چکیده

background: as a dna repair protein, flap endonuclease 1 is a key enzyme in maintaining genomic instability and preventing carcinogenesis. two single nucleotide polymorphisms (snps), -69g>a and 4150g>t are associated with dna damage. this meta-analysis is to evaluate the genetic effects of fen1 gene snps (-69g/a and 4150g/t) and the susceptibility to diseases, including glioma risk, breast cancer, lung cancer, keratoconus (kc) and fuchs’ endothelial corneal dystrophy (fecd). methods: a literature search of pubmed and embase was conducted to identify all eligible published studies. five case-control studies were included with a total of 5612 cases and 6703 controls in this meta-analysis. crude odds ratios (ors) with their corresponding confidence intervals (95%ci) were used to assess the strength of the association. results: the fen1 -69g/a and 4150g/t polymorphisms were significantly associated with the disease risk. our meta-analysis showed the fen1 -69gg genotype was correlated to increase risk for the contained diseases compared with the -69ag genotype (or=0.77, 95%ci=0.71~0.83). moreover, the fen1 4150gg genotype could increase diseases risk compared with the 4150tg genotype (or=0.81, 95%ci=0.75~0.87). conclusion: the variant genotypes of the fen1 -69g/a and fen1 4150g/t polymorphisms may be associated with diseases susceptibility. however, more studies are needed to detect the disease risk in different ethnic populations.

Association between Thrombophilic Genes Polymorphisms and Recurrent Pregnancy Loss Susceptibility in the Iranian Population: a Systematic Review and Meta-Analysis

Studies have indicated that thrombophilic genes polymorphisms are associated with recurrent pregnancy loss (RPL) in the Iranian population. We aimed to evaluate the precise association between thrombophilic genes polymorphisms (MTHFR C677T, MTHFR A1298C, Prothrombin G20210A, FVL G1691A, and PAI-1 4G/5G) and RPL risk in the Iranian population.

Association of miR-146a rs2910164 and miR-27a rs895819 polymorphisms with type 2 diabetes susceptibility: A Meta-Analysis

Background and Aim: Several investigations have evaluated the association of miR-146a rs2910164 and miR-27a rs895819 single-nucleotide polymorphisms with susceptibility to type 2 diabetes (T2D). However, the findings are conflicting and inconclusive. Therefore, this meta-analysis performed to investigate the association between these polymorphisms and T2D risk. Methods: Studies were identifie...

Association of Survivin Polymorphisms with Tumor Susceptibility: A Meta-Analysis

BACKGROUND The survivin polymorphisms have been shown to confer genetic susceptibility to various tumors, but the results are inconsistent. In order to accomplish a more precise estimation of the relationship, a meta-analysis was performed. RESULTS For rs9904341, a significantly increased tumor risk was found in overall meta-analysis under C/C vs. G/G (OR = 1.40, 95% CI = 1.13-1.74, p = 0.002...
