Key result
SNCA gene duplication facilitates the formation of Lewy bodies in the central and peripheral nervous systems, showing the same biochemical profiles as sporadic Lewy body disease.
Why the study?
Multiplication of the alpha-synuclein gene can cause familial Parkinson's disease, but the detailed neuropathological and biochemical profiles across both the central and peripheral nervous systems warranted investigation.
Population
One autopsy case of a patient with SNCA duplication

Case Report (n=1)
SNCA duplication facilitates the formation of Lewy bodies in both the central and peripheral nervous systems, with biochemical profiles identical to sporadic Lewy body disease.
Beck et al. (2025) conducted a case report in Parkinson's disease (SNCA duplication) (n=1). SNCA duplication was evaluated on Neuropathological and biochemical profiles of Lewy pathology. SNCA gene duplication facilitates the formation of Lewy bodies in the central and peripheral nervous systems, showing the same biochemical profiles as sporadic Lewy body disease.
