Background: Acrodysostosis Type 2 (ACRDYS2) is a rare autosomal dominant skeletal dysplasia associated with intellectual disability and gain-of-function mutations in the phosphodiesterase type 4D gene (PDE4D) which, in turn, leads to a paucity of intracellular cAMP due to increased PDE4D activity. This increased PDE4 activity may be due to a greater existence of a mutant monomeric form of PDE4D. To date, the clinical use of PDE4 inhibitors in ACRDYS2 has been ...

Discrimination between transient and permanent congenital hypothyroidism in patients with eutopic thyroid gland

Kim Chan Jong

Introduction: Congenital hypothyroidism (CH) is diagnosed with neonatal screening and treated early in the neonatal period. Among these patients, transient congenital hypothyroidism (TCH) is included and requires re-evaluation. In this study, we aimed to identify factors that would allow discrimination between permanent and transient hypothyroidism in patients with eutopic thyroid gland.Methods: We retrospectively analyz...

Efficacy of Once-Weekly Treatment for Paediatric Growth Hormone Deficiency: A Systematic Literature Review and Indirect Treatment Comparison

Schaible Kassandra , Huelin Rachel , Loftus Jane , Nijher Monica , Neupane Binod , Cappelleri Joseph , Fahrbach Kyle

Introduction: Paediatric growth hormone deficiency (pGHD) is a rare disorder characterised by inadequate secretion of growth hormone (GH). Daily injections of somatropin, a recombinant human GH, is the standard of care. Once-weekly GH treatments have been recently developed, but no direct comparisons have been published. This study examined the clinical efficacy of the available once-weekly treatments vs. daily treatment for pGHD via a systematic literature re...

Adrenocortical Tumours in Children – A Case Series

Hua Chan Si , Farhad Vasanwala Rashida

Background: Paediatric adrenocortical tumours (ACT) are rare and typically present with virilising symptoms and signs which can be similar to other virilising conditions such as congenital adrenal hyperplasia.Case description: We describe three cases of ACT diagnosed and managed at our institution over the past 10 years. The three girls presented with symptoms of virilisation. The mean interval between first symptoms and diagnosis was 19.6 months (rangin...

A novel mutation of androgen receptor in a patient with complete androgen insensitivity syndrome

Jong Kim Chan , Hwan Chang Seong

Androgen insensitivity syndrome (AIS) is a rare genetic disease caused by mutation in the androgen receptor (AR). The AR is an essential steroid hormone receptor that plays a crucial role in male sexual differentiation and development. Mutations in the AR gene on the X chromosome cause malfunction of the AR so that a 46,XY karyotype male shows some physical characteristics of a woman or a full female phenotype. Depending on the phenotype, AIS can be classified as complete, par...

Severe Short Stature and GH Insensitivity Due to a De Novo Heterozygous STAT5B Missense Mutation

Klammt Jurgen , Neumann David , Andrew Shayne F , Drahosova Marcela , Stobbe Heike , Buckham Kyle , Rosenfeld Ron G , Pfaffle Roland , Hwa Vivian

Background: GH insensitivity is caused by disturbances of GH receptor function or inability to transduce the hormone signal. Affected children are severely growth retarded and may also present immune complications when the transducer STAT5B is defective. Only autosomal-recessive STAT5B mutations have been described to date.Clinical case: Two male 14.5 year monozygotic twins presented with heights of 131.5 cm (−5.3 SDS). Bone age of the ind...

Renal Complication of Hematuria and Proteinuria after Recombinant Human Growth Hormone Therapy in Children

Kim Chan Jong , Park Na Ri , Yang Eun Mi

Introduction: Treatment with recombinant human growth hormone (rhGH) is useful for growth failure in short stature children. But there are some reports of renal disease or complication occurring during rhGH treatment. GH and insulin-like growth factor-1 (IGF-1), together with other growth factors and cytokines, have important roles in adaptive morphological and functional changes in the kidney. This study was aimed to reveal the renal complication of hematuria...

Protein-Induced Hypoglycemia Secondary to Hyperinsulinism-Hyperammonemia (HI/HA) Syndrome: A GLUD1 Gene Mutation

D'Ambrosio Fabiola , Buchanan Ashley , Chan Jacquelin , Mantis Stelios

Introduction: Hyperinsulinism–Hyperammonemia (HI/HA) syndrome is a rare autosomal disease characterized by episodes of hypoglycemia related to consumption of high-protein containing foods or fasting with associated hyperammonemia secondary to an activating mutation in the GLUD1 gene. It often remains unrecognized until later in childhood because symptomatic episodes can be misinterpreted as epilepsy if patterns of hypoglycemia with fasting and protein-rich meals are not i...

Atypical Presentation of Six Patients with Mutations in the Side Chain Cleavage Enzyme CYP11A1

Chan Li , Huebner Angela , Spoudeas Helen , Cheetham Tim , Metherell Louise

Background: Mutations in the side chain cleavage enzyme, (CYP11A1) cause congenital adrenal insufficiency, with complete or partial 46XY sex reversal. The disorder manifests with adrenal and gonadal insufficiencies along with derangements of the renin/angiotensin system.Objective and hypotheses: To obtain a genetic diagnosis in six patients with adrenal insufficiency of unknown aetiology. Patients 1 and 2 are sisters with ACTH resistance, having...

Genetics of Familial Glucocorticoid Deficiency Over the Decades: Phenotypic Variability and Associated Features

Smith CJ , Maharaj AV , Prasad R , Hughes CR , Clark AJL , Chan LF , Metherell LA

Background: Over the last 25 years more than 410 cases with suspected Familial Glucocorticoid Deficiency (FGD) have been referred to our centre for genetic testing. All cases had low or undetectable serum cortisol paired with an elevated plasma ACTH level. Our patient cohort comprises 352 families from 30 different nationalities and ranges from neonates to patients in their eighties. Mutations in the MC2R were first discovered as causative of FGD in 1...
