Most infants with Joubert syndrome have weak muscle tone (hypotonia), episodes of unusually fast or slow breathing (hyperpnoea) and abnormal eye movements. Individuals with Joubert syndrome can have delayed development and mild to severe intellectual disabilities. Distinctive facial features are also characteristic of Joubert syndrome. Mutations in one of 10 known genes have been found in about half of all cases with Joubert syndrome and related disorders. In the remaining cases, the genetic cause is unknown. This condition typically has an autosomal recessive pattern of inheritance. Rare cases of Joubert syndrome are inherited in an X-linked recessive pattern.Joubert syndrome is a disorder that affects many parts of the body.
