Abstract Background: Parkinson’s disease (PD) is caused by the interplay of genetic and environmental factors during brain aging. About 90 single nucleotide polymorphisms (SNPs) have been recently discovered associating with PD, but their associations with PD clinical features have not been fully characterized yet. Methods: Clinical data of 377 patients with PD who enrolled in Parkinson's Progression Markers Initiative (PPMI) study were obtained. Patients with rapid cognitive or motor progression were determined through clinical assessments over five years follow-up. In addition, genetic information of 50 targeted SNPs was extracted from the genetic database of NeuroX for the same cohort. Genetic associations with rapid motor and cognitive dysfunction of PD were analyzed using SPSS-logistic regression. Results: Among 377 patients with PD, there are more male (31%) than female (17%) prone to have rapid motor progression (pppConclusions: Genetic factors contribute to the disease progression as well as the clinical features at the disease onset.
