MalaCards based summary: Joubert Syndrome 1, also known as joubert syndrome, is related to joubert syndrome 14 and joubert syndrome 21, and has symptoms including oculomotor apraxia, muscular hypotonia and apnea. An important gene associated with Joubert Syndrome 1 is INPP5E (inositol polyphosphate-5-phosphatase, 72 kDa). Affiliated tissues include brain, eye and cerebellum, and related mouse phenotypes are liver/biliary system and digestive/alimentary.

Disease Ontology:8 An autosomal recessive disease that is characterized by congenital malformation of the brainstem and agenesis or hypoplasia of the cerebellar vermis leading to an abnormal respiratory pattern, nystagmus, hypotonia, ataxia, and delay in achieving motor milestones resulting from dysfunction of ciliary proteins (ciliopathy).

Genetics Home Reference:21 Joubert syndrome is a disorder that affects many parts of the body. The signs and symptoms of this condition vary among affected individuals, even among members of the same family.

NIH Rare Diseases:42 Joubert syndrome is a disorder that affects many parts of the body.  the signs and symptoms vary among affected individuals, even among members of the same family.  the hallmark feature of joubert syndrome is a brain abnormality called the molar tooth sign, which can be seen on brain imaging studies such as magnetic resonance imaging (mri).  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. last updated: 8/19/2011
