In their randomized controlled trial (RCT) investigating the effects of GH therapy on lung function, sleep, behavior, and cognition in children with PWS [25], Haqq et al. found notable improvement in lung function and sleep quality, with improved spirometric parameters and a trend towards fewer occurrences and shorter duration of hypopnea and apnea events after rhGH therapy [25]. The gene discussed is GH1; the disease is Prader-Willi syndrome.
