CDH1 and open-angle glaucoma: We found 10 candidate POAG genes that were highly expressed in both the CPE and NPE (AKAP13, C1QBP, CHSY1, COL8A2, CYP1B1, FBN1, IBTK, MFN2, TMCO1, and TMEM248), three genes that were expressed significantly higher in the CPE (CDH1, CDKN2B, and SIX1), and six genes that were expressed significantly higher in the NPE (ATOH7, CYP1B1, FBN1, MYOC, PAX6, and SIX6).
