The modifying effect of mutant LRRK2 on mutant GBA1-associated Parkinson disease.

ABSTRACT: Parkinson disease (PD) is the second most common neurodegenerative disease. While most cases are sporadic, in ~ 5%-10% of PD patients the disease is caused by mutations in several genes, among them GBA1 (glucocerebrosidase beta 1) and LRRK2 (leucine-rich repeat kinase 2), both prevalent among the Ashkenazi Jewish population. LRRK2-associated PD tends to be milder than GBA1-associated PD. Several recent clinical studies have suggested that carriers of both GBA1 and LRRK2 mutations develop milder PD compared to that observed among GBA1 carriers. These findings strongly suggested an interplay between the two genes in the development and progression of PD. In the present study Drosophila was employed as a model to investigate the impact of mutations in the LRRK2 gene on mutant GBA1-associated
