Introduction: Laron Syndrome (LS) or primary growth hormone (GH) insensitivity is an autosomal recessive disorder due to variants in the GH-receptor (GHR) gene or to post-receptor defects. LS prevalence is estimated 1-9/1000000. We report a case of LS with a missense variant in the GHR gene not previously described.Case: female, Turkish, was referred to our clinic for short stature. Born at term, birth ...

Introduction: McCune Albright Syndrome (MAS) is a rare disorder caused by somatic activating mutations of the GNAS gene, characterized by monostotic/polyostotic fibrous dysplasia, café au lait skin pigmentation and hyperfunctioning endocrinopathies. We report a case of MAS presenting with mild phenotypic characteristics and central precocious puberty (CPP).Case: Indian female was referred to our clinic fo...

Background: Non alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in childhood, in obese subjects and associated with insulin resistance.FOXO1 is a key regulator in insulin signalling and in intracellular adipogenesis, and is implicated in liver steatosis. We have previously identified that a group of miRNAs are involved in its epigenetic regulation.Objective and hypotheses: We aimed to assess in liver tissue and in serum whe...

Introduction: COVID-19 pandemic resulted in serious social challenges and physical and mental repercussions. In many countries, central precocious Puberty (CPP) increased dramatically but long-term data are really reduced.Aim: A retrospective evaluation of incidence and characteristics of CPP before and during COVID-19 pandemic in four Italian Paediatric Hospitals (Florence, Modena, Reggio-Emilia and Parma).<p class=...

Introduction: Aggrecanopathies are rare disorders associated with idiopathic short stature. They are caused by pathogenic variants in the ACAN gene.Case: Female, was referred to our clinic for short stature. Born at 34+3 weeks from a Thai mother and Caucasian father, birth weight was 2190g (0.14 SDS), length 45cm (0.21 SDS) and head circumference 31cm (-0.13 SDS). Pregnancy was obtained by in vitro fertilization...

Introduction: The IGSF1 gene deficiency syndrome (IDS) is an X-linked disorder involving hormonal disfunctions. We report a case of Central Hypothyroidism (CH) due to a Xq26.1q26.2 microdeletion including the IGSF1 gene.Case: this boy was referred to our clinic for thyroid dysfunction. He was born at term by caesarean section due to maternal uterine myoma. Pregnancy was normal, parents were non consangu...

GH and IGF1 regulate cell proliferation, differentiation and apoptosis playing a key role in growth, and leading to consider potential oncogenic effects of GH. To evaluate possible oncogenic risks in GHD patients who underwent GH replacement therapy, the SAGhE consortium was created. The data collected have not yielded definite conclusions and continuous surveillance is yet required. MiRNAs are regulators of gene expression, and are involved in many biological processes. We ai...

Cystic Fibrosis (CF), is due to CF-transmembrane-conductance-regulator (CFTR) loss-of-function. Significant heterogeneity exists between patients, suggesting potential epigenetic regulation, and comorbidities develop with time. MiRNAs are non-coding RNAs that act as epigenetic regulators. Although many studies have focused on the role for miRNAs in regulating CFTR gene expression, little attention has been given to how CFTR influences their expression and how this affects grow...

The growth response in patients undergoing GH treatment is variable depending both on the patient's basal conditions and on personal innate sensitivity to therapy. MicroRNAs (miRNAs) are epigenetic regulators of gene expression, and are recognised as important regulators of biological and metabolic processes. It is unknown at present whether miRNAs could be early biomarkers of response to GH treatment in a perspective of individualised medicine, and whether they could disc...

PCOS treatment in adolescence should aim at improving ovarian function, based on the pathophysiology of this condition. We previously described in cystic fibrosis and then in the PCOS an increase in HMGB1, secondary to reduced cystic fibrosis transmembrane conductance regulator (CFTR) expression in the ovary, associated with insulin resistance and inflammation that both characterize PCOS. Inositols and ALA derivatives are considered a good therapeutic option for their possible...
