Joubert Syndrome (JS) is a rare genetic developmental disorder, first identified in 1969. In patients with JS, certain regions of the brain (mainly cerebellar vermis and brainstem) are underdeveloped or malformed. This can lead to impaired attention, visual, spatial, motor, language and social functional skills. JS is characterized by a host of features, many of which do not occur in every patient. Aim of the Study: To spotlight and increase awareness of clinical profile and neuroimaging findings of children with Joubert syndrome. Methods: This is a retrospective case series study of patients with JS who attended the Pediatric Neurology Clinic in Aladan and Alfarawanya Hospitals in Kuwait, from September 2007 to September 2012. Clinical and radiological data were obtained from the patient medical records. Results: Cerebellar vermis hypoplasia/aplasia and apnea were present in all patients, polydactly in 3 of 16, renal problems with cysts in 5 patients and 11 of 16 had abnormal electroretinograms (ERGs). Blood investigations of organic acids, amino acids and very-long-chain fatty acid, were normal in the all the nine patients. Conclusion: JS is a rare genetic brain malformation with association of retinal dystrophy and renal abnormalities. The retinal dystrophy may be progressive. The prognosis of patients depends mainly on the degree of brain malformation.
