Background: Timing of puberty is associated with height, cardiovascular health and cancer risk, with a significant public health impact. Previous studies estimate that 60–80% of variation in the timing of pubertal onset is genetically determined. Self-limited delayed puberty (DP) often segregates in an autosomal dominant pattern, but the underlying genetic background is unknown.Methods: We performed whole exome sequencing in 52 members of 7 families...

Background: Variable rate intravenous insulin infusion (VRIII) is commonly used in unwell patients with diabetes and complex nutritional needs. However, frequent blood glucose monitoring with infusion rate adjustment gives rise to significant safety concerns and is extremely resource intensive. Fully closed-loop (FCL) systems are promising technological advancements in diabetes management. It comprises of continuous glucose monitoring and a control algorithm t...

Background: Pathogenic IGFI gene mutations causing childhood growth failure are rare. Only 5 autosomal recessive mutations, one IGFI copy number variant and 2 heterozygous frameshift mutations are reported. Heterozygous missense IGFI mutations have not previously been described.Objectives: To identify and functionally characterise a novel missense IGFI variant in a patient with postnat...

Background: Childhood growth is an indicator of health/well-being. Growth monitoring identifies treatable conditions in apparently healthy children and prevents inappropriate referrals. Systematic growth monitoring is not currently a UK priority and growth disorders are frequently diagnosed late.Objective: Develop and test the accuracy of GrowthMonitor, an app which enables families to measure a child’s height at h...

Objectives: Differentiated thyroid cancer (DTC) has shown increasing incidence in children and young people <19 years (CYP), and CYP present with more extensive disease than in adults and are at risk of long-term morbidity. A paucity of randomised controlled trials in the field has led to a lack of consensus on how these children should best be managed. These Children’s Cancer and Leukaemia Group and British Society for Paediatric Endocrinology and Diabetes commission...

Introduction: Patients with type 1 diabetes (T1D) are at high risk of developing vascular complications. Endothelial dysfunction is considered the early reversible stage in the development of diabetes related vascular disease. Early detection and management of endothelial dysfunction can delay or even prevent the development of vascular complications.Aim: Endothelial dysfunction is associated with poor metabolic control in adolescents with T1D. Based on ...

Objective: AMH causes fetal paramesonephric duct regression and is involved in testicular development and function. Sertoli cell AMH remains high during childhood until puberty. The appendix testis (AT), a remnant of the paramesonephric duct, contains both androgen and estrogen receptors. AT androgen receptors have been reported to play a role in embryonic testicular descent. The AT is commonly resected during orchiopexy and abdominal surgery as possible torsion in the future ...

Background: Growth Hormone Insensitivity (GHI) is usually caused by mutations in the Growth Hormone receptor (GHR). Patients present with short stature associated with high GH and low IGF-I levels and often have midfacial hypoplasia (typical Laron syndrome facial features). Our centre previously described the first GHR pseudoexon mutation (42700896A>G, c. 618+792A>G). The inclusion of this 108bp pseudoexon is predicted to lead to in-frame insertion of...

Background: Chronic hemolytic anemias may compromise growth through multiple mechanisms. To date, no data exist on growth and body composition (BC; bone, muscle and fat mass) of children and adolescents with chronic hemolysis.Purpose: To evaluate growth and BC of patients with thalassemia intermedia (not on regular transfusions; thal-intermedia), alpha-thalassemia and congenital spherocytosis....

Background: Survivors of childhood cancer are at increased risk of cardiovascular morbidity and mortality in later life. Although the brain is known to be involved in control of metabolic functions including appetite regulation and energy expenditure (1), little data are available relating to the risk of metabolic dysfunction secondary to cerebral injury. Several studies have attempted to investigate the impact of exercise on physical and psychosocial parameters in survivors o...
