Joubert Syndrome with Oral-Facial-Digital Defect ({JS}-{OFD}): A Brief Overview on Clinics and Genetics

Joubert's syndrome with digital facial oral defects represents a rare subgroup of Joubert's syndrome with related disorders. There are 11 forms of oral-facial-digital syndromes and are characterized by having neurological signs of JS associated with orofacial anomalies and often polydactyly. The most severe variant is the OFD type VI (Varadi-Papp syndrome) in which there are tongue hamartomas, multiple frenula, midline notch of the upper lip, mesoaxial polydactyly, and hypothalamic hamartomas. Treatments are symptomatic and supportive with reconstructive surgery for correctable malformation and physical therapy, occupational therapy, speech therapy, and infant stimulation for mental delay.
