Abstract
OBJECTIVE
Previous studies indicated that the relationship between lysyl oxidase-like 1 (LOXL1) gene polymorphisms and primary open-angle glaucoma (POAG) remains inconsistent. In the present study, we aimed to perform a meta-analysis to investigate the association of LOXL1 polymorphisms with POAG risk.
METHODS
Literatures were electronically searched in the PubMed, EMBASE, CNKI, Wanfang, and VIP databases. The published literatures, which are case-control or cohort studies on the relationship between the polymorphisms (rs1048661, rs3825942, rs2165241) of the LOXL1 gene and POAG, were documented.
RESULTS
We included 13 literatures including 5,293 subjects for the present study. A meta-analysis showed that the risk of POAG in individuals carrying the C allele of rs2165241 was 1.26 times higher compared with those carrying the T allele (odds ratio (OR)=1.26, 95% confidence interval (CI): 1.09~1.46) in the total population. In the Caucasian population, we also found that individuals carrying the C allele of rs2165241 have an increased risk for POAG compared to those subjects carrying the T allele (OR=1.42, 95% CI: 1.19~1.69, p=0.0001). In addition, we found that the rs1048661 polymorphism was associated with POAG in the Asian population (OR=1.17, 95% CI: 1.02~1.35, p=0.03), and rs3825942 was associated with POAG in the Caucasian population (OR=2.69, 95% CI: 1.61~4.47, p<0.001).
CONCLUSIONS
The polymorphisms of the LOXL1 gene were associated with the susceptibility of POAG.
