HCV

The HCV is first identified; it soon becomes clear that an even higher proportion of people with hemophilia have been exposed to this virus, which can result in chronic liver disease.

Gene Isolation

Isolation of the genes controlling factor VII and von Willebrand's factor production. (Factor VII deficiency results in a rare form of hemophilia, but also may have broad applications in treating more common forms of hemophilia.)

LAV to HIV

CDC Morbidity and Mortality Weekly Report (MMWR) reported 72% of severe asymptomatic hemophiliac had antibody to LAV antigens using the Western blot test. This virus is now known to be a member of the HIV-1 group of viruses.
