Concentrations of PCho, a choline storage form and intermediate in the cytidine-diphosphocholine (CDP) choline pathway for PtdCho synthesis, were also significantly lower due to the Mthfr +/− genotype, as were the concentrations of PtdCho and its catabolite SM, with borderline significance for another catabolite, LysoPtdCho ( P = 0.057).
