ABCD3 and peroxisomal disease: Recently discovered new peroxisomal disorders such as deficiencies of ABCD3 (PMP70) (Ferdinandusse et al. 2015), ACBD5 (Yagita et al. 2017; Ferdinandusse et al. 2017; Darwisch et al. 2020) (see “Mysterious shapers, movers, and regulators of peroxisome dynamics”), and ACOX3 (Kim et al. 2020) were also addressed elsewhere (Wanders 2018; Carmichael et al. 2022; Wanders et al. 2023) (Fig. 1).
