Summary
An adult patient with methylmalonic aciduria due to defective cobalamin synthesis (CblA) responsive to vitamin B12 presented suddenly with severe visual impairment ascribed to optic atrophy followed by a fatal multiorgan failure and lactic acidosis but low methylmalonic acid in plasma and urine. Multiple deficiency of oxidative phosphorylation was found in the patient’s liver. We suggest that patients with B12-sensitive methylmalonic aciduria who have a milder clinical course should be carefully monitored for long-term complications.
