Phosphomannose isomerase deficiency
WebPhosphomannose-isomerase (PMI) deficiency is a (cytosolic) defect in the first step of the biosynthesis of the nucleotide sugar GDP-Man. The substrate of the enzyme, fructose 6-phosphate, does not accumulate since it is an intermediate of the glycolytic pathway. The blood biochemical abnormalities are indistinguishable from those found in PMM2-CDG.
