Introduction: Germline mutations in Phosphatase and tensin homolog (PTEN) gene (chromosome 10q23) lead to PTEN Hamartoma Tumor Syndrome (PHTS), which includes Cowden syndrome. PTEN encodes a tumor suppressor protein that is a negative regulator of PI3K – Akt signaling pathway, taking part in multiple biological processes, including cellular cycle and regulation of metabolism.Materials and Methods:...

Background: Endocrine disorders associated with tall stature in childhood are frequently evaluated by Pediatric Endocrinologists. The most common non-endocrine genetic cause of tall stature, Marfan syndrome, is a rare autosomal dominant genetic condition of the connective tissue, which presents with specific dysmorphic features, including thin physique, long extremities and normal growth rate. Little is known regarding the association of Marfan syndrome with o...

Introduction: Maturity Onset Diabetes of the Young (MODY) constitutes a genetically and clinically heterogeneous type of Monogenic Diabetes (MD), characterized by early onset of hyperglycemia, autosomal dominant inheritance and defect in β-cell insulin secretion. To date, 14 different MODY subtypes have been reported, each one with a distinct genetic etiology.Materials and Methods: We designed a NGS TGP of seven ...

Normocalcemic primary hyperparathyroidism (NPHPT) has been recognized as a variant of primary hyperparathyroidism (PHPT) and it is characterized by elevated PTH with persistently normal concentrations of albumin-adjusted total and ionized calcium. It is related to increased risk in development of osteopenia/osteoporosis as well of parathyroid adenoma and hypercalcemia/hypercalciuria. In order to identify biochemical disorders of PTH in normocalcemic children we performed in al...

Aim: To study the clinical profile of Neonatal Diabetes Mellitus (NDM) at our centreObjectives: 1. To study follow-up data on growth, glycemic control2. To review genetic analysisIntroduction: NDM is rare and occurs at a frequency of 1:1,00,000. There is scarce literature on follow up of these patients although genetic data is well established (1). Developing...

Introduction: Hypomethylation at the imprinting control region 2 (IC2) on chromosome 11p15.5 is the commonest identifiable cause of Beckwith-Wiedemann Syndrome (BWS). IC2 is located in KCNQ1 intron 10 and is associated with Long QT syndrome (LQTS). A recent consensus statement on BWS1 recommends annual cardiac evaluation with electrocardiogram (ECG) in these patients. The natural history of LQTS secondary to hypomethylation at IC2 in BWS is...

Purpose: Disorders of sex development (DSD) have been linked with gene defects that lead to gonadal dysgenesis. Herein, we aimed at identifying the genetic cause of gonadal dysgenesis in a patient with primary amenorrhoea and 46,XY karyotype from a consanguineous family.Methods and Results: Whole exome sequencing (WES) was performed and revealed in homozygosity the rare and only once reported p.Arg164Pro missense mutatio...

Introduction: Primary Generalized Glucocorticoid Resistance or Chrousos syndrome (CS) is a rare sporadic or familial disorder characterized by generalized, partial tissue insensitivity to glucocorticoids. Mutations of the NR3C1 gene, which encodes the human glucocorticoid receptor, have been identified in many but not all patients with CS.Objective: To identify novel genes related to CS in patients without NR3C1 gene mutations.<p cl...

Background: Third generation aromatase inhibitors (AI) have never been used as monotherapy to increase predicted adult height (PAH) in girls. Our previously published GAIL study (J Endocrinol Invest. 2016 Apr;39(4):439–46) has shown that the combination of anastrozole to an LHRH analogue for 24 months is safe and effective in ameliorating PAH in girls with early puberty +1.21 SDS (+7.51 cm) compared to inhibition of puberty alone +0.31 SDS (+1.92 cm), P=...

Context: The early activation of adrenal zona reticularis, denoted by increased circulating levels of adrenal androgens before the age of eight years in girls is called premature adrenarche (PA), while the concomitant appearance of pubic hair is termed premature pubarche (PP). Girls with PA-PP display an unfavorable metabolic, hormonal and psychologic profile, compared to their normal peers and are also at an increased risk of developing polycystic ovary syndrome (PCO...
