Influenza A induced Thyrotoxic Storm Post Haematopoietic Stem Cell Transplantation

Bhayankaram Nuthana Prathivadi , Murray Philip

Background: Thyroid storm is a rare occurrence of severe thyrotoxicosis, most commonly associated with Grave’s disease and is reported to have a high morbidity and mortality. It is particularly rare in children. Whilst there is a scoring system to diagnose thyroid storm in adults, there is not an equivalent for children. Here, we describe the case of a patient who developed thyroid storm secondary to influenza A infection.Case Report: A 13-year-o...

Transcriptomics and Machine Learning Methods Accurately Predict Diagnosis and Severity of Childhood Growth Hormone Deficiency

Murray Philip , Stevens Adam , Koledova Ekaterina , Chatelain Pierre , Clayton Peter

Background: The diagnosis of Growth Hormone Deficiency (GHD) involves the use of GH stimulation tests that require day case admission, multiple blood sampling and are associated with significant adverse effects.Aim: To assess the utility of gene expression (GE) profiling and candidate SNP analysis for the diagnosis of and classification of GHD.Method: Pre-pubertal treatment-naïve children with GHD (n=98) were enrolled from the...

Genetic Insights from Children with Idiopathic Short Stature in the EPIGROW Study

Perchard Reena , Murray Philip , Payton Anthony , Clayton Peter

Background: EPIGROW was a prospective European epidemio-genetic study in children with idiopathic short stature (ISS).Objectives: To identify (1) differences in frequencies of single nucleotide polymorphisms (SNPs) in growth related genes between ISS children and controls, and (2) associations between growth characteristics, IGF status and SNPs in these genes.Methods: Sequence data from EPIGROW was used to determine the difference ...

In vitro and in vivo Evidence for a Growth Inhibitory Role of the Transcription Factor ZBTB38 Throughout Pre- and Post-Natal Life

Parsons Sam , Stevens Adam , Whatmore Andrew , Murray Philip , Clayton Peter

Background: Single nucleotide polymorphisms (SNPs) within the promotor and 5’UTR of the transcriptional factor, ZBTB38, are associated with adult height and idiopathic short stature although their precise auxological effects have not previously been described. In addition, the molecular mechanisms through which ZBTB38 affects growth have not been fully elucidated but potential downstream mediators are suggested to include MCM10 or IGF2.Objectives: <...

Gene Expression Profiling of Children with GH Deficiency (GHD) Prior to Treatment with Recombinant Human Growth Hormone (r-hGH) is Associated with Growth Response Over Five Years of Therapy

Stevens Adam , Murray Philip , Koledova Ekaterina , Chatelain Pierre , Clayton Peter

Background: The relationship of pre-treatment gene expression (GE) to long-term growth response in GHD is unknown. Prediction of long-term response to r-hGH therapy would allow better decision making about start and maintenance doses and hence cost:benefit.Objective and hypotheses: To assess the relationship of baseline GE to response to r-hGH over 5 years of therapy in GHD children.Method: Pre-pubertal children with GHD (n</em...

Integration of Transcriptomic and Epigenomic Data in Childhood Identifies a Subset of Individuals Born Small for Gestational Age (SGA) with "catch-up" Growth Who Become Pre-Hypertensive in Early Adulthood

Garner Terence , Murray Philip , Sellers Robert , Whatmore Andrew , Clayton Peter , Stevens Adam

Background: Children born SGA are known to develop cardiometabolic conditions in adulthood1. Nothing is known about the relationship of the transcriptome (gene expression) and epigenome (DNA methylation) to birth size and the future development of cardiometabolic disease.Aim: To identify, I) differences and functional links between epigenome age-7years, transcriptome age-9years associated and ...

An Integrated Systems Biology Analysis of the Genome, Epigenome and Transcriptome Identifies a Distinct Pattern of Hypermethylation Associated with Low Childhood Growth

Garner Terence , Sellers Robert , Guo Hui , Whatmore Andrew , Clayton Peter , Stevens Adam , Murray Philip

Background: Current data from genome wide association studies (GWAS) explains 24.6% of the variation in adult height from 3290 single nucleotide polymorphisms (SNPs)1. Data on the genetic control of growth velocity during childhood is more limited and no previous studies have linked childhood growth to changes in the transcriptome (gene expression) or epigenome (DNA methylation). Here we present a systems biology approach to understand mid-child...

The Diagnostic Yield of a Targeted Next Generation Sequencing Panel in Children with Short Stature of Undefined Aetiology

Perchard Reena , Murray Philip G , Highton Georgina L , Whatmore Andrew J , Clayton Peter E

Background: Currently, data on the diagnostic yield of targeted gene panels using next generation sequencing (NGS) in children with short stature of undefined aetiology (SSUA) are limited. EPIGROW ( ID NCT00710307) was a prospective European epidemio-genetic study in which a targeted NGS panel including 69 genes associated with short stature (e.g. primordial growth disorders and skeletal dysplasias) was performed in 263 patients and 263 controls. In these pat...

Central Venous Cathether-Associated Thrombosis in Children with Congenital Hyperinsulinism

Yau Daphne , Salomon-Estebanez Maria , Chinoy Amish , Murray Philip G , Banerjee Indi

Introduction: Congenital hyperinsulinism (CHI) is the most common cause of hypoglycaemia in infancy caused by dysregulated insulin secretion. The management of severe hypoglycaemia often requires the administration of high dextrose-containing fluids through a central venous catheter (CVC). However, CVCs carry the risk of complications including thrombosis. We sought to determine the incidence of CVC-associated thrombosis in patients with CHI and examine associated risk factors...

Oscillations in Gene Expression Profiles Across Childhood Highlight the Relation of Growth and Specific Metabolic Functions in Both Sexes

Stevens Adam , Knight Christopher , De Leonibus Chiara , Dowsey Andrew , Swainston Neil , Murray Philip , Clayton Peter

Background: The phases of human growth are associated with gene expression (GE) changes1, raising the possibility that rhythmic patterns of GE occur throughout childhood.Objective: In this study, we have assessed time-series patterns of GE profiles associated with age to characterise oscillations.Methods: GE analysis was conducted on cells of lymphoid origin from normal individuals through childhood (n=87, 43 ma...
