Background: Oral LUM-201 normalizes growth rates in moderate PGHD over 12 months (Phase 2 Trials: OraGrowtH210/OraGrowtH212) [FC-746 ESPE 2024]. In OraGrowtH212, GH profiles, based on 10-minute sampling over 12 hours (8am-8pm), showed significant increases in inter-pulse, pulsatile and total GH secretion in response to 1.6 and 3.2 mg/kg/day doses of LUM-201 over 6 months, with no difference between the doses [FC14.3, ESPE 2023].O...

Background: Oxidative stress has been implicated in the development and progression of complications in type 1 diabetes (T1DM). Vitamin E (α-tocopherol) undergoes β-oxidation of its chomanol ring and the resulting metabolite α-TLHQ has been proposed as a potential biomarker of oxidative stress. HbA1c relates in T1DM to microvascular complications predominantly although the end-points are late in disease development. The oxidative stress process may act independe...

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: Many children with short stature (defined as height SDS <−2S.D.) have no identified cause for their growth impairment and are classified as either small for gestational age or idiopathic short stature depending on birth size. Whole exome sequencing (WES) is a useful tool to identify new genetic diagnoses in this group. Here we describe a recurrent NDUFB3 mutation in children with intra-uterine growth retardation, short stature and ...

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...
