Uncontrolled mitochondrial fragmentation might contribute to the development of Parkinson’s disease (Varkey et al., 2010; Panchal and Tiwari, 2019) and, importantly, duplication and triplication of SNCA (α-synuclein) gene cause a severe form of this disease (Olgiati et al., 2015; Konno et al., 2016). Here, SNCA is linked to Parkinson disease.
