Mutations in the glucocerebrosidase (GBA) gene have been identified as risk factors for PD, with Lewy bodies being implicated in the pathogenic processes of these mutations (Clark et al., 2009; Neumann et al., 2009; Sidransky et al., 2009; Alcalay et al., 2012; Smith and Schapira, 2022). Here, GBA1 is linked to Parkinson disease.
