Introduction: We have reported a syndrome of hypoketotic hypoglycaemia due to the de novo p.Glu17Lys mutation in AKT2, a serine threonine kinase central to insulin signalling. We aimed to evaluate further the physiological and cellular consequences of the p.Glu17Lys mutation.Results: Two previously reported 17-year-old men heterozygous for the AKT2 p.Glu17Lys mutation, each of whom had experienced severe fasting hypoglycaemia in early life, were...

AKT serine-threonine kinases are critical mediators of both growth and metabolic actions of insulin. AKT2 is believed to exert predominantly metabolic effects, while AKT1 has been more strongly implicated in growth. We have recently reported that the de novo AKT2 p.Glu17Lys mutation produces a sporadic syndrome of severe persistent hypoinsulinaemic hypoglycaemia associated with left-sided hemihypertrophy. Glucose requirements in affected patients are far lower than seen in hyp...
