Takeaway
Ashkenazi Jewish (AJ) patients carrying glucocerebrosidase (GBA) variants are more susceptible to Parkinson’s disease (PD) with higher prevalence of non-motor features compared to patients carrying a single mutation of leucine-rich repeat kinase 2 (LRRK2) or both.
Why this matters
Clinical genetic analysis of GBA and LRRK2 variants could help determine the genetic susceptibility to PD in the AJ population.
