Associate Professor of MedicineUniversity of WashingtonAssociate Member, Bloodworks NorthWestFaculty Information Biography Dr. Johnsen is a physician scientist with expertise in classical (benign) hematology. She sees patients in the Washington Center for Bleeding Disorders (WCBD) at Bloodworks Northwest (BWNW). Dr. Johnsen studies the genetics and biology of clotting factors and blood groups (blood types), with emphasis on coagulation factor VIII (FVIII), factor IX (FIX), and von Willebrand factor (VWF), and clinically relevant blood group genes, particularly in the ABO and Rh systems. Dr. Johnsen’s research takes new next generation sequencing approaches to identify genetic/genomic variation in genes responsible for hemostasis and the expression blood types. These studies have found (and continue to find) a wide variety of simple, complex, rare, and novel DNA changes in coagulation factor and blood group genes. Findings from this work informs functional studies of the consequences of DNA changes in these genes to better understand causes of disease and to improve interpretation of genetic data. Dr. Johnsen is further working to better understand the molecular basis of how inherited bleeding disorders uniquely impact females, particularly in hemophilia and von Willebrand disease.
