It is possible that the main title of the report Congenital Central Hypoventilation Syndrome is not the name you expected.
Congenital central hypoventilation syndrome (CCHS) is a rare lifelong and life-threatening disorder. CCHS affects the central and autonomic nervous system which controls many of the automatic functions in the body such as heart rate, blood pressure, sensing of oxygen and carbon dioxide levels in the blood, temperature, bowel and bladder control, and more. The most recognized symptom of CCHS is the inability to control breathing that varies in severity, resulting in the need for life-long ventilatory support during sleep in some patients or all the time in others. There are estimated to be 1000 – 1200 cases of CCHS world-wide. CCHS affects males and females equally. Currently, there is no cure for CCHS.
The underlying cause of CCHS is mutation in the PHOX2B gene. Most children with CCHS have mutations of the PHOX2B gene called poly-alanine repeat expansion mutations (PARMs). Some children with CCHS have different mutations in the PHOX2B gene not related to PARMs called non-poly-alanine repeat expansion mutations (NPARMs). Both PARMs and NPARMs lead to impaired function of the PHOX2B protein. See the Causes section for more information.
