Objective: To evaluate the response to recombinant human GH (rhGH) treatment in NS children with short stature and previously identified mutations in the RAS/MAPK pathway genes.Methods: 23 patients with NS (17 males; 19 PTPN11, 3 RAF1 e 1 SHOC2) were daily treated with rhGH (mean rhGH dose of 47 μg/kg per day). The main outcome measures were 1st year growth velocity, change in height SDS (Noonan syndrome specifi...

Background: Noonan syndrome (NS) is a frequent autosomal dominant disorder characterized by facial dysmorphisms, heart defects, short stature and learning disabilities. It is caused by mutations in genes within the RAS/MAPK signaling pathway, thus called RASopathies. The RAS/MAPK pathway can also impact the signal transduction of hormones involved in body weight, carbohydrate, and lipid metabolism features scarcely studied only in animal models. This study aimed to describe me...
