Previous 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.

Despite efforts to interrogate human genome variation through large-scale databases, systematic preference toward populations of Caucasian descendants has resulted in unintended reduction of power in studying non-Caucasians. Here we report a compilation of coding variants from 1,055 healthy Korean individuals (KOVA; Korean Variant Archive). The samples were sequenced to a mean depth of 75x, yielding 101 singleton variants per individual. Population genetics analysis demonstrates that the Korean ...

Purpose To investigate the associations between the non–intraocular pressure (IOP)–related genetic variants (genetic variants associated with vulnerability of the optic nerve independent of IOP) and primary open-angle glaucoma (POAG), including normal-tension glaucoma (NTG) and high-tension glaucoma (HTG), and between the non-IOP-related genetic variants and a family history of glaucoma. Design Case-control study. Methods Japanese patients with NTG (n = 213) and HTG (n = 212) and 191 control sub...

Primary open angle glaucoma (POAG) is a complex progressive optic nerve neuropathy triggered by both environmental and genetic risk factors. Several ocular tissues, including the ciliary body, trabecular meshwork and optic nerve head, and perhaps even brain tissues, are involved in a chain of pathological events leading to POAG. Genetic risk evidence for POAG came from family linkage-studies implicating a small number of disease genes (MYOC, OPEN, WDR36). Recent Genome Wide Association Studies (...

The purpose of this study was to confirm previously reported associations of common variants in or near CDC7/TGFBR3, ZP4, SRBD1, ELOVL5, CAV1/CAV2, TLR4, CDKN2B, CDKN2B-AS1, ATOH7, PLXDC2, TMTC2, SIX1, and CARD10, with primary open angle glaucoma (POAG) in the Afro-Caribbean population of Barbados, West Indies. A total of 437 unrelated subjects from the Barbados Family Study of Open Angle Glaucoma (BFSG), including 272 with POAG and 165 unaffected individuals were included in this study. Eightee...

Purpose Primary open angle glaucoma (POAG) is a characteristic optic neuropathy which progresses to irreversible vision loss. Few genes have been detected that influence POAG susceptibility and other genes are therefore likely to be involved. We analyzed carefully characterized POAG cases in a genome-wide association study (GWAS).

Abstract Glaucoma is the leading cause of irreversible blindness worldwide. This review aims to provide a greater understanding of the complex genetic influences that may lead to mitochondrial dysfunction and increase susceptibility to retinal ganglion cell (RGC) loss in primary open angle glaucoma (POAG), and thus elucidate potentially important pathophysiological pathways amenable to therapeutic intervention. Emerging evidence from genome wide association and other genetic studies suggests tha...
PURPOSE: The S1 RNA binding domain 1 (SRBD1) and elongation of long-chain fatty acids family member 5 (ELOVL5) have been reported to be susceptibility genes for early-onset normal-tension glaucoma (NTG). The present study we conducted to assess whether these genes were associated with primary open-angle glaucoma (POAG), including late-onset NTG and high-tension glaucoma (HTG). METHODS: Three hundred seventy Japanese patients with POAG, including 158 NTG and 212 HTG patients and 191 control subje...

PURPOSE: Factors contributing to the development of normal tension glaucoma (NTG), degenerative optic neuropathy characterized by the progressive loss of retinal ganglion cells, optic nerve axons, and visual fields, have not been determined. To identify genetic risk factors for NTG, we performed a genome-wide association study of NTG. DESIGN: Case-control study. PARTICIPANTS: The study cohort consisted of 305 Japanese patients with NTG and 355 controls. METHODS: We genotyped 500,568 single-nucle...

Whole-genome association studies (WGAS) bring new computational, as well as analytic, challenges to researchers. Many existing genetic-analysis tools are not designed to handle such large data sets in a convenient manner and do not necessarily exploit the new opportunities that whole-genome data bring. To address these issues, we developed PLINK, an open-source C/C++ WGAS tool set. With PLINK, large data sets comprising hundreds of thousands of markers genotyped for thousands of individuals can ...

Glaucoma, the world’s leading cause of irreversible blindness, is a complex disease, with differential presentation as well as ethnic and geographic disparities. The multifactorial nature of glaucoma complicates the study of genetics and genetic involvement in the disease process. This review synthesizes the current literature on glaucoma and genetics, as stratified by glaucoma subtype and ethnicity. Primary open-angle glaucoma (POAG) is the most common cause of glaucoma worldwide, with the only...
