Plasma C14:1 and C14:2 were elevated in VLCAD deficiency, C14OH, C16OH and C18:1OH levels in LCHAD/MTP deficiencies, C6 and C8 in MCAD deficiency, C2 and C4 in SCAD deficiency, and C0/(C16 + C18) in CPT1A deficiency. This evidence concerns the gene CPT1A and short chain acyl-CoA dehydrogenase deficiency.
