A Novel Missense Variant in the Insulin Receptor Gene in Three Unrelated Irish Families with Severe Insulin Resistance Syndrome: Evidence for an Irish Founder Effect

Mavinkurve M , O'Connell S , Cody D , Isaac I , Harris J , Semple R K , Mc Donnell C

Background: Genetic defects in the insulin receptor (INSR) are rare. Precise prevalence is unknown and significant clinical heterogeneity exists. Over 120 allelic variants have been described to date, spread throughout the receptor, and few geographical founder effects have been described. In this case series we identify a novel missense mutation in the tyrosine kinase domain of the INSR in three independently ascertained Irish families.Objective and Hyp...

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...

Monogenic Diabetes in a Paediatric Population: Finding the Needle in the Haystack

Mavinkurve M , Johnston N , Carroll A , Donnell C Mc , Byrne M M , Murphy N P

Background: Ireland has a high incidence of type 1 diabetes in childhood (16.8/100, 000 per year (1). A small percentage of children with diabetes have maturity onset diabetes of the young (MODY) (2). Establishing the correct diagnosis is critical to optimal therapy and future genetic counselling (3).Objective and hypothesis: To review the cohort of children attending our tertiary diabetes service and describe the clinical features of those where MODY wa...
