Clinical Info

The prothrombin (Factor II) mutation refers to a base change from guanine (G) to adenine (A) at nucleotide position 20210 in the prothrombin gene. The G20210A mutation is associated with an elevation of prothrombin levels to about 30 percent above normal in heterozygotes and to 70 percent above normal in homozygotes. The mutation is the second most common inherited risk factor for thrombosis. In the United States, the prevalence of the mutant allele is 1.1 percent in Caucasians and Hispanics and 0.3 percent in African Americans. This mutation is present in about 2 percent of the population and in 6 percent or more of patients who present with a first venous thromboembolism (VTE).
