Background: IGF1 receptor (IGF1R) mutations are associated with pre- and post-natal growth retardation. We describe two monozygotic twins, one of them born small for gestational age (SGA), referred at the age 4 years and 2 months for short stature.Case presentation: The twins were born from non-consanguineous parents at 37-weeks gestational age by caesarean delivery. At birth: patient 1 had weight 2.076 kg (−2.4 SD...

Background: Cytochrome C oxidase (COX) is the fourth component of the respiratory chain. This protein is located within the internal membrane of mitochondria. COX deficiency is an inherited mitochondrial disease associated with considerable genetic and clinical variability(1). In fact, four clinical subtypes of this condition have been identified, each one with several phenotypic and genetic variants. Mitochondrial complex IV deficiency nuclear type 4 is a rar...

Introduction: Bilateral adrenal hemorrhage is a rare pathology, contrary to what happens with unilateral ones. It is more common in newborns and associated with situations of perinatal hypoxia, sepsis, traumatic births, or coagulation abnormalities. The classic triad includes jaundice, anemia, and a flank mass, which can lead to severe shock. Extensive bilateral hemorrhage is required to produce a situation of adrenal insufficiency. The diagnosis is made by im...

Introduction: X-linked hypophosphatemic rickets (XHR) is the most common form of hereditary rickets, with an estimated incidence of 1: 20.000 individuals. The main characteristic of the disease is excessive renal phosphate loss, which leads to hypophosphatemia with high phosphaturia and defective bone mineralization.XHR results from mutations in the in the PHEX gene (Phosphate Regulatory Gene with Homology for Endopeptidases located on t...

Introduction: Brown adipose tissue (BAT) secretes molecules capable of modulating systemic metabolism. Growth hormone (GH) has hyperglycemic action, produces lipolysis and increases muscle mass. However, there are no human studies on its effect on the BAT and lipidome.Aim: To evaluate the effect of GH on BAT and lipidome in small for gestational age (SGA) patients and its relationship with adherence to treatment.<p c...

Background: Silver Russell Syndrome (SRS) is characterized by pre- and postnatal growth failure, relative macrocephaly at birth, prominent forehead, feeding difficulties and body asymmetry. The diagnosis is clinical, the genetic mechanisms involved are different, in 50% of cases loss of methylation (LOM) at the paternal H19/IGF2:IG-DMR (chr11p15.5), in 10% of cases maternal uniparental disomy of chromosome 7 (UPD(7)mat), cases of maternal uniparental ...

Background: Congenital hypopituitarism (CH) genetics is highly heterogeneous. The massive use of NGS identified at least 21 desease causing genes. Not fully understood inheritance mechanism, incomplete penetrance and variable expressivity explain the complexity of phenotype-genotype correlations. To further complicate the scenario, the co-occurence of more than one desease-causing genes variants can geopardize the phenotype. Herein, we report the heterogeneous...

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: MKNR3 is a paternally expressed gene whose loss-of-function mutations cause Central precocious puberty (CPP). The precise molecular disruption produced by MKRN3 mutations remains unclear albeit protein structure suggests MKRN3 could play a role in proteasome ubiquitination. Circulating MKRN3 levels has been negatively associated to LH peak, estradiol and kisspeptin in idiopathic CPP and healthy controls. However, no literature data is available for...

Background: Adult survivors from childhood malignancy are prone to accelerated atherogenesis and cardiovascular (CV) complications. In this population reliable tools are needed to detect preclinical onset of CV disease.Aim: To assess subclinical markers of inflammation and endothelial dysfunction in young survivors from acute lymphoblastic leukemia (ALL) treated with chemotherapy without cranial irradiation (AIEOP 2000 a...
