SLC2A1 and Leigh syndrome: Among these, KD proved beneficial in metabolic epilepsies involving dysfunctional energy utilization (e.g., glucose transporter type 1 deficiency syndrome (GLUT1‐DS) and pyruvate dehydrogenase complex deficiency) or abnormal neurotransmitter degradation (succinic semialdehyde dehydrogenase deficiency and non‐ketotic hyperglycinemia), as well as in mitochondrial epilepsies (e.g., POLG‐related disorders and Leigh syndrome) (Gavrilovici & Rho, 2021; Lin Lin Lee et al., 2018).
