A rare genetic disease with characteristics of congenital severe to profound deafness with no evidence of vestibular dysfunction, associated with sinoatrial node dysfunction with pronounced bradycardia and increased variability of heart rate at rest and episodic syncopes that may be triggered by enhanced physical activity and stress. There is evidence this disease is caused by homozygous mutation in the CACNA1D gene on chromosome 3p21.
