Through a high-throughput screen, we recently identified 38 genes whose knockdown modulates αSyn propagation. Here, we show that, among those, TAX1BP1 regulates how αSyn interacts with lipids, and ADAMTS19 modulates how αSyn phase separates into inclusions, adding to the growing body of evidence implicating those processes in PD. Through RNA sequencing, we identify several genes that are differentially expressed after knockdown of TAX1BP1 or ADAMTS19 and carry an increased frequency of rare risk variants in patients with PD versus healthy controls. Those differentially expressed genes cluster within modules in regions of the brain that develop high degrees of αSyn pathology. We propose a model for the genetic architecture of sporadic PD: increased burden of risk variants across genetic networks dysregulates pathways underlying αSyn homeostasis and leads to pathology and neurodegeneration.
