Fanconi-Bickel syndrome (FBS) is a rare autosomal recessive carbohydrate metabolism disorder caused by mutations in SLC2A2 encoding the glucose transporter 2 (GLUT2) protein. The clinical manifestations include hepatomegaly, conditional hypo/hyperglycemia, rickets, short stature and proximal renal tubular dysfunction. GLUT2 regulates monosaccharide homeostasis through sugar sensing and transmembrane transportation during high/low glucose levels. In the current study, we present two siblings suffering from FBS. The patients presented with doll-like facies, failure to gain weight and height, abdominal distension and firm hepatomegaly. The family had a history of deaths of twin male siblings in the neonatal period and twin female siblings at ages 10 months and 2.5 years, respectively. Clinical presentation and biochemical investigations including a complete blood count, electrolytes, liver and renal function tests suggested FBS. Mutation screening of SLC2A2 confirmed the diagnosis with identification of a novel homozygous splice site variant predicting an in-frame deletion [p.(Gly166-S169del)] in the GLUT2 protein. The in-silico analysis predicted the variant to affect the three-dimensional conformation of the fourth transmembrane helix of the encoded protein, rendering the non-functionality of GLUT2 in both patients of the family under study.
