Early identification of monogenic obesity, a rare condition, is quite challenging for pediatricians. Src-homology-2 (SH2) B adapter protein 1 (SH2B1) is an important component in the leptin-melanocortin pathway and it is found to play an important role in leptin and insulin signaling. In humans a rare deletion of a 220-kb region on chromosome 16p11.2 encompassing approximately 9 genes, including the SH2B1 gene, is associated with a highly penetrant form of isolated severe earl...

Introduction: We report a series of three siblings, two girls and one boy, diagnosed with Central Precocious Puberty (CPP) respectively at the age of 5.66, 6.67 and 8.5 years, carrying a mutation in the gene encoding the makorin RING finger protein 3 (MKRN3), usually responsible for the development of familial CPP.Methods: We diagnosed CPP in all the patients by performing a GnRH test. We also dosed basal levels of LH, F...

Background: Next generation sequencing (NGS) has recently been proposed as a primary diagnostic tool in the work-up of children with idiopathic short stature (ISS) and born small for gestational age (SGA). The main limitation of a multi-gene approach is represented by the difficulty in the interpretation of VUS clinical significance.Aim: To identify and characterize genetic variants in a cohort of children born SGA and I...

Background: In Italy monogenic forms of hyperglycemia account for more than 6% of cases referred to pediatric diabetes clinics. In January 2019 we started a Monogenic Diabetes Clinic (MDC) with the three main aims: a) implementing a standardized pathway towards genetic testing, 2) ease the revision of complex cases, 3) implement standardized therapies for monogenic diabetes mellitus (MDM) subtypes.Methods: Type 1 diabete...
