Short answer · Medically reviewed summary · Last updated: 2026-04-07
Congenital Central Hypoventilation Syndrome (CCHS) is primarily classified under the ICD-10 code G47.35 (Congenital central alveolar hypoventilation syndrome). While the older ICD-9-CM system categorized this condition under 770.81 (Primary apnea of newborn), it is important to note that these codes are used for administrative and billing purposes rather than clinical diagnostic criteria. What exactly is Congenital Central Hypoventilation Syndrome? Congenital Central Hypoventilation Syndrome is a rare, life-long disorder of the autonomic nervous system where the brain fails to signal the body to breathe automatically, particularly during sleep.

What exactly is Congenital Central Hypoventilation Syndrome?
Congenital Central Hypoventilation Syndrome is a rare, life-long disorder of the autonomic nervous system where the brain fails to signal the body to breathe automatically, particularly during sleep. Individuals with Congenital Central Hypoventilation Syndrome experience a lack of sensitivity to carbon dioxide and low oxygen levels, necessitating lifelong ventilatory support. Within the DiseaseMaps.org community, 94 people with Congenital Central Hypoventilation Syndrome have connected to share their experiences, highlighting the importance of specialized management for this complex condition.
What causes Congenital Central Hypoventilation Syndrome?
The vast majority of cases of Congenital Central Hypoventilation Syndrome are caused by a mutation in the PHOX2B gene. This gene is critical for the development of the autonomic nervous system. Most individuals carry a polyalanine expansion mutation, where the length of the expansion correlates with the severity of the symptoms. Understanding the genetic basis of Congenital Central Hypoventilation Syndrome is essential for family planning and clinical management, as it allows for precise genetic counseling regarding the risk of transmission to offspring.
How is Congenital Central Hypoventilation Syndrome managed?
Management of Congenital Central Hypoventilation Syndrome is multidisciplinary and focused on ensuring adequate gas exchange. Because the autonomic nervous system is impaired, patients require comprehensive care to address both respiratory and non-respiratory challenges. Common management strategies include:
- Ventilatory Support: Use of positive pressure ventilation or diaphragm pacers to ensure breathing during sleep and, in some cases, while awake.
- Cardiac Monitoring: Regular evaluation for autonomic dysregulation, which may include heart rate variability or rhythm disturbances.
- Gastrointestinal Support: Management of Hirschsprung disease or other motility issues associated with the PHOX2B mutation.
- Neurodevelopmental Screening: Ongoing assessments to support cognitive and motor development in pediatric patients.
Is there support for families living with this condition?
Living with Congenital Central Hypoventilation Syndrome presents significant emotional and logistical challenges for both patients and caregivers. The constant need for vigilance regarding respiratory status can lead to "caregiver burnout." Connecting with others who understand the unique daily rhythm of life with Congenital Central Hypoventilation Syndrome is vital. Peer support, such as the network found at DiseaseMaps.org, provides a space to share practical tips on equipment management and emotional coping strategies.
Next steps
- Consult with a specialized pulmonologist or a center of excellence that focuses on Congenital Central Hypoventilation Syndrome.
- Seek a referral to a clinical geneticist to confirm the PHOX2B mutation status and discuss family implications.
- Join a dedicated patient advocacy group to access the latest clinical trial information and peer support.
- Engage with the 94 members of the DiseaseMaps.org community to share experiences and build a support network.
