Erratum in van 't Hooft et al. Two common functional polymorphisms in the promoter region of the coagulation factor VII gene determining plasma factor VII activity and mass concentration. Blood. 1999;93:3432-3441.

In the article by van 't Hooft et al entitled “Two common functional polymorphisms in the promoter region of the coagulation factor VII gene determining plasma factor VII activity and mass concentration,” which appeared in the May 15, 1999, issue ofBlood (93:3432–3441), two primers were switched. In “Materials and methods,” “Genotyping,” under the second method for detecting −401G/T and −402G/A polymorphisms, the primer for the first PCR reaction should have been “5-AGGAGAAAGGTCAGGTGACC” and the primer for the second PCR reaction should have been “5-GTTAAGGTGTGTGTGGCACC.”
