For instance, mutations in PD-associated genes, such as PRKN (PARK2; MIM number 600116), PINK1 (PARK5; MIM number 605909), and DJ-1 (PARK7; MIM number 602533), have often been associated to autosomal-recessive forms of EOPD (Lücking et al., 2000; Bonifati et al., 2005; Olgiati et al., 2016). This evidence concerns the gene PARK7 and Parkinson disease.
