Cognitive abilities are variable, ranging from severe intellectual deficit to normal intelligence. Neuro-ophthalmologic examination may show oculomotor apraxia.

In some cases, seizures occur. Careful examination of the face often shows a characteristic appearance: large head, prominent forehead, high rounded eyebrows, epicanthal folds, ptosis occasionally , an upturned nose with prominent nostrils, an open mouth which tends to have an oval shape early on, a 'rhomboid' appearance later, and finally can appear triangular with downturned angles , tongue protrusion and rhythmic tongue motions, and occasionally low-set and tilted ears.

Other features sometimes present in Joubert syndrome include retinal dystrophy, hepatopathy, nephronophthisis, and polydactyly.

JS is due to dysfunction of the primary, non-motile cilium found in most cells. Most of these genes encode proteins that constitute the primary cilium or the regulatory proteins and transcription factors involved in its development and function. Diagnosis is based on the main clinical features hypotonia, ataxia, development delay and oculomotor apraxia , which must be accompanied by the presence of a neuroradiological hallmark, designated as the ''molar tooth sign'' MTS on magnetic resonance imaging MRI.

MTS results from hypoplasia of the cerebellar vermis and midbrain-hindbrain malformations. Moreover the clinical distinct sign is oculomotor apraxia.

Antenatal diagnosis is feasible through genetic testing where both disease-causing mutations have been previously identified in an affected family member. Imaging studies can suggest the disease fetal ultrasonography and MRI but cannot be use to conduct any antenatal diagnosis.

Transmission is autosomal recessive. Management is symptomatic and should be multidisciplinary. Education programs, physical, occupational, and speech therapy may improve the hypotonia and reduce the delay in achieving motor milestones.

In general, the neurological disability and amaurosis are not progressive. En el neumomediastino y el neumopericardio se ve el margen superior.
