The genes significantly impacted by infection only in CS included mast cell proteinase-3, γ-glutamyltransferase 5 (GGT5), CD163 as well as those involved in smooth muscle contraction, such as tropomyosin (TPM2), myosin, light chain 9, regulatory (MYL9), and calponin 1, basic, smooth muscle (CNN1). The gene discussed is MYL9; the disease is infection.
