Clinical presentation Most individuals with Joubert syndrome present with hypotonia, or decreased muscle tone, in infancy, which progresses to ataxia, which is a lack of muscle control during voluntary movements, in early childhood. [news-medical.net]

A hairless, purplish-red patch is usually present in the occipital-parietal region during infancy but becomes smaller as children grow. No encephalocele is present. Hearing loss and heart defects have not been reported. Intelligence is normal. [disorders.eyes.arizona.edu]

  Abnormal eye movements. Our patient had all the clinical symptoms with the exception of breathing abnormalities which may have been overlooked. [pediatricneurosciences.com]

  In these patients, the abnormal eye movements vary and include nystagmus, strabismus, oculomotor apraxia, and vertical gaze palsy. [dovepress.com]

  Other characteristic features of the condition include episodes of unusually fast (hyperpnea) or slow (apnea) breathing in infancy, and abnormal eye movements (ocular motor apraxia). [ghr.nlm.nih.gov]

  Among the congenital ataxias, Joubert’s syndrome combines episodic abnormal eye movements and hyperpnea. Some have ocular motor apraxia or congenital fibrosis syndromes. [neuroophthalmology.ca]

Prognosis Prognosis is favorable for moderate forms of the disease. Management of patients with more severe forms should be carried out at a specialized reference centre. [orpha.net]

The prognosis for infants with this syndrome depends on whether or not the cerebellar vermis is partially developed or completely absent, as well as on the severity of other organ involvement. [news-medical.net]

In addition to these, retinal and renal dysplastic changes are seen in type II, which has a worse prognosis [ 13, 14 ]. [ispub.com]

However, the prognosis is still not fully understood and its outlook is not yet documented. [jscimedcentral.com]

The syndrome is associated with progressive worsening for kidneys, the liver and the eyes and thus require regular monitoring. [4] Prognosis [ edit ] In a sample of 19 children, a 1997 study found that 3 died before the age of 3, and 2 never learned to [en.wikipedia.org]
