This protective effect was observed in these PD subgroups under the dominant mode of inheritance as well (GBA1-PD: dominant OR = 0.700, CI = 0.530–0.923, p = 0.012; LRRK2-PD: dominant OR = 0.678, CI = 0.478–0.961, p = 0.029; and NC-PD: dominant OR = 0.771, CI = 0.655–0.909, p = 0.002). Here, LRRK2 is linked to Parkinson disease.
