Background: In infants, less than 1-year JGCT is extremely rare, with very few reported cases in the literature.Case Report: This 9-month old girl, presented with a day history of bloody vaginal secretions, with an increase in breast size bilaterally 2 months before presentation and growth of fine hair in the genital area. She had no skin hyperpigmentation, no skeletal abnormalities, and no dysmorphic features. On examination, the girl had no dysmorphic ...

Preterm babies born to non-diabetic mothers (INDM) who experience significant hypoglycemia may have postnatal growth abnormalities. This study evaluated the growth pattern from birth to the age of 2 years of 40 INDM who were born at or near term with significant hypoglycemia. Anthropometric measures (z scores) from birth, 2,4.6,12,18 and 2 years were measured in 40 INDM who presented with significant neonatal hypoglycemia (plasma value less than 20-25 mg/dl (1.1-1.4 mmol/l) th...

Background and Aims: Congenital hyperinsulinism (HI) is the most frequent cause of severe, persistent hypoglycemia in newborn babies and children. The disease may occur in isolation or can present as part of a syndrome. Routine screening of the known etiological genes (n = >20) identifies a disease-causing mutation in 40-50% of all cases. An accurate and timely genetic diagnosis is clinically important for all individuals as understanding the unde...

Background: Dual-specificity tyrosine phosphorylation-regulated kinase 1B (DYRK1B) is a nutrient-sensing protein that suppresses the RAS–RAF–MEK pathway and is known to have a role in glucose uptake and glycolysis. The expression of DYRK1B increases during adipogenic differentiation suggesting an important role in adipogenesis. Mutations in DYRK1B have been described in three Iranian families and five Caucasian patients w...

Background: The leptin-melanocortin pathway is pivotal in appetite and energy homeostasis. Pathogenic variants in genes involved in this pathway lead to severe early-onset monogenic obesity (MO). The MC4R gene plays a central role in the leptin-melanocortin, and variants predominantly heterozygous in this gene, are the most common cause of MO. We identified a novel heterozygous variant c.802T>C p.Tyr268His in the MC4R gene in two unrelated patients with mor...

Introduction: Kenny-Caffey syndrome is a rare syndrome which is a primary bone dysplasia syndrome consisting of growth retardation with proportionately short stature, cortical thickening and medullary stenosis of the long bones, hypocalcemia from congenital hypoparathyroidism, and facial dysmorphism such as a prominent forehead, microphthalmia, and micrognathia. We report 13 years old with Kenny caffe syndrome who found to have a family history of the same pre...

Background: PHA is a rare, but life threatening condition, that usually presents with impressive hyperkalemia. It can be initially missed as congenital adrenal hyperplasia (CAH). We present a series of these patients to increase the awareness of treating physicians about misdiagnosis and pitfalls in management.Case Report: We admitted 4 cases in our institution between 2017-2021. Case one, three and four were all 7 days ...

Objectives: Diazoxide is first line treatment for hypoglycaemia due to hyperinsulinaemic hypoglycaemia (HH). However, the FDA has raised serious concerns regarding diazoxide-induced pulmonary hypertension (PH) in 2015. Although sporadic cases of PH have been reported, no HH cohort has been systematically characterised to understand severity and risk factors for diazoxide-induced PH.Methods: To investigate the onset, progress and associated factors in PH,...

Introduction: Congenital hyperinsulinism (CHI) is a group of rare endocrine disorders characterized by repeated episodes of hypoglycemia caused by an excessive insulin secretion from the pancreas beta cells. The etiopathogenesis, phenotype, treatment, and prognosis of individual CHI cases are variable and not completely described.Aims: To gather and describe clinical and genetic data about CHI cases diagnosed within the large EuRRECa net...

Introduction: The diagnosis and treatment of patients with rare diseases is often difficult as most clinicians do not encounter them. Therefore, centralization and collaboration between centers of expertise is necessary. European Reference Networks (ERN’s) such as RareEndoERN provide a platform for this, with one of its main thematic groups having a specific focus on rare growth and obesity disorders. Genetic obesity encompasses a heterogeneous group of c...
