There are many known and hypothesized genes linked with PD, as outlined on the slide.2-5 Indeed, some have argued that PD can be viewed as predominantly a genetic disease, in which all the known environmental factors act within the context of genetic risk.3 This does not ignore the known environmental factors influencing PD risk – and indeed the increase in the prevalence of PD seen in the past decades – but rather argues that these factors are interacting with underlying genetics to produce disease.3
