LRRK2 and Parkinson disease: To further examine the genetic variations of LRRK2 in Taiwanese PD, we sequenced the LRRK2 coding region in 70 Taiwanese PD patients and assessed the association of identified SNPs with the risk of PD by utilizing a large case-control cohort of patients and controls, to provide more insight into LRRK2 variants in Taiwanese PD patients.
