To read the full abstract: J Clin Invest 2018;128:960-969Mouse models for PWS are urgently needed to facilitate drug development for treatment of hyperphagia and obesity in PWS patients. Here, the authors set out to create a mouse model that better recapitulates human PWS; they chose Snord116 as the target. Snord116 comprises a cluster of noncoding RNAs (ncRNAs) on paternal chromosome 15q11.2. Deletio...
