The rs1024531 GRB10 Promoter Polymorphism is Associated with Response to GH Therapy in Patients with GH Deficiency: Validation by in vitro Functional Analysis

De Leonibus Chiara , Hanson Daniel , Murray Philip , Stevens Adam , Clayton Peter

Background: GH response is influenced by genetic polymorphisms, including the rs1024531 polymorphism (A/G) in the promoter region of GRB10, a negative regulator of signaling through the IGF1 receptor. Allele A is associated with borderline lower baseline IGF1 SDS and 1.5-fold higher response to GH compared to allele G in children with GHD (P=0.0006).Objective: To test functional impact of the rs1024531 polymorphism in an in vitro</e...

The In vitro Functional Analysis of Gene Promoter Region Single Nucleotide Polymorphisms Associated with GH Response in Children with GH Deficiency

De Leonibus Chiara , Murray Philip , Hanson Dan , Stevens Adam , Clayton Peter

Background: Response to GH treatment has been associated with single nucleotide polymorphisms (SNPs) within the promoter region of growth-related genes including GRB10 (rs1024531 (A/G, allele A increased response)), IGFBP3 (rs3110697 (G/A, G increased response)), CYP19A1 (rs10459592 (T/C, T increased response)) and SOS1 (rs2888586 (G/C, C increased response)). SOS1 is a positive regulator of GH signalling (MAPK pathway); the aromatase CYP19A1 promotes oestrogen synthesis to im...

Bardet-Biedl Syndrome: A retrospective study of progression through puberty

Whitehead Jennifer , Schoeneberg Dillon , Sparks Kathryn , Forsythe Elizabeth , Beales Philip , Peters Catherine , Dastamani Antonia , Katugampola Harshini ,

Introduction: Bardet-Biedl syndrome (BBS) is a rare, pleiotropic, autosomal recessive disorder, with prevalence between 1 in 100,000 – 160,000 in Europe and the USA. It is characterised by 6 cardinal features: rod-cone dystrophy, truncal obesity, cognitive impairment, hypogonadism and genitourinary anomalies, postaxial polydactyly and renal dysfunction, as well as a plethora of secondary features spanning multiple body systems. BBS belongs to a family of ...

Pre-treatment Blood Transcriptome Predicts Growth Response to Somapacitan Treatment in Children Born Small for Gestational Age

Garner Terence , Clayton Peter , Højby Rasmussen Michael , Murray Philip , Stevens Adam

Treating short stature in children born small for gestational age (SGA) requires daily growth hormone (GH) injections that are burdensome for patients and caregivers. Results from REAL5 (ongoing randomised, multinational, open-label, controlled, dose-finding phase 2 trial; NCT03878446) indicate that somapacitan (0.24 mg/kg/week) has an efficacy, safety, and tolerability profile similar to daily GH (0.067 mg/kg/day) after 52 weeks of treatment in children born SGA. Predicting G...

Response to Daily and Weekly Recombinant Human Growth Hormone Treatment in Children Born Small for Gestational Age is Predicted More Accurately by Pre-treatment Blood Transcriptome than Clinical Variables

Garner Terence , Murray Philip , Højby Michael , Ard Ryan , Clayton Peter , Stevens Adam

Background: &grave;(LAGHs) are under investigation to treat SGA. Results from the REAL5 phase 2 trial (randomised, multinational, open-label; NCT03878446) indicate that the LAGH somapacitan has similar efficacy, safety, and tolerability profile as daily GH1. Predicting GH therapy response is critical to improve clinical management of short stature. Here, we compare the prediction of growth response in SGA children treated with daily GH or somapacitan based on ...

Estrogen and progesterone in immune dysfunction at childhood follow up of preterm infants

Stewart Philip , Byrne Dearbhla , Branagan Aoife , Isaza-Correa Johana , Kelly Lynne , Meehan Judith , Molloy Eleanor

Background and Aims: Infants born prematurely have increased risk of multi-organ dysfunction and death throughout their lives. Males are particularly higher risk and susceptible to the adverse effects of infection related inflammation with poorer clinical outcomes. Immune function, hormone exposure and genetic factors play contributory roles. Physiological concentrations of female hormones hypothesised to have a role in immune development, could affect the exp...

Feasibility of integrating an mHealth intervention to increase exercise and physical activity adherence into a weight management service for adolescents with severe obesity: MOTIVATE-WMA

Davies Andrew , Hesketh Katie , Clarke Ellie , Apperley Louise , Sprung Victoria , Jones Helen , Senniappan Senthil , Cocks Matthew

Introduction: The Royal College of Paediatrics and Child Health state that adolescents with significant obesity require access to evidence-based weight management services (WMS). Due to the known benefits of exercise and physical activity (PA) on physiological and psychological outcomes increasing exercise and PA should form a cornerstone of any WMS for adolescents living with obesity. However, supervised exercise interventions face challenges within a clinica...

Refractory Hyperinsulinaemic Hypoglycaemia in Beckwith-Wiedemann Syndrome due to Imprinting Centre 1 Gain of Methylation: Severity Discordant to Genotype

Conwell Louise , McBride Craig , Choo Kelvin , Tadgell Shawn , Fuery Michelle , Davies Janene

Introduction: Beckwith-Wiedemann syndrome (BWS) is an overgrowth syndrome caused by multiple epigenetic/genetic changes affecting imprinted genes in 11p15.5 region. Phenotypic expression is variable. Hyperinsulinaemic hypoglycaemia is common (30-60%). Persistent, severe, refractory cases are usually associated with 11p15 paternal uniparental disomy, particularly the rare context of a coexisting paternal inactivating KATP channel variant. Those c...

Dysautonomia and Acyl Ghrelin in Prader–Willi syndrome

Nyunt Ohn , Archbold Sinead , Donelly Jennifer , Jeffery Penelope , Cotterill Andrew , Davies Peter , Harris Mark

Background: Poor temperature regulation in Prader–Willi syndrome (PWS) suggests dysautonomia probably secondary to hypothalamic dysfunction. Autonomic nervous system (ANS) has control over orexigenic ghrelin.Objective and hypotheses: We aim to assess ANS function in PWS and its association with acyl ghrelin.Method: We recruited 16 genetically-confirmed children with PWS and 16 controls. Exclusion criteria were diabetes mellitu...

Heterozygous PLAG1 gene variants causing Silver-Russell syndrome in a case series of 4 patients

Juriaans Alicia , Lachlan Katherine , Carmichael Jenny , Davies Justin , Mackay Deborah , Temple Karen , Gazdagh Gabriella

Background: Silver-Russell syndrome (SRS) is a clinically and genetically heterogeneous syndrome, characterized by pre- and postnatal growth restriction among other features. Pathogenic variants in genes involved in the HMGA2-PLAG1-IGF2 pathway have been found to cause an SRS phenotype. Here we present four individuals with variants in the PLAG1 gene, exhibiting features of SRS. Two siblings of the same family inherited the PLAG1 variant from...
