The proteins (SNCA, HSPA8, HINT1) are associated with neurodegenerative diseases like Parkinson’s, Alzheimer’s, Huntington's, Prion disorders, and Fronto-temporal dementia (Lin et al., 2020, Matsumura et al., 2013, Shchagina et al., 2020, Sung et al., 2005, Wyttenbach and Arrigo, 2009). This evidence concerns the gene SNCA and Parkinson disease.
