Background: We previously reported the first human mutation in mini-chromosome maintenance homologue 4 (MCM4) in a cohort of patients with adrenal failure, immunodeficiency and chromosomal fragility.Objective and Hypotheses: To report the full endocrine phenotype of 14 patients with MCM4 mutations.Method: Patients case notes were examined and investigations performed to fully assess adrenal function, pubertal development, gonadal f...

Background: Ireland has the highest prevalence of Down syndrome (DS) in Europe, affecting ~1 in 500 live births. Patients with DS are at increased risk of developing thyroid disorders during childhood. Hyperthyroidism can be difficult to recognise and treat in this population. First-line therapy with anti-thyroid drugs (ATDs) may help achieve remission, but relapse is common following discontinuation of medication. Definitive treatment with radio ablation or surgery is often c...

Background: Neonatal thyrotoxicosis, a rare and life-threatening condition, is caused by transplacental transfer of thyroid stimulating immunoglobulins from mother to infant. While clinical features may include goitre, prominent eyes and poor weight gain, these may be absent in some cases. Early diagnosis and treatment of affected infants is critical.Objective: We report a case series of infants with neonatal thyrotoxicosis from two tertiary paediatric h...

Background: Cystic fibrosis-related diabetes (CFRD) is a common complication in cystic fibrosis (CF). CFRD symptoms and treatment may impose additional burden and adversely affect their QoL.Objective and hypotheses: Assess HRQoL in CF children with normal glycaemia (CFN) and CFRD and evaluate the change in HRQoL over 1 year period along with clinical changes.Method: A prospective study was undertaken including children aged 10&#150...

Background: In 2007, non-coding variants in the promoter of SLC16A1, a beta-cell disallowed gene, were reported as a novel genetic cause of exercise-induced hyperinsulinism (HI). In this study, three different promoter variants were identified in 13 affected individuals from three families. It was proposed that these variants caused MCT1, which is encoded by SLC16A1, to be inappropriately expressed in the pancreatic beta cells resulting in insulin secretion in...
