The normal tissue tropism of adeno-associated virus (AAV) is poorly defined, although the majority of humans test seropositive for this virus. Eighty-five muscle biopsy specimens were tested for AAV genomes; AAV DNA was identified in 17% of normal and 10% of Duchenne muscular dystrophy muscle biopsy specimens, but in only 3% of peripheral blood samples. AAV genomes were absent from all 37 muscle biopsy specimens from patients with myositis tested. Muscle is a major target organ for AAV, and infection is associated with autoimmune disease of muscle.
