FIELD: biotechnology.
SUBSTANCE: group of inventions including a method of treating a person suffering from hemophilia A (variants) is described. In one embodiment, the method includes administering to a person having hemophilia A recombinant adeno-associated virus (rAAV) vector, wherein the vector genome includes a nucleic acid variant encoding factor VIII (FVIII) having a B-domain deletion (hFVIII-BDD), wherein the nucleic acid variant has 95% or greater identity with SEQ ID NO:7.
EFFECT: invention expands the arsenal of methods of treating hemophilia A leading to the absence of spontaneous bleeding in a person for at least 1 year.
