Revisiting the non-Gaucher-GBA-E326K carrier state: Is it sufficient to increase Parkinson's disease risk?

ConclusionsCompared to previous studies, we demonstrate here a higher frequency of PD patients that carry two mutations. The GBA-E326K is more likely to affect PD risk when accompanied by another mutation, and an additive effect on risk and earlier AAO was proposed for carriers of LRRK2/mild-GBA double mutations. Altogether, these data support an oligogenic approach to PD genetics.
