Abstract:
OBJECTIVEThe -455 G/A (HaeIII) polymorphism of beta-fibrinogen gene influences levels of plasma fibrinogen. We further investigated whether it influences the risk of ischemic cerebrovascular disease.
METHODSWe accumulated 134 acute ischemic cerebrovascular disease (ICVD) cases and compared their -455 G/A status with a control group (n = 166). The beta-fibrinogen gene -455 G/A polymorphism was analyzed for all subjects by PCR-RFLP with the restrictive enzyme HaeIII.
RESULTSPlasma fibrinogen was higher in AA homozygous participants (341 mg/dL) than in participants carrying the G allele: GA (290 mg/dL), GG (298 mg/dL) in the control group. Plasma fibrinogen was also higher in AA homozygous patients (353 mg/dL) than in cases carrying the G allele: GA (287 mg/dL), GG (302 mg/dL) in the ICVD group. However, there was no significant association between beta-fibrinogen gene -455 G/A polymorphism and ICVD group.
CONCLUSIONSAlthough a small effect cannot be excluded, beta-fibrinogen gene -455 G/A polymorphism is an independent predictor of plasma fibrinogen, but not of ischemic cerebrovascular disease.
