We then genotyped for three common pathogenic mutations (p.R1441C/G/H, p.I2012T, and p.G2019S) and the Asian-specific risk polymorphism (p.G2385R) in LRRK2. Among 51 PD patients, three patients carried the LRRK2 mutations (one with LRRK2 p.R1441H mutation and the remaining two with LRRK2 p.I2012T mutations) and 9 had the PD risk p.G2385R polymorphism. Here, LRRK2 is linked to Parkinson disease.
