SOAT1 and Parkinson disease: Pathway enrichment analysis of PD subtypes revealed that 20 pathways, including Lewis X antigen biosynthesis and IL12/23 to JAK-STAT signaling, were activated in Type 2, while 12 pathways, such as Wnt signaling modulation (both Wnt inhibitor and Wnt acylation), were activated in Type 1 (Fig. 7C).
