P014: Unique perinatal growth phases of a Prader-Willi syndrome preclinical model
Abstract
Prader-Willi syndrome (PWS) displays neonatal failure to thrive (FTT), hypotonia, hyperphagia, obesity, endocrine and metabolic deficits, with behavioral and cognitive impairments. Early dogma considered PWS as having two developmental stages: FTT in infancy followed by hyperphagia and obesity beginning in childhood. Conversely, natural history studies now delineate multiple nutritional phases including in utero, infancy with difficulty feeding and FTT, growth and weight gain without change in appetite, followed by increasing interest in food around ages 5-13 culminating in hyperphagia.
