Abstract
Previous work has suggested that ischemic stroke (IS) may be more likely to occur in individuals with a genetic predisposition. In this study, we investigated the potential association of IS-relevant genetic risk factors with cardioembolic stroke (CES) in atrial fibrillation (AF) patients with low CHA2DS2-VaSc score. Genotyping was performed using the GenomeLab SNPstream genotyping platform for five IS-relevant SNPs (MMP-9 C1562T, ALOX5AP SG13S114A/T, MTHFR 677 C/T, FGB 455 G/A, and eNOS G298A) in 479 AF patients with CES and 580 age and sex-matched AF patients without CES. The multivariate analysis adjusted for potential confounders and demonstrated that FGB 455 G/A was independently associated with increased risk of CES in AF patients and the significance remained after Bonferroni correction in the additive, dominant, and recessive models with ORs of 1.548 (95% CI: 1.251–1.915, P = 0.001), 1.588 (95% CI: (1.226–2.057, P = 0.003), and 2.394 (95% CI: 1.357–4.223, P = 0.015), respectively. Plasma fibrinogen levels were significantly higher in patients with the A allele compared with patients with genotype of GG (3.29 ± 0.38 mg/dl vs. 2.87 ± 0.18 mg/dl, P < 0.001). We found for the first time that the A allele of FGB 455 G/A was a risk factor for CES in AF patients, probably by elevating the level of plasma fibrinogen.

Abstract
The most important complications of Philadelphianegagive (non BCR-ABL) myeloproliferative neoplasms (MPNs) are vascular events. Our aim was to evaluate the effects of single nucleotide polymorphisms (SNPs), platelet glycoproteins (GPs) (Ia/IIa, Ibα, IIb/IIIa and VI), von Willebrand factor (vWF), coagulation factor VII (FVII), β-fibrinogen, and the risk of thrombosis in patients with non BCR-ABL MPNs at the Lithuanian University of Health Sciences. Kaunas, Lithuania. Genotyping was done for 108 patients. The TT genotype of the GP Ia/IIa c.807C>T polymorphism was more frequently found in the group of MPN patients with arterial thrombosis compared to MPN patients who were thrombosis-free [26.5 vs. 11.5%, p = 0.049; odds ratio (OR) 2.68; 95% confidence interval (95% CI) 1.01-7.38]. The CT genotype of the β-fibrinogen c.-148C>T polymorphism occurred more frequently in MPN patients with arterial, and total thrombosis compared to the wild or homozygous genotype (57.7 vs. 40.0 vs. 12.5%; p = 0.027), (64.7 vs. 44.4 vs. 25%; p = 0.032), respectively. The carrier state for the c.-323P10 variant of FVII SNP (summation of P10/10 and P0/10) was more frequent in MPN patients with thrombosis compared to the wild-type genotype carriers (71.4 vs. 43.4%; p = 0.049; OR 3.26; 95% CI 1.01-11.31). The coexistence of heterozygous β-fibrinogen c.-148C>T and FVII c.-323P0/10 SNP, increased the risk of arterial thrombosis (21.1 vs. 3.7%, p = 0.008; OR 6.93; 95% CI 1.38-34.80). The TT genotype of GP Ia/IIa c.807C>T, the CT genotype of β-fibrinogen c.-148C>T and FVII c.-323P0/10 SNP could be associated with risk of thrombosis in MPN patients.

Genetic polymorphism of β-fibrinogen gene-455G/A can contribute to the risk of ischemic stroke. Neurol Sci 2013; 35:151-61. [PMID: 24366241 DOI: 10.1007/s10072-013-1608-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2013] [Accepted: 12/11/2013] [Indexed: 10/25/2022]
Abstract
Many studies have investigated the association between the β-fibrinogen gene-455G/A (FGβ-455G/A) polymorphism and the risk of ischemic stroke. However, these evidences were inadequate to provide stronger conclusions because most studies were generally small. To shed light on these inconclusive findings, we conducted a large sample size meta-analysis of studies relating to the FGβ-455G/A polymorphism and the risk of ischemic stroke. Odds ratios with a 95 % confidence interval were used to investigate the association between FGβ-455G/A polymorphism and ischemic stroke. Publication bias was tested by Egger's test and funnel plot. Inconsistency index and Cochran's Q statistic were used to check heterogeneity. Cumulative and recursive cumulative meta-analyses were performed to provide a framework for updating a genetic effect from all of the included studies. Twenty-six independent publications with 4,070 cases and 4,649 controls were included in this meta-analysis. Results showed that the β-fibrinogen-455G/A polymorphism was significantly associated with the risk of ischemic stroke. The FGβ-455G/A polymorphism was found to be a risk factor for ischemic stroke in Asians and adults, while association was not observed for Caucasians and juveniles based on the small size and it may be necessary to conduct larger studies on them to investigate the association in the future. The cumulative meta-analysis indicated a decline from 1998 to 2003, and the results remained stable during the period 2004-2012. The results indicate that FGβ-455G/A polymorphism may be a susceptible predictor of ischemic stroke. More studies are needed to elucidate the relationship further.
