ICD-11 definition : Glucose-galactose malabsorption is characterised by diarrhoea and severe neonatal
dehydration. Around 300 cases have been described to date. Moderate glucosuria has
also been reported, but fructose absorption is normal. Glucose-galactose malabsorption
is caused by a mutation in the SLC5A1 gene, encoding the glucose-sodium cotransporter,
SGTL1. The mode of transmission is autosomal recessive. The fatal consequences of
this syndrome can be avoided by following a glucose and galactose restricted diet.;
