Joubert Syndrome 1; Jbts1

Description

Joubert syndrome is a clinically and genetically heterogeneous group of disorders characterized by hypoplasia of the cerebellar vermis with the characteristic neuroradiologic 'molar tooth sign,' and accompanying neurologic symptoms, including dysregulation of breathing pattern and developmental delay. Other variable features include retinal dystrophy and renal anomalies (Saraiva and Baraitser, 1992; Valente et al., 2005).
