Several genes, such as α-synuclein, parkin, PINK1 (phosphatase and tensin homologue-induced kinase 1), DJ1 (also known as Parkinson disease protein 7, PARK7 gene); and also environmental factors, like physical trauma, infections, and toxic effects have been identified to have a role in PD [4,5]. The gene discussed is PARK7; the disease is infection.
