While the exact role of SV2C in dopaminergic neurotransmission and PD pathology remains to be fully elucidated, this study is pivotal in establishing the potential significance of SV2C in dopaminergic neurons and serves as a crucial foundation for future investigations aimed at unraveling the functions of SV2C and its implication for PD. The gene discussed is SV2C; the disease is Parkinson disease.
