Congenital Central Hypoventilation Syndrome (CCHS) is most commonly referred to by its acronym, CCHS, and is historically known as "Ondine’s Curse." While medical literature may occasionally use terms like Primary Alveolar Hypoventilation, Congenital Central Hypoventilation Syndrome is the modern, clinically preferred term that accurately describes the neurological failure to regulate autonomic breathing. What are the common synonyms and historical names for CCHS? The medical nomenclature for Congenital Central Hypoventilation Syndrome has evolved significantly over time. The most famous historical name is "Ondine’s Curse," a reference to a mythological water nymph whose unfaithful lover was cursed to lose all automatic bodily functions, including breathing, if he ever fell asleep.

Congenital Central Hypoventilation Syndrome (CCHS) is most commonly referred to by its acronym, CCHS, and is historically known as "Ondine’s Curse."

What are the common synonyms and historical names for CCHS?
The medical nomenclature for Congenital Central Hypoventilation Syndrome has evolved significantly over time. The most famous historical name is "Ondine’s Curse," a reference to a mythological water nymph whose unfaithful lover was cursed to lose all automatic bodily functions, including breathing, if he ever fell asleep. While this term is still recognized, it is increasingly discouraged in professional settings as it is considered imprecise and potentially stigmatizing. Other terms that may appear in older medical records or international literature include:
- Primary Alveolar Hypoventilation
- Central Alveolar Hypoventilation
- Congenital Failure of Automatic Control of Breathing
- Ondine-Hirschsprung Syndrome (when associated with Hirschsprung disease)
Why does Congenital Central Hypoventilation Syndrome have so many names?
The variety of names for Congenital Central Hypoventilation Syndrome stems from the medical community’s evolving understanding of the condition's underlying pathology. Early descriptions focused purely on the clinical observation of patients who stopped breathing during sleep. As researchers identified the PHOX2B gene mutation as the primary driver, the name shifted toward a more descriptive, physiological definition. Furthermore, because Congenital Central Hypoventilation Syndrome frequently presents with other autonomic nervous system issues—such as Hirschsprung disease or tumors of neural crest origin—various names were historically coined to describe these specific clinical clusters before the genetic link was fully understood.
How is Congenital Central Hypoventilation Syndrome classified officially?
In modern medical practice, clinicians and researchers rely on standardized classification systems to ensure diagnostic accuracy. Using the current, preferred name, Congenital Central Hypoventilation Syndrome is categorized by the following major international databases:
- Orphanet: Listed under ORPHA176, specifically identifying it as a rare genetic respiratory disease.
- OMIM (Online Mendelian Inheritance in Man): Identified as #209880, documenting the central role of the PHOX2B gene.
- ICD-10/11: Often coded under G47.3 (Sleep apnea) or specific congenital malformation codes, though clinical experts prefer the precise terminology of CCHS to ensure proper care coordination.
Why is the term Congenital Central Hypoventilation Syndrome preferred?
Medical professionals currently prefer Congenital Central Hypoventilation Syndrome because it is clinically precise and descriptive. It highlights that the condition is present from birth ("congenital"), originates in the central nervous system ("central"), and involves a failure to maintain adequate ventilation ("hypoventilation"). Using this specific terminology helps 94 members of the DiseaseMaps.org community and other patients worldwide communicate effectively with multidisciplinary teams, including pulmonologists, neurologists, and geneticists, ensuring that the diagnosis is not confused with obstructive sleep apnea or other respiratory disorders.
Next steps
- Consult with a specialized pulmonologist or a neurologist who has experience with autonomic nervous system disorders.
- Request genetic counseling to understand the PHOX2B mutation status for your family.
