Age at diagnosis of XLH amongst children with and without a family history: Findings from the International XLH Registry

Uday Suma , Sandilands Kerry , Williams Angela , Mughal M.Zulf

Background: X-linked hypophosphatemia (XLH) is a rare, progressive, genetic phosphate wasting disorder leading to rickets, lower limb deformities as well as short and disproportionate stature. The condition is inherited in the majority, however spontaneous mutations are reported in ≈30% of cases. Its rarity, coupled with its diverse clinical manifestations, may lead to delayed diagnosis and subsequently delayed treatment initiation. The objective of this an...

FADES: A Birth Cohort to Understand the Mechanisms Underlying Accelerated Onset of Autoimmunity in Children with Down's Syndrome

Williams Georgina , Mortimer Georgina L. , Leary Sam D. , Williams Alistair J.K. , Gillespie Kathleen M. , Hamilton - Shield Julian P.

Background and Aims: Children with Down's syndrome (DS) are at increased risk of autoimmune conditions including type 1 diabetes (T1D), coeliac and thyroid disease. We previously examined the clinical and immunogenetic characteristics of these conditions in children with DS. An earlier age-of-onset of diabetes was observed compared with children with T1D from the general population despite having decreased frequencies of the established genetic susceptibil...

Introduction: Congenital adrenal hyperplasia (CAH) is the most common genetic condition in the spectrum of differences of sex development (DSD). Surgery in DSD is a controversial topic and there is no consensus if to perform surgery, how to perform surgery, and when to perform surgery. The current study was designed to evaluate the current practice in CAH related surgical practice in girls.Patients and Methods: All cases...

Background: Brain tumours are the most frequent solid tumours during childhood. Many of these patients develop endocrine disorders.Objective: To describe our cohort of patients with primary brain tumours, followed in the Pediatric Endocrinology Unit at Hôpital Universitaire Necker–Enfants Malades, Paris, France between 2010–2015, to assess current practice and propose recommendations.Methods: Retrospective a...

Introduction: Primary brain tumors are the second most common childhood malignancies, with an increasing survival rate over the years. Late effects on puberty and fertility alter survivors’ quality of life.Methods: We included 204 patients diagnosed with a primary brain tumor before 18 years, followed in pediatric endocrinology at the University Hospital “Necker-Enfants Malades” in Paris between January 20...

Sphingosine-1-Phosphate Lyase (SGPL1) Deficiency is Associated with Mitochondrial Dysfunction

Maharaj Avinaash , Bradshaw Teisha , Williams Jack , Guran Tulay , Braslavsky Debora , Brugger Britta , Metherell Lou , Prasad Rathi

Background: Loss of function mutations in SGPL1, a key component of sphingolipid metabolism, are associated with accumulation of sphingolipid intermediates giving rise to a multisystemic disease incorporating primary adrenal insufficiency (PAI) and progressive renal and neurological disease. Sphingolipids are implicated in mitochondrial apoptosis via induction of mitochondrial outer membrane permeabilization, cytosolic release of inter-membranal cytochrome c and activ...

Early Onset Hypertension with Primary Hyperaldosteronism through Mutation in the Calcium Channel CACNA1H – Case Report

Dumitrescu Cristina , Chirita Corina , Procopiuc Camelia , Gherlan Iuliana , Olaru Maria , Lifton Richard P , Nelson-Williams Carol

Background: The genetic causes of primary hyperaldosteronism are still being discovered.Results: We present the case of a 17-years-old girl who was found by accident with severe hypertension (TA 180/100 mmHg, bilateral). Her personal history was unremarkable. Her father had hypertension and a paternal aunt had died at 55 due to a stroke. Both her sisters and mother had normal blood pressure. The cardiological examinationshowed concentric left ventricle h...

Androgen Profile Differs to Adults in Adolescent Girls with Polycystic Ovary Syndrome

Frerichs Carley , Das Urmi , Garden Ann , Williams Cara , Dharmaraj Poonam , Didi Mohammed , Ramakrishnan Renuka , Blair Jo

Background: Diagnostic criteria for polycystic ovarian syndrome (PCOS) are well established in the adult population, but may not be appropriate for adolescent girls. Clinical and/or biochemical hyperandrogenism is one important diagnostic criterion. Screening for hyperandrogenism is often restricted to measurements of testosterone in adult practice. It was our impression that this strategy would under-diagnose PCOS in our adolescent population.Objective ...

SGPL1 deficiency, a cause of 46XY DSD and adrenal insufficiency, impairs lipid metabolism and steroidogenesis in Leydig cells

Kwong RMW , Smith CJ , Williams J , Hall C , Metherell LA , Prasad R

Loss of function mutations in SGPL1 (sphingosine-1-phosphate lyase) give rise to a multisystemic syndrome with predominating features of primary adrenal insufficiency (PAI) and steroid resistant nephrotic syndrome. Retrospective analysis of our patient cohort and the wider literature also demonstrated primary gonadal insufficiency in a third of male patients with microphallus and bilateral cryptorchidism (all with concomitant adrenal disease and high mortality in infa...

A novel case of hypoglycaemia secondary to a pro-insulin processing disorder

Amin Nadia , Wark Gwen , Church David , Burling Keith , Barker Peter , Williams Gemma , O'Rahilly Stephen

Background: Hypoglycaemia in patients with a high concentration of insulin and low concentration of C-peptide can be secondary to administration of exogenous insulin. This often results in safeguarding measures, with significant consequences for the patient and family. We report a novel case of a patient with symptomatic hypoglycaemia. Initial results suggested high insulin and low C-peptide levels, but subsequent testing revealed a pro-insulin processing diso...
