AI Summary

The study reports an absence of cerebrospinal fluid α-synuclein seeding activity in Parkinson's disease patients harboring VPS35 D620N or LRRK2 Y1699C mutations.

Why It Matters

Indicates pathological and biomarker heterogeneity in genetic PD—α-synuclein seeding assays may not detect disease in these subgroups, impacting patient stratification and the design of α-synuclein-targeted therapies and trials.
