CCHS PHOX2B

Disease ID
CCHS
Gene ID
PHOX2B

Disease

Name
Congenital central hypoventilation syndrome
Inheritance
Autosomal dominant
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 (adapted from Mondo)1 .
Prevalence
Incidence is 1:148000-200000 births (Estimated, may include mild/undiagnosed or be overestimated globally)2 . Rare, but reported worldwide3 .
Age of Onset(Typical)Years0  360  2
Age of Onset Details
Typical: 0-22,3 ; Range: 0-364 .

Locus

Details
Alleles of 24 repeats (and sometimes 25 repeats) correspond to delayed disease onset and/or milder phenotype; alleles above benign range (9-20 repeats) and below the pathogenic range (26-33 repeats) have uncertain significance2 .
Mechanism
LoF/GoF
Polyalanine expansion leading to loss or gain of function, dependent on altered protein product5,2 . Correlation between length and reduced transcriptional activity6 .
