F2 and Arterial thrombosis: Table 3 shows association results for genetic variants known to have a functional impact on the corresponding gene product and to be associated with venous/arterial thrombosis, i.e.,: (i) the Leiden mutation in the F5 gene (rs6025; p.Arg506Gln); (ii) the variant located in the 3′ untranslated region of the prothrombin gene (known as G20210A, rs1799963); and (iii) the missense variant p.Val34Leu in the F13A1 gene (rs5985) [37].
