Parkinson’s disease (PD) and multiple system atrophy (MSA) are neurodegenerative illnesses defined by an abnormal accumulation of alpha-synuclein aggregates in neurons, nerve fibers, and glial cells (Srinivasan et al., 2021; Reddy and Dieriks, 2022; Woerman et al., 2018). Here, SNCA is linked to multiple system atrophy.
