CC   -!- DISEASE: Central hypoventilation syndrome, congenital, 3 (CCHS3)
CC       [MIM:619483]: A form of congenital central hypoventilation syndrome, a
CC       rare disorder characterized by abnormal control of respiration in the
CC       absence of neuromuscular, lung or cardiac disease, or an identifiable
CC       brainstem lesion. CCHS3 is an autosomal recessive, neonatal form
CC       characterized by slow and shallow breathing due to a deficiency in
CC       autonomic control of respiration. Affected individuals present with
CC       respiratory insufficiency and absence of the hypercapnic reflex that
CC       stimulates breathing. Additional features include gastrointestinal
CC       problems, poor heat tolerance and paroxysmal hypertension.
CC       {ECO:0000269|PubMed:30487221}. Note=The disease may be caused by
CC       variants affecting the gene represented in this entry.
