No significant associations with POAG were identified with SNPs in known glaucoma genes (MYOC, WDR36 and CYP1B1), in regions that have been identified in association studies in other populations (TMCO1, CAV1/CAV2, CDKN2B and SIX1/SIX6) and other candidate genes for heritable ocular quantitative traits associated with POAG (the collagen genes COL1A1, COL1A2 and COL5A1, COL8A2, the region of ZNF469, CDKN2B, SIX1/SIX6 and ATOH7). The gene discussed is COL1A1; the disease is glaucoma.
