High Concentration Methylcobalamin (Me-Cbl) or Combination of Methyl- and Hydroxocobalamin (Me/OH-Cbl) for the Treatment of Cobalamin C Deficiency and Related Disorders

Cobalamin C deficiency (cblC), caused by mutations in MMACHC, is the most common inborn error of intracellular vitamin B12 metabolism. NHGRI scientist have generated a number of Mmachc knockout mouse models. The cblC mice present with early lethality, recapitulate the neurological phenotype seen in patients, and have enabled proof of concept testing...

Aberrant Post-translational Modifications (PTMs) in Methyl- and Propionic Acidemia and the Construction of a Novel Sirtuin (SIRT) Gene to Metabolize PTMs

Isolated Methylmalonic Acidemia (MMA) and the related disorder Propionic Acidemia (PA) comprise a relatively common and heterogeneous group of inborn errors of metabolism. NHGRI scientist discovered that in isolated MMA, a novel inhibitory PTM, methylmalonyllysine, is generated and inactivates protein targets through the failure of SIRT-mediated deacylation,...
