There were eight genes that were upregulated (i.e., AFAP1, COL4A1, CPXM1, ETS1, PRKAG2, PTPN1, SH2B3, and TES), and nine that were downregulated (i.e., ANGPTL2, ANTXR1, HHEX, LTBP2, MAFB, ME3, NR1H3, PCSK5, and PRSS23) in POAG-affected SC cells (Table 2). The gene discussed is COL4A1; the disease is open-angle glaucoma.
