Background: McCune-albright syndrome is clasiically defined by the clinical triad of fibroud dysplasia of bone (FD), café-au-lait spots and precocious puberty. It is a rare disease with variable presentation caused by somatic (non-germline) gain of function mutation in GNAS gene. It can affects both endocrine and non-endocrine tissue. In addition to precocious puberty, other hyperfunctioning endocrinopathies may be involved including hyperthyroidism, growth excess, cushin...

Background: Glycogen-storage disease type VI (GSD VI) is an autosomal recessive disorder due to deficiency of the liver isoform of phosphorylase resulting in abnormal accumulation of glycogen. Patients typically present in early childhood with growth retardation, hepatomegaly, hypoglycaemia and ketosis. Ketotic hypoglycaemia is a relatively common diagnosis (of exclusion) in children presenting with hypoglycaemia.Case: A 3-year-old girl presented with an...

Introduction: Congenital hyperinsulinism (CHI) is a rare genetic disorder that is characterised by persistent hypoglycaemia in infants and children. We are reporting a rare case of diffuse CHI who was also found to have hypopituitarism and several other congenital anomalies. A similar association has not been reported in literature.Case: A female baby was born at 42 weeks gestation with a birth weight of 4.185 kg (1.72SDS). She suffered shoulder dystocia...

Introduction: Turner’s syndrome (TS) is caused by an abnormality of one of the X chromosomes. Short stature or slow growth is one of the first manifestations of TS and it is recommended that GH therapy should be initiated as soon as it becomes apparent that affected girls are not growing normally to optimise final adult height. Idiopathic intracranial hypertension (IIH) is a well-known side effect of GH therapy, and it has also been reported in girls with TS with or witho...

Background: Congenital hyperinsulinism in infancy (CHI) is the most frequent cause of persistent hypoglycemia in infants. The most common and severe form of monogenic CHI is caused by inactivating mutations in ABCC8 and KCNJ11 genes located on chromosome 11p15.1. On the ABCC8 gene; previous studies have shown that mutations were reported to be mostly localized in exon 28. There is no sufficient research in Egyptian population about different mutations in conge...

Background: The melanocortin-4 receptor (MC4R) pathway is a key regulator of energy balance and satiety. Variants in genes upstream of MC4R encoding leptin receptor (LEPR), proopiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1(PCSK1) and those involved in Bardet-Biedl syndrome (BBS) can impair MC4R pathway signaling. Clinically, these variants are characterized by hyperphagia (Pathologic insatiable hunger) and early-onset, severe obesity. E...

Background: Numerous studies focused on the association between hypospadias and Endocrine Disrupting Chemicals (EDC) exposures. The wide variability of phenotypes included in these studies, the absence of comparison groups representative of the populations and the absence of concomitant genetic testing to rule out another cause make the results questionable.Objective and hypotheses: We performed a prospective phenotype-specific analysis of patients with ...

Silver-Russell syndrome (SRS) is a rare heterogeneous syndrome associated with severe prenatal and postnatal growth retardation.Context: There is little information on puberty onset and bone age trend in children with SRS.Study Design and partecipants: Retrospective observational study, including patients with a confirmed diagnosis of SRS divided in 2 molecular groups [ 11p15 loss of methylation, (...

Background: Osteogenesis imperfecta / Ehlers–Danlos (OI/EDS) overlap syndrome is a rare and recently described disorder of connective tissue, characterized by mutation of COL1A1 (17q21.33) or COL1A2 (7q21.3) genes, involved in alpha-1 and alpha-2 chains of type 1 collagen synthesis. Patients with OI/EDS overlap syndrome could show a phenotype characterized by features of both osteogenesis imperfecta (bone fragility, long bone fractures, blue sclerae, sho...

Achondroplasia is a rare genetic condition caused by a recurrent pathogenetic variant in the FGFR3 gene resulting in short limb skeletal dysplasia. Due to the wide-ranging anomalies associated with achondroplasia (both peculiar clinical features and complications), a multidisciplinary team is often required for ongoing care, although the nature of specialists involved differs among countries. Despite a European consensus on principles for the management of achondropla...
