Synucleinopathies, including Parkinson’s disease (PD) and dementia with Lewy bodies (DLB), are a heterogeneous group of neurodegenerative disorders neuropathologically defined by the abnormal accumulation of α-synuclein (α-Syn) protein and neuronal cell loss in the nervous system [1, 2]. This evidence concerns the gene SNCA and synucleinopathy.
