None of studied single genetic variants-F13A1 Val34Leu, THBS2 T/G 3'UTR and THBS4 Ala387Pro-and the extended CC/TT/GG haplotype of F13A1/THBS2/THBS4 genes was associated with MI in young age.
Also, the coagulation factor XIII (gene symbol F13A1) Val34Leu haplotype tag single nucleotide polymorphism (htSNP) has been reported to exert pleiotropic effects on serum IL-6 concentration and to be associated with risk of MI</span>.
