Reduced clinical severity in a mutationally well-characterized cohort of severe hemophilia with associated thrombophilia. [Journal Article]
Am J Clin Pathol 2008 Jul; 130(1):84-7.
The clinical phenotype in hemophilia generally correlates with the type of mutations. We studied 16 patients with severe hemophilia A (factor VIII and factor VIII:Ag <1%) with intron 22 inversions of the factor VIII gene and 6 patients with hemophilia B, 2 each having a common mutation, for the common prothrombotic markers in the anticoagulant and fibrinolytic cascade. Of the patients, 6 of 10 with "clinically mild" and 1 of 12 with "clinically severe" disease had a deficiency or abnormality of any of the factors studied. Thrombophilia thus modulates the clinical severity of hemophilia as is observed in patients who carry similar mutations.
