Analysis of PRKN Variants and Clinical Features in Polish Patients with Parkinson's Disease.

ABSTRACT: The etiology of Parkinson's disease (PD) is still unclear, but mutations in PRKN have provided some biological insights. The role of PRKN mutations and other genetic variation in determining the clinical features of PD remains unresolved. The aim of the study was to analyze PRKN mutations in PD and controls in the Polish population and to try to correlate between the presence of genetic variants and clinical features. We screened for PRKN mutations in 90 PD patients and 113 controls and evaluated clinical features in these patients. We showed that in the Polish population 4% of PD patients had PRKN mutations (single or with additional polymorphism) while single heterozygous polymorphisms (S167N, E310D, D394N) of PRKN were present in 21% of sporadic PD. Moreover, 5% PD patients had more tha
