A Novel Mutation in the GLUT2 Gene Case Report of Fanconi-Bickel Syndrome in a Female Indian Patient

Abstract
A female infant born out of 3rd degree consanguineous parents presented at 1 year of age with polyuria, polydipsia and glycosuria for 6 months. History revealed motor developmental delay. Investigations showed fasting hypoglycemia, postprandial hyperglycemia, renal glycosuria, generalized aminoaciduria, and renal rickets. Genetic evaluation revealed a novel mutation in exon2 of SLC2A2 a T-to-G substitution (c56T>G) confirming the diagnosis of Fanconi Bickel syndrome (FBS).
