Abstract
Objectives: To determine whether alpha-synuclein dinucleotide repeat (REP1) genotypes are associated with survival in Parkinson's disease (PD). Methods: Investigators from the Genetic Epidemiology of Parkinson's Disease Consortium provided REP1 genotypes and baseline and follow-up clinical data for cases. The primary outcome was time to death. Cox proportional hazards regression models were used to assess the association of REP1 genotypes with survival. Results: Twenty-one sites contributed data for 6,154 cases. There was no significant association between alpha-synuclein REP1 genotypes and survival in PD. However, there was a significant association between REP1 genotypes and age at onset of PD (hazard ratio: 1.06; 95% confidence... (More)

Results: Twenty-one sites contributed data for 6,154 cases. There was no significant association between alpha-synuclein REP1 genotypes and survival in PD. However, there was a significant association between REP1 genotypes and age at onset of PD (hazard ratio: 1.06; 95% confidence interval: 1.01-1.10; P value = 0.01). Conclusions: In our large consortium study, alpha-synuclein REP1 genotypes were not associated with survival in PD. Further studies of alpha-synuclein's role in disease progression and long-term outcomes are needed. (C) 2014 International Parkinson and Movement Disorder Society (Less)
