Résumé de la thèse

Genetic defects in vitamin B12 or cobalamin (cbl) metabolism lead to a decrease in methionine synthase activity associated with changes in genes expression such as decreased expression of SIRT1. Patients with inherited defects affecting methionine synthase activity present mainly with hematological but also neurological symptoms that persist despite conventional treatment and correction of biochemical parameters.

Abstract

Genetic defects in vitamin B12 or cobalamin (cbl) metabolism lead to a decrease in methionine synthase activity associated with changes in genes expression such as decreased expression of SIRT1. Patients with inherited defects affecting methionine synthase activity present mainly with hematological but also neurological symptoms that persist despite conventional treatment and correction of biochemical parameters.
