Elevated factor VII coagulant activity (FVII:C) has been associated with an increased risk of ischaemic heart disease, particularly for fatal events. Results of studies on the association between FVII:C and atherosclerosis are not consistent. FVII:C levels are influenced by several environmental factors and by genetic factors. One of the genetic factors is the -323Ins10 polymorphism in the promoter region of the factor VII gene, which is strongly related to FVII:C, and thus may be associated with ischaemic heart disease. We studied the association of this polymorphism with the severity and progression of atherosclerosis. In 511 male patients of the Regression Growth Evaluation Statin Study, the genotype for the -323Ins10 polymorphism was determined. The minimum obstruction diameter and the mean segment diameter were determined at baseline and after a 2-year follow-up period, and new lesion formation was assessed as well. Cardiovascular events were recorded. No relationship was observed between the -323Ins10 polymorphism and angiographic measures of disease progression, nor on the risk of new cardiovascular events. The results suggest that there is no association between the -323Ins10 polymorphism for factor VII and the severity or progression of coronary atherosclerosis in male patients with symptomatic coronary artery disease.

Objective: : Coagulation factor VII (FVII) triggers the extrinsic pathway of blood coagulation. In our previous study, we showed that FVII plays an important role in tumorigenesis of hepatocellular carcinoma (HCC). However, the role of FVII polymorphism in HCC is still unknown.

Background: Pathogenesis of intraventricular hemorrhage (IVH) in premature infants is multifactorial. Little is known about the impact of genetic variants in the vitamin K-dependent coagulation system on the development of IVH.
Methods: Polymorphisms in the genes encoding vitamin K epoxide reductase complex 1 (VKORC1 -1639G>A) and coagulation factor 7 (F7 -323Ins10) were examined prospectively in 90 preterm infants <32 weeks gestational age with respect to coagulation profile and IVH risk.

Background: Previous studies have examined the association between polymorphisms in the coagulation factor VII gene and the risk of coronary heart disease (CHD), but those studies have been inconclusive. This study was conducted to assess the associations between these polymorphisms and CHD and evaluated the associations in different ethnicities.
Methods: Literature-based searching was conducted to collect data and two methods, namely fixed-effects and random-effects, were performed to pool the odds ratio (OR), together with the 95% confidence interval (CI).

Unlabelled: Factor VII (FVII) plays an important role in blood coagulation. The role of common polymorphisms influencing the FVII plasma levels in thromboembolic disorders has been evaluated but there is no published data related to the effect of FVII gene polymorphisms on the venous thrombosis risk in cancer.
Aim: To investigate the association of three common functional polymorphisms in the promoter region of FVII gene: a decanucleotide insertion at position-323 (-323ins10-bp), a G to T substitution at position-401 (-401GT), and a G to A substitution at position-402 (-401GT) with venous thrombosis in cancer patients.

Background And Purpose: Recent data have shown that the hemostatic system may play a role in cancer development and progression. To test whether factor VII (FVII) can be a candidate factor for breast cancer, we have evaluated the distribution of FVII gene polymorphisms in breast cancer patients and healthy subjects.
Methods: The nested case-control study consisted of 92 women with breast cancer (group 1) and 80 control subjects (in age-matched women) (group 2).
