AbstractPrevious studies have reported the association of the S1 RNA binding domain 1 (SRBD1) gene with open-angle glaucoma in various ethnic populations. However, in those studies, the definition of the patients differed, as did the results. Therefore, the relevance of the SRBD1 gene to normal tension glaucoma (NTG) appears uncertain at present. Thus, we investigated the relationship between the SRBD1 gene and NTG in a Korean NTG cohort.In total, 159 unrelated Korean patients with NTG and 103 Korean control subjects were recruited. Thus, a total of 262 participants were analyzed for SRBD1 (rs3213787 and rs11884064) gene polymorphisms.The minor allele frequency of rs3213787 was found to be 0.13 and 0.19 in NTG cases and controls, respectively. The genetic association analysis of SNP rs3213787 revealed no significant difference in genotype distribution between NTG cases and controls in allelic (odds ratio [OR] = 0.634, P = .063), dominant (OR = 0.589, P = .066) or recessive models (OR = 0.639, P = .7716). The minor allele frequency of rs11884064 was found to be 0.24 and 0.25 in NTG cases and controls, respectively. For rs11884064, no significant difference in genotype distribution was observed between NTG cases and controls in allelic (OR = 0.938, P = .755), dominant (OR = 0.927, P = .798) or recessive models (OR = 0.920, P = 1.000).The current study suggested that SRBD1 gene polymorphisms (rs3213787 and rs11884064) may not be associated with genetic susceptibility to NTG in a Korean cohort.
