Abstract :
Joubert syndrome (JS) is a rare autosomal recessive central nervous system malformation characterized by hypoplasia of the cerebellar vermis,
hypotonia and abnormal psychomotor development, along with altered respiratory pattern and various ophthalmologic features.
Here, we describe three children with Joubert syndrome in a family that had almost similar presentations, including ataxia, developmental delay, mental retardation and ocular disorders.
Prevalence of Joubert syndrome is about 1 in 100,000 live birth. It may be accompanied by other organs’ disorders. The molar tooth sign is pathognomonic for joubert syndrome that is ascertained by brain MRI.
