Some genes increase the risk of PD, such as α-synuclein (SNCA), parkin (PARK2), PTEN-induced putative kinase 1 (PINK1), oncogene DJ-1 (DJ-1), leucine-rich repeat kinase 2 (LRRK2) and ATPase type 13A2 (ATP13A2) have emerged from previous investigations[2, 3]. The gene discussed is PINK1; the disease is Parkinson disease.
