1 - 55 . (canceled)
56 . A method for treating Canavan disease in a subject, the method comprising:
intrathecally, intraventricularly, or intravascularly administering rAAV to the subject in an amount effective for transducing oligodendrocytes of the subject with the rAAV, wherein the rAAV comprises
(i) a capsid protein having the amino acid sequence of SEQ ID NO: 8 and
(ii) a nucleic acid comprising a promoter operably linked with a region encoding aspartoacylase (ASPA), wherein the ASPA is expressed from the nucleic acid in oligodendrocytes transduced by the rAAV.
57 . The method of claim 56 , wherein the nucleic acid expresses an aspartoacylase (ASPA) mRNA comprising one or more miRNA binding sites for one or more miRNAs that are more abundant in one or more non-CNS tissues in comparison to a CNS tissue.
58 . The method of claim 57 , wherein the one or more miRNAs that are more abundant in one or more non-CNS tissues in comparison to the CNS tissue are at least twofold more abundant.
59 . The method of claim 57 , wherein the one or more non-CNS tissue is not kidney tissue or retinal tissue.
60 . The method of claim 56 further comprising evaluating kidney function in the subject at least once after the administration.
61 . The method of claim 56 further comprising evaluating vision of the subject at least once after the administration.
62 . The method of claim 56 , wherein the rAAV is administered intrathecally to the subject.
63 . The method of claim 56 , wherein the rAAV is administered intraventricularly to the subject.
64 . The method of claim 56 , wherein the rAAV is administered intravascularly to the subject.
