Abstract:: BACKGROUND: Leucine-rich repeat kinase 2 (LRRK2) p.L1795F variant was proposed as a genetic risk factor for Parkinson's disease (PD). However, its prevalence, phenotype, and origin remain unknown. OBJECTIVE: The aim was to evaluate the frequency and phenotype of p.L1795F in early-onset PD (EOPD) and familial PD compared to healthy controls (HC) in Central Europe. METHODS: Whole-exome sequencing was used to screen 219 EOPD and familial PD patients of Central Europeans compared to HC. Sanger sequencing assessed segregation. Detailed clinical phenotype was evaluated for all positive carriers. RESULTS: p.L1795F was identified in 1.37% (3/219) and 3.23% of familial cases (3/93), with no carriers among HCs (0/303). Segregation analysis confirmed association with PD. Carriers were traced to the eastern Slovak-Hungarian region. It also appears to be associated with a more aggressive phenotype. CONCLUSION: Our data indicate that p.L1795F contributes to PD in Central Europe. Further exploration in larger cohorts is warranted to establish its contribution to global PD risk.
