LRRK2 and Parkinson disease: In addition to PARK6 (encoding PINK1) and PARK2 (encoding Parkin), other genes associated with Parkinson’s disease, such as PARK7 (encoding the DJ-1 protein) and PARK8 (encoding the LRRK2 protein), are also thought to be mutated in patients with Parkinson’s disease (Walter et al., 2019).
