Eight RAB32 Ser71Arg heterozygotes were subsequently identified by bioinformatic analysis across four clinicogenomic databases (Figure 1, Figure 2, table 3), of whom four individuals of White, North American, or European descent with parkinsonism were identified via the AMP-PD database (US1, US2, US3, and US4). Here, RAB32 is linked to Parkinsonism.
