Mondo Description A rare disease due to a severely impaired central autonomic control of breathing and dysfunction of the autonomous nervous system. The incidence is estimated to be at 1 of 200 000 livebirths. A heterozygous mutation of PHOX-2B gene is found in 90% of the patients. Association with a Hirschsprung's disease is observed in 16% of the cases. Despite a high mortality rate and a lifelong dependence to mechanical ventilation, the long-term outcome of CCHS should be ultimately improved by multidisciplinary and coordinated follow-up of the patients.
Uniprot Description Rare disorder characterized by abnormal control of respiration in the absence of neuromuscular or lung disease, or an identifiable brain stem lesion. A deficiency in autonomic control of respiration results in inadequate or negligible ventilatory and arousal responses to hypercapnia and hypoxemia.
Disease Ontology Description An autonomic nervous system disease characterized by reduced responsiveness of the respiratory center to carbon dioxide, diminished pupillary light responses, and other symptoms related to defects in the autonomic nervous system and that has_material_basis_in most commonly heterozygous mutation in the PHOX2B gene on chromosome 4p13 and less frequently mutations in the RET, GDNF, EDN3, BDNF, or ASCL1 genes.
