Some disorders of intracellular cobalamin metabolism (cblC, cblD-MMA/Hcy, cblF, and cblJ) do not only compromise the synthesis of methylcobalamin, but also the synthesis of adenosylcobalamin, cofactor of the enzyme methylmalonyl-CoA mutase, leading to elevated concentrations of both tHcy and methylmalonic acid (MMA)
