Plasma FXIII mass concentration in healthy populations with different FXIII Val34Leu genotypes.

(A) Frequency distribution of plasma FXIII concentration (n = 189). Normal distribution was verified by 2 different statistical tests. The ideal normal distribution is indicated. (B) Means and standard deviations of FXIII concentrations in groups of healthy controls with different FXIII Val34Leu genotypes and in the total population. There were no statistically significant differences among the groups with different genotypes or between each of these groups and the total population.
