Introduction. Genetic forms of Parkinson's disease (PD) often cluster in different ethnic groups and may present with recognisable unique clinical manifestations. Our aim was to summarise the current state of knowledge regarding the genetic causes of PD and describe the first Polish patient with SNCA duplication. Methodology. We searched the electronic database, PubMed, for studies between January 1995 and June 2020 that evaluated genetics in Polish patients with PD, using the search terms 'Parkinson's disease, 'Polish', 'genetics', 'mutations', and 'variants'. Results. In total, 73 publications were included in the review; 11 genes responsible for monogenic forms and 19 risk factor genes have been analysed in the Polish population. Pathogenic variants were reported in four monogenic genes (LRRK2, PRKN, PINK1, and SNCA). Eight genes were associated with PD risk in the Polish population (GBA, TFAM, NFE2L2, MMP12, HLA-DRA, COMT, MAOB, and DBH). Multiplex ligation-dependent probe amplification and Sanger sequencing in PRKN, PINK1, DJ1, LRRK2, and SNCA revealed SNCA duplication in a 43-year-old Polish patient with PD examined by movement disorder specialists. Conclusion. Only a limited number of positive results have been reported in genes previously associated with PD in the Polish population. In the era of personalised medicine, it is important to report on genetic findings in specific populations.
