Background: Prader-Willi syndrome is a rare genetic neurodevelopmental disorder caused by a paternal deficiency of maternally imprinted gene expression located in the chromosome 15q11-q13 region. Previous studies have demonstrated that several classes of neurodevelopmental disorders can be attributed to either over- or under-expression of specific genes that may lead to impairments in neuronal generation, differentiation, maturation and growth. Epigenetic chan...

Background: Prader–Willi syndrome (PWS) results from abnormalities in the genomic imprinting process leading to hypothalamic dysfunction with an alteration of GH secretion. PWS is associated with early morbid obesity and short stature which can be efficiently improved with GH treatment.Objective and hypotheses: Our aims were to highlight adipose tissue structural and functional impairments in young children with PWS and to study the effect of GH tre...
