Context: Major advances have been made in the genetics and classification of congenital hyperinsulinism (CHI; OMIM #256450).Objective: To examine the molecular and clinical characteristics of the Finnish patients with persistent and transient CHI.Design: A cross-sectional study with the register data and targeted sequencing of 104 genes affecting glucose metabolism.<p class="ab...

Background: Congenital hyperinsulinism (HI) is a group of insulin secretion disorders with highly heterogeneous genetic aetiologies, which may significantly impact on treatment and follow-up. Genetic diagnosis is unsolved in up to 50% of the individuals, but the benefits of retesting including all the recent genetic discoveries has not been previously assessed.Aim: We examined the effectiveness of rescreening the known H...

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...
