5-10-methylenetetrahydrofolic-acid and Autism-Spectrum-Disorder

Autism spectrum disorders (ASDs) are neurodevelopmental disorders with an increasing prevalence but lack reliable biomarkers for early diagnosis. The present study investigated 13 serological metabolites and 2 genetic variants related to folate metabolism in a total of 89 ASD cases and 89 matched controls. Fisher discriminant analysis was used to establish the classification model to recognize ASD cases and controls. Ten metabolites were significantly different between the groups, of which six metabolites were used as predictors to determine the discriminant prediction model: vitamin B12, 5-methylene-tetrahydrofolate, methonine, the ratio of S-adenosylmethionine/S-adenosylhomocysteine, methionine synthase and transcobalamin II. The model had statistical significance (lambda=0.520, χ
