It is pertinent to note that genetic mutations in carnitine-acylcarnitine translocase (encoded by SLC25A20), which mediates the transport of acylcarnitines into the mitochondrial matrix, cause severe metabolic disorders, including hypoglycemia, myopathy, and muscle weakness in humans (Fukushima et al., 2013; Iacobazzi et al., 2004). The gene discussed is SLC25A20; the disease is metabolic disease.
