Neonatal diabetes with a rare LRBA mutation

BMJ Case Rep. 2022 Nov 24;15(11):e250243. doi: 10.1136/bcr-2022-250243.

Abstract

Neonatal diabetes mellitus (NDM) is characterised by onset of persistent hyperglycaemia within the first 6 months of life. NDM is frequently caused by a mutation in a single gene affecting pancreatic beta cell function. We report an infant, born to a non-consanguineous couple, who presented with osmotic symptoms and diabetic ketoacidosis. The genetic analysis showed a mutation in LRBA (lipopolysaccharide-responsive and beige-like anchor protein) gene. We highlight the importance of considering genetic analysis in every infant with NDM, to understand the nature of genetic mutation, associated comorbidities, response to glibenclamide and future prognosis.
