    ..These findings shed further insights into the mechanisms by which genetic and dietary folate metabolic disturbances increase the risk for cognitive decline and suggest that these mechanisms are distinct. ..

    ..Increases in the inflammatory marker CRP (logistic regression, p = 0.055) and BMI (chi-square, p = 0.0113) were associated with AA genotype in women with low folate. MTHFD1 1958G>A may influence immune function and obesity. ..

    ..We suggest that deficiencies in maternal one-carbon metabolism during pregnancy can contribute to hippocampal dysfunction in offspring through apoptosis or altered choline metabolism. ..

    ..These findings have implications for women with high folate intakes, particularly if they are polymorphic for MTHFD1 R653Q. ..
