Results for the combinations of metabolites from all subsets (i-iv) with lowest errors

Subset	Combination	Type I Error	Type II Error
(i): FOCM/TS Metabolites	tCysteine, Glu-Cys, fCysteine, fCystine/fCystiene, Nitrotyrosine	24%	27%
(ii): FOCM/TS metabolites plus nutritional information	SAM/SAH, Glu-Cys, GSSG, fCysteine, B12	24%	27%
(iii): FOCM/TS metabolites, nutritional information, and MTHFR gene information	SAM/SAH, tCysteine, Glu-Cys, B12, MTHFR mut. (A1298C)	24%	20%
(iv): FOCM/TS metabolites, nutritional information, MTHFR gene information, and Metabolon metabolites	Glu-Cys, histidylglutamate, cinnamoylglycine, proline, adrenoylcarnitine (C22:4)a	3%	3%

The ^a indicates metabolites measured by Metabolon that were not officially confirmed based on a standard, but Metabolon is confident of the Metabolite’s identity
