Rapid-Onset Obesity With Hypothalamic Dysfunction, Hypoventilation, and Autonomic Dysregulation Presenting in Childhood

We provide a comprehensive description of the clinical spectrum of rapid-onset obesity with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation in terms of timing and scope of symptoms, study of candidate genes, and screening for chromosomal deletions and duplications. Negative PHOX2B sequencing results demonstrate that this entity is distinct from congenital central hypoventilation syndrome.
