Background: Adrenal cortical carcinoma (ACC) in children is rare and aggressive, with the mainstay of treatment being surgical resection, although there have been recent improvements in outcomes with chemotherapy. Further characterisation of the presenting features and biochemical markers are needed to support earlier diagnosis. Refractory hypertension related to high cortisol concentrations prior to surgery, and post-operative decrease in cortisol can be chal...

Background & Objective: Recombinant human insulin like growth factor 1 (rhIGF1) therapy is the only treatment available for primary IGF1 deficiency and related disorders. However, it’s efficacy in promoting growth is controversial and needs cautious monitoring for adverse effects. The aim of this study was to determine the long-term efficacy and safety profile of rhIGF1 therapy.Methods: Retrospective review of a...

Background: The presentation of early-onset Primary Ovarian Insufficiency (EO-POI), most often with primary amenorrhea, is at one end of a spectrum spanning 40 years. The aetiology of POI is frequently unclear but next generation sequencing of varied age groups has identified several associated genetic variants. Whether girls with EO-POI are more likely to have a genetic aetiology than those with later presentations remains unknown.<stro...

Objectives: We describe 5 pedigrees with a novel phenotype including GHD associated with primary ovarian insufficiency (POI) and investigate the underlying molecular basis.Patients and Methods: 6 Turkish patients (5F, 1M) born to 5 consanguineous pedigrees with severe GHD were identified. All females had POI; the male had normal puberty. All had severe postnatal growth retardation (height -4.4 to -8.9 SDS at presentation...

Background: Thymus transplantation is undertaken for conditions associated with severe immunodeficiency. These comprise a number of genetic and syndromic associations including 22q deletion syndrome, CHARGE association, diabetic embryopathy, and other rarer conditions. Autoimmune thyroid dysfunctions (Hashimoto's thyroiditis and Graves' Disease) are described in the literature as the most common autoimmune disease after thymic transplant.<p class="...

Introduction: Peripubertal children with delayed puberty frequently display a poor growth rate prompting endocrine work-up. Whether priming with sex steroids should routinely be performed in these patients to improve specificity of growth hormone stimulation tests (GHST) is unclear. Treatment with sex steroids in constitutional delay of growth and puberty (CDGP) is also debated.Patients and Methods: This multicenter retr...

Introduction: Hyperinsulinaemic Hypoglycaemia (HH) is one of the commonest causes of hypoglycaemia in infancy. It is characterised by hypoketotic, hypofattyacidaemic and hyperinsulinaemic hypoglycaemia. The molecular basis of HH includes defects in pathways that regulate insulin release; to date, 12 genes have been associated with monogenic forms of HH (ABCC8, KCNJ11, GLUD1, GCK, HADH1, UCP2, MCT1, HNF4A, HNF1A, HK1, PGM1, PMM2). However, no genetic aetiology has been...

Background: Thymus transplantation is undertaken for conditions associated with severe immunodeficiency. These comprise a number of genetic and syndromic associations including 22q deletion syndrome, CHARGE association, diabetic embryopathy, and other rarer conditions. These conditions may also be associated with hypoparathyroidism and patients are therefore at risk of severe hypocalcaemia. There are no published guidelines for calcium replacement in these patients during the ...

Background: A mutation in EIF2S3 (NM_001415; Xp22.11) was previously associated with microcephaly and developmental delay in a single pedigree. EIF2S3 encodes the eukaryotic translation initiation factor 2 subunit 3 (eIF2γ), the largest of three EIF2 subunits. EIF2 initiates protein synthesis by forming a ternary complex with GTP and initiator methionyl-tRNA which then binds to the 40S ribosomal subunit, enabling scanning of mRNA from the 5′ end to...

Background: SOX2 is an early developmental transcription factor implicated in pituitary development; heterozygous SOX2 mutations have been reported in patients with a severe ocular phenotype and hypogonadotrophic hypogonadism (HH) with/without associated abnormalities. SOX2 physically interacts with β-catenin, a member of the Wnt-signalling pathway, via its carboxyl-terminus and it represses in vitroβ-catenin mediated activation.<p class="abstex...
