Nature and nurture in vitamin B12 deficiency.

Archives of disease in childhood - 1 Jul 2002

Zschocke J, Schindler S, Hoffmann G F, Albani M

Abstract excerpt

We report on a child in whom severe nutritional vitamin B12 deficiency was exacerbated by a genetic impairment of the folate cycle, causing reduced CSF concentrations of the methyl group donor 5-methyltetrahydrofolate. Some patients with vitamin B12 deficiency may benefit from high dose folic acid supplementation, even if plasma concentrations are high.
