Glucose-Galactose Malabsorption

Glucose-Galactose Malabsorption is an autosomal recessive disorder characterized by reduced intestinal resoption of glucose and galactose. The accompanying renal symptom is glucosuria.

Symptoms

Diarrhea
Diarrhea manifests within the first weeks of life and causes severe life threatening dehydration unless glucose and galactose are eliminated from the diet.
Nephrocalcinosis
In patient with glucose-galactose malabsorption also nephrocalcinosis can develop associated with proximal tubular damage such as acidosis.
Acidosis
Patients with glucose-galactose malabsorption may also show renal tubular acidosis based on proximal tubular damage.

Systematic

Monosacchariduria
Fructosuria
Glucose-Galactose Malabsorption
SLC5A1
Renal Glucosuria
