Neonatal diabetes mellitus with hypergalactosemia

We report the case of a male, small-for-gestational-age newborn who present ed with failure to thrive, severe fluctuation of blood glucose concentratio ns, and increased serum concentrations of galactose. The infant responded w ell to a lactose-free diet supplemented with fructose, inulin and corn star ch. The metabolic disorder disappeared within 6 months. The transient cours e, and results of a molecular analysis of the glucose transporter 2 (Glut2) gene seem to rule out Fanconi-Bickel syndrome.
