Abstract

We report a child with hypoinsulinemic hypoglycemia and distinctive facies, with a diagnosis of the previously described MORFAN (Mental retardation, pre- and post-natal Overgrowth, Remarkable Face, and Acanthosis Nigricans) syndrome of unknown etiology. Whole-exome sequencing revealed a de novo AKT2 mutation. Although AKT2 has been implicated in four patients with hypoinsulinemic hypoglycemia, our report expands phenotypic spectrum to include MORFAN syndrome characteristics.
