A two-year old male affected by Joubert Syndrome (cerebellar vermix agenesis, mental retardation, respiratory rythm disturbs, ataxia and abnormal eye movements) is reported. A review of literature of fourteen previous cases is done. Early diagnosis of this syndrome is very important for later prognosic and genetic advice.
