Abstract [en]

Definition, structure and biochemical background Similar to other “proteinopathies,” the process that links α-synuclein (αS) protein to disease pathogenesis originated from the discovery that a single point mutation in the αS gene (i.e. SNCA) can cause autosomal-dominant Parkinson’s disease (PD) [1]. This was followed by the breakthrough finding that the actual transcribed protein was a major fibrillar component of pathological hallmarks known as Lewy bodies (LBs), Lewy neurites (LNs) and glial cytoplasmic inclusions characterizing a heterogeneous group of diseases, now collectively referred to as “synucleinopathies,” i.e. PD, PD with dementia (PDD), dementia with Lewy bodies (DLB) and multiple system atrophy (MSA) [2, 3]. Currently, there are five missense mutations (pA53T, p.A30P, p.E46K, p.H50Q and p.G51D) [1, 4–8] and multiplication mutations (SNCA duplication and triplication) [9–11] that are genetically linked to clinical parkinsonism (Table 9.1). This genetic and pathological linkage establishes αS as an important player in the development of these disorders.
