A. Corral et al., THE VENOUS THROMBOSIS RISK FACTOR 20210-A-ALLELE OF THE PROTHROMBIN GENE IS NOT A MAJOR RISK FACTOR FOR ARTERIAL THROMBOTIC DISEASE, British Journal of Haematology, 99(2), 1997, pp. 304-307
A nucleotide change (G to A transition) at position 20210 has recently
been demonstrated to be a risk factor for venous thrombosis. The rele
vance of this polymorphism to thrombotic disease was investigated by g
enotypic identification in three prospective case-control studies: 101
case patients with acute coronary heart disease (CHD), 104 patients w
ith acute cerebrovascular disease (CVD), 82 patients with a confirmed
diagnosis of deep venous thrombosis (DVT), and one control age-and sex
-matched for each patient. The prevalence of the genetic variation was
significantly associated with the occurrence of DVT, but did not diff
er in patients with CHD or CVD from that in controls, suggesting that
this allele should not be considered a major risk factor for arterial
thrombotic disease.
