    The study developed VARI3, a genome-wide epistasis screening pipeline, to identify interactions linked to Parkinson's disease.

  • 2

    Using 14 cohorts of European ancestry, 14 significant candidate variant–variant interactions were identified in the discovery stage.

  • 3

    Three epistatic signals near SNCA and within MAPT and WNT3 were successfully replicated in four independent cohorts.

  • 4

    Admixture analysis revealed that the epistatic effects were present in individuals of both European and Native American ancestry.

  • 5

    The identified epistatic signals were enriched in pathways relevant to Parkinson's disease, highlighting their functional significance.
