Interestingly, SOD1 showed interaction with OPTN involved in neuroinflammation, autophagy, and vesicular trafficking in ALS (Maruyama et al., 2010), FTD (Hortobagyi et al., 2011), Alzheimer’s disease, and Huntington’s disease (Schwab et al., 2012). The gene discussed is OPTN; the disease is juvenile Huntington disease.
