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...

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 ...

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: <...

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...

Introduction: Growth promoting effects of GH occur in parallel with its impact on insulin sensitivity and lipid metabolism; underlying biological networks that link these actions are not defined. Our objective was to identify gene expression (GE) networks linking growth with metabolic responses in GH-treated children with GHD.Methods/design: Pre-pubertal children with GH Deficiency GHD (n=125) were enrolled from the PREDICT short-term (NCT002561...

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 ...

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...

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 (ClinicalTrials.gov 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...

South Asian (SA), British-born adults have increased cardiovascular (CV) risk factors compared to White Europeans (WE). Early detection of CV risk may allow intervention. The Manchester HAPO (Hyperglycaemia and Adverse Pregnancy Outcomes) cohort showed babies of SA origin were born significantly shorter, lighter and had a lower mean BMI SDS than those of WE origin. We now report ethnic differences in body composition and CV markers in childhood. Measurements on 102 children (5...

Background: GRB10 negatively regulates IGF1 signalling, influences growth and promoter polymorphisms are associated with GH response1. GRB10 knockout-mouse models display foetal overgrowth2, however, the mouse model has only partial similarity to human growth3. There is evidence that the zebrafish is an appropriate model to study growth4 and has the advantage of being easily genetically manipulated.<p class="abs...
