Congenital central hypoventilation syndrome (CCHS) is a rare, but serious condition in which your baby does not breathe enough while he is asleep. In some cases, babies also do not breathe enough while they are awake. Not breathing enough can affect your baby’s brain and development.
CCHS is caused by a mutation (change) in the PHOX2B gene. In most cases, the change happens at random. The change is not anyone’s fault.
