Introduction: Hyperinsulinaemic Hypoglycaemia (HH) is one of the commonest causes of hypoglycaemia in infancy. It is characterised by hypoketotic, hypofattyacidaemic and hyperinsulinaemic hypoglycaemia. The molecular basis of HH includes defects in pathways that regulate insulin release; to date, 12 genes have been associated with monogenic forms of HH (ABCC8, KCNJ11, GLUD1, GCK, HADH1, UCP2, MCT1, HNF4A, HNF1A, HK1, PGM1, PMM2). However, no genetic aetiology has been...
