Background: Disorders of Sex Development (DSD) are a rare disease often caused by complex genetic mechanisms, with a wide spectrum of clinical manifestations that lead to a continous evolution of the diagnostic classification. From 2002, In the Veneto Region, all DSD diagnoses have been collected thanks to the creation of a Registry for Rare diseases, including DSD.Material and Methods: We could retrospectively analyze t...

LHX3, a member of the LIM-homeodomain transcription factors family, regulates pituitary development in vertebrates and the maintenance of mature anterior pituitary cells. Nineteen mutations in LHX3 gene have been reported in HGMD database, in homozygous and compound heterozygous patients. The phenotype may present with pituitary dysfunction only or with syndromes involving also nervous and skeletal systems. The MRI images include aplasia or hypoplasia of pitui...

Introduction: Early identification of classic 21OH-Congenital Adrenal Hyperplasia (21OH-CAH) through newborn screening (NBS) is crucial to prevent adrenal crises, especially in males. Today 21 OH-CAH NBS is performed in 5/21 regions of Italy. This study aims to report the results of 21OH-CAH NBS in Italy from 2006 to 2019.Methods: All patients underwent a dried blood spot (DBS) test for 17OH-progesterone (17OHP) within t...

Introduction: Previous studies showed that non-obese children and adults with Prader-Willi syndrome (PWS) have a low frequency of metabolic syndrome (MetS), while obese ones have a frequency similar to that of non-PWS obese. It is known that individuals born small for gestational age (SGA) have a greater predisposition to the development of MetS. Recent neonatal percentiles of subjects with PWS (Salvatoni et al, Am J Med Genet Part A, 2019) documented...

Background: The short stature homeobox-containing (SHOX) gene, located in the telomeric pseudoautosomal region 1 (PAR1) on the short arm of both sex chromosomes, is important for linear growth.Objective and hypotheses: The aim of our study was to evaluate the presence of SHOX gene deletions/point mutations in children with short stature in order to understand the role of SHOX gene in idiopathic short stature (ISS) and estimate its frequency.<p class=...

Introduction: The diagnosis of GHD requires the coexistence of anamnestic, auxological and laboratory data. The latter are burdened by the poor accuracy and adverse effects of the stimulation tests. A recent european audit (Horm Res Paediatr 2019;92(3): 150-156) on GH diagnostic reported as preferred tests in Italy Insulin tolerance test (ITT), glucagon, clonidine, arginine and Arg-GHRH. We conducted a survey to explore which of them are most used in It...
