Overview
RASopathies, including Noonan syndrome, involve dysmorphisms, metabolic alterations, and an unfavorable lipid profile. This study investigates lipid and glucose metabolism to improve patient care.
Description
RASopathies are a group of congenital malformative syndromes, including Noonan syndrome and related disorders, characterized by dysmorphisms, cardiac defects, skeletal anomalies, cognitive involvement, and a variable predisposition to pediatric cancers. They share dysregulation of the RAS-MAPK pathway and exhibit altered energy metabolism, with reduced adiposity and feeding difficulties. Preliminary studies suggest an unfavorable lipid profile, with low total cholesterol and HDL, varying by sex, age, and genotype. This multicenter study aims to further investigate lipid and glucose metabolism in patients with RASopathies to better define the natural history of the disease and support clinical management.
