Glaucoma Association of Genetic Variants in the TMCO 1 Gene with Clinical Parameters Related to Glaucoma and Characterization of the Protein in the Eye

PURPOSE. Glaucoma is the leading cause of irreversible blindness worldwide. Primary open angle glaucoma (POAG) is the most common subtype. We recently reported association of genetic variants at chromosomal loci, 1q24 and 9p21, with POAG. In this study, we determined association of the most significantly associated single nucleotide polymorphism (SNP) rs4656461, at 1q24 near the TMCO1 gene, with the clinical parameters related to glaucoma risk and diagnosis, and determined ocular expression and subcellular localization of the human TMCO1 protein to understand the mechanism of its involvement in POAG.
