Central hypoventilation syndrome, congenital, 2, and autonomic dysfunction

Summary

Congenital central hypoventilation syndrome-2 and autonomic dysfunction (CCHS2) is an autosomal recessive disorder characterized by shallow breathing and apneic spells apparent in the neonatal period. Affected infants require mechanical ventilation due to impaired ventilatory response to hypercapnia, as well as tube feeding due to poor swallowing, aspiration, and gastrointestinal dysmotility. Some patients have other features of autonomic dysfunction, including bladder dysfunction, sinus bradycardia, and temperature dysregulation. Although mild global developmental delay with learning difficulties and seizures were present in the single family reported, it was unclear if these features were related to the hypoventilation phenotype (Spielmann et al., 2017). For a discussion of genetic heterogeneity of CCHS, see CCHS1 (209880). [from OMIM]
