Genetic polymorphism (Arg353-->Gln) in coagulation factor VII gene and factor VII levels (coagulant activity, antigen and binding ability to tissue factor) in 101 healthy Japanese.
We studied the frequency of the Msp I genotype (Gln353) for factor VII in 101 young healthy Japanese individuals, and the levels of factor VII-related procoagulant activity (FVII:c), antigen (FVII:ag) and binding ability to tissue factor (FVII-TF binding). The frequency of the allele coding for the factor VII Gln353 was 0.05 among this group. Individuals with genotype M1M1 had an FVII:c of 103.52 +/- 17.85% (mean +/- SD), FVII:ag of 102.50 +/- 18.42% (mean +/- SD) and FVII-TF binding of 101.03 +/- 22.22% (mean +/- SD). Triglyceride levels of subjects with the M1M1 genotype were 84.34 +/- 44.97 mg dl-1 (mean +/- SD). FVII:c (50%), FVII:ag (45%) and FVII-TF binding (36%) from an individual with the M2M2 type was the lowest, with a triglyceride value of 39 mg dl-1. On the other hand, individuals with the genotype M1M2 had an FVII:c of 75.57 +/- 9.61% (mean +/- SD), FVII:ag of 72.43 +/- 8.54% (mean +/- SD) and FVII-TF binding of 68.14 +/- 14.91% (mean +/- SD). FVII:c, FVII:ag and FVII-TF binding in individuals with the M1M2 and M2M2 genotypes were significantly lower than those in individuals with the M1M1 genotype.
