    Abstract:
    Fanconi-Bickel syndrome is a rare autosomal-recessive disorder caused by mutations in the SLC2A2 gene coding for the glucose transporter protein 2 (GLUT2). Major manifestations include hepatomegaly, glucose intolerance, post-prandial hypoglycaemia and renal disease that usually presents as proximal tubular acidosis associated with proximal tubule dysfunction (renal Fanconi syndrome). We report a patient harbouring a homozygous mutation of SLC2A2 who presented a dramatic exacerbation of metabolic acidosis in the context of a viral infection, owing to both ketosis and major urinary bicarbonate loss. The kidney biopsy revealed nuclear and cytoplasmic accumulation of glycogen in proximal tubule cells, a lack of expression of GLUT2, and major defects of key proteins of the proximal tubule such as megalin, cubilin and the B2 subunit of H(+)-ATPase. These profound alterations of the transport systems most likely contributed to proximal tubule alterations and profound bicarbonate loss.
