  1. Coagulation factor VII, serum-triglycerides and the R/Q353 polymorphism : Differences between older men and women.

    Article - En anglais

    Coagulation factor VII activity (FVII : C) is a risk indicator for cardiovascular disease.

    It is related to serum-triglycerides and the R/Q353 polymorphism (alleles R and Q) in the gene coding for factor VII is strongly associated with factor VII.

    The association of serum-triglycerides with factor VII may differ between the genotypes, but the results of earlier studies were inconsistent and did not include older people.

    We studied FVII, triglycerides and the R/Q353 polymorphism in the Rotterdam Study.

    In 1158 older subjects (489 men and 669 women) FVII : C, factor Vll : Chr, serum-triglycerides and the R/Q353-genotype were determined.

    In women triglycerides were positively associated with FVII : Chr and FVII : C (FVII : Chr : bêta=12.4% PP/mmol/L, Cl : 10.3-14.5 ; FVII : C : bêta=13.1% PP/mmol/L, Cl : 10.4-15.8).

    These associations varied by genotype (FVII : Chr : RR : bêta=11.7, Cl : 9.6-13.8, RQ/QQ : bêta=7.9, Cl : 4.6-11.2 ; FVII : C : RR : bêta=12.5, Cl : 9.5-15.5, RQ/QQ : bêta=6.4, Cl : 1.4-11.4).

    In men, the associations of FVII : Chr and FVII : C with triglycerides were weaker (FVII : Chr : bêta=5.9, CI : 4.1-7.7 ; FVII : C : bêta=8.7, Cl : 6.2-1 1.2).

    There was no difference between the genotype groups.

    These results suggest that only in older women the strength of the association of factor VII with serum-triglycerides varies according to genotype of the R/Q353 polymorphism.
