Ondine’s Curse

Ondine’s curse, or congenital central hypoventilation syndrome (CCHS) is a rare neurologic based respiratory disorder, with an incidence of 1 per 200,000 live births1. First described in 1962 by Severinghaus and Mitchell, CCHS results in alveolar hypoventilation in sleep, most prominent during slow-wave sleep and rarely in wakefulness2. Treatment requires mechanical ventilator support, often lifelong. A large series found an association with Hirschprung disease and found mutations in the PHOX2B gene in 91% of cases1. PHOX2B is a homeobox gene implicated in the development of the autonomic nervous system.
