Objective: Variations in PARK genes (PRKN, PINK1, DJ-1, and SNCA) cause early-onset Parkinson's disease (EOPD) in different populations. In the current study, we aimed to evaluate the frequencies of variations in PARK genes and the effects of these variations on the phenotypes of Turkish EOPD patients.
