Another neuropathological feature of PD is the presence of Lewy bodies (LBs) and Lewy neurites (LNs), which are formed by abnormal deposition of α-synuclein (α-syn), dysmorphic organelles, vesicular structures, and lipids in the cytoplasm of neurons in several different brain regions [3, 4]. The gene discussed is SNCA; the disease is Parkinson disease.
