Due to its polar nature, carnitine cannot diffuse freely across cell membranes and depends on specific transporters, principally OCTN2 (SLC22A5)a high-affinity (Km 46 mol/L), sodium-dependent transporter highly expressed in the brush border membrane of the renal proximal tubules [73, 74]

L-2-Hydroxyglutaric aciduria (L-2-HGA) is caused by mutations in the gene encoding L-2-hydroxyglutarate dehydrogenase (LHGDH), leading to the accumulation of L-2-HG in the brain and biological fluids, which is the biochemical hallmark of L-2-HGA [111, 112]
