Other genes with high expression in MS patient samples were proinflammatory, such as immunoglobulin lambda-like polypeptide 5 (IGLL5), collagen type VIII alpha 1 chain (COL8A1), signaling lymphocytic activation molecule family member 7 (SLAM7), paralemmin 3 (PALM3), and hepatocyte growth factor (HGF). Here, PALM3 is linked to myeloid sarcoma.
