Copyright © 2020 Wang, Li, Sun, Yang, Yang, Liu, Liu, Hu and Zhang. Cellular respiration (oxidative phosphorylation) occurs in the mitochondria, where a series of enzymes catalyze the transfer of electrons to molecular oxygen and the generation of energy-storing adenosine triphosphate (ATP). Furthermore, the suppressive effect of α-KG on ATP synthase plays an important role in the low levels of oxidative phosphorylation in SMMC-7721 cells; this effect could be strengthened by the metabolic poison methotrexate and reversed by L-(-)-malic acid, an accelerator of the malate-aspartate cycle. Their parents were heterozygous mutation carriers without clinical manifestations. COXPD8 is an autosomal recessive disorder due to dysfunction of the mitochondrial respiratory chain. Birth weight, length, and head circumference were within normal limits. Table 1 summarizes the clinical characteristics and the laboratory test results of the two brothers.
