Background: In our center for adults with rare genetic syndromes, we see adolescents and young adults with overgrowth syndromes, among others. In our 'general endocrinology' outpatient clinic, we also see patients with overgrowth, but in these cases the overgrowth is due to excess of growth hormone (GH). Our clinical impression is that the differentiation between the two is often challenging. Therefore, we believe it is important to emphasize the dif...

The underlying mechanism for this switch may involve hyperghrelinemia, but only poor data exists regarding levels of acylated ghrelin (AG), unacylated ghrelin (UAG), and the AG/UAG ratio in PWS.Objective and hypotheses: To investigate plasma levels of AG and UAG in PWS, compare...
