PARK7 and Parkinson disease: Among the six genes associated with heritable, monogenic PD, mutations in the genes SNCA (PARK1) and LRRK2 (PARK8) are linked to autosomal-dominant forms, while mutations in Parkin (PARK2), PINK1 (PARK6), DJ-1 (PARK7), and ATP13A2 (PARK9) are associated with autosomal recessive inheritance [71].
