The invention relates to a recombinant adeno-associated virus (AAV) capsid protein, which is a hybrid between AAV serotype 9 (AAV9) and AAV serotype 74 (AAVrh74) capsid proteins, wherein said recombinant hybrid AAV capsid protein has a reduced liver tropism compared to the parent AAV9 and AAVrh74 capsid proteins. The invention relates also to the derived hybrid AAV serotype vector particles packaging a gene of interest and their use in gene therapy, in particular for treating neuromuscular genetic diseases.
