Background. G to A mutations at positions 20210 of the prothrombin gene (F2
) and 1691 of the factor V gene (F5) are established risk factors for venou
s thrombosis. Several factors associated with coagulation and/or fibrinolys
is have been associated with arterial occlusive disease, but the role of F2
20210A and F5 1691A for arterial occlusive disease remains unclear. Object
ive. To investigate if F2 20210A and F5 1691A are associated with periphera
l arterial occlusive disease (PAOD). Methods and Results. We analyzed the p
revalence of F2 20210A and F5 1691A alleles in 336 patients with documented
PAOD at Fontaine stage LI - IV and 300 controls without vascular disease.
Allele frequencies in patient!, and controls were 0.013 and 0.022 for F2 20
210A, and 0.042 and 0.045 for F5 1691, respectively, both differences being
not statistically significant. Conclusion. Our data suggest that mutations
F2 G20210A and F5 G1691A are not associated with PAOD.
