Hemophilia B & the story of Tsarevich Alexei - Part 1 Global Hemophilia Report

Hemophilia B is a rare inherited X-linked disorder characterized by a congenital anomaly in the factor IX gene leading to a variable deficiency in clotting factor IX. In this episode, we explore the known differences between Hemophilia B and Hemophilia A and discuss priority areas for further research into Hemophilia B. The episode also guides listeners on an entertaining journey through 19th and 20th century European monarchy and the unlikely role that hemophilia played in forever shaping Europe’s governance!
