AAV vector for gene therapy
First Claim
1. A method of gene therapy in a heart muscle tissue of a patient, comprising delivering to the heart muscle tissue of a patient an AAV-2 vector or an AAV-2 particle having a capsid encoded by the AAV-2 vector, wherein the AAV-2 vector comprises mutations R484E and R585E according to the numbering based upon VP1 protein, which are in a heparin binding motif of a capsid protein and cause a reduced or eliminated heparin binding function, and wherein said mutations are located on different subunits of the capsid protein.

Abstract
Described are recombinant AAV vectors characterized in that they carry capsid protein modification(s) resulting in a reduced or eliminated heparin binding function. The AAV vectors of the present invention are particularly suitable for gene therapy by systemic application, since (a) transduction of the liver is eliminated or at least drastically reduced and (b) the transduction efficiency of non-hepatic tissues is increased.
