Genotypes and allele frequencies of other previously reported polymorphisms that associated with thrombotic diseases [fibrinogen Bβ Arg448Lys (rs420), fibrinogen Bβ −148C/T (rs1800787), fibrinogen Bβ −455G/A (rs1800790), prothrombin 19911A/G (rs3136516), plasminogen activator inhibitor-1 (PAI-1 4G/5G, rs1799768), tissue plasminogen activator 7351C/T (t-PA, rs2020918)] did not show a difference between CTEPH and control/PTE [20 21]. The gene discussed is PLAT; the disease is thrombotic disease.
