Researchers design factor IX variants for short- and long-term Hemophilia B management

After blood vessel damage, effective blood clotting is essential to halt bleeding. However, this process is inefficient in some individuals due to hereditary factors. Hemophilia B, for example, results from a deficiency in coagulation factor IX (FIX), which can lead to prolonged bleeding after injuries or surgery.
