Abstract
Aspects of the disclosure relate—compositions and methods useful for delivering minigenes—a subject. Accordingly, the disclosure is based, in part, on isolated nucleic acids and gene therapy vectors, such as viral (e.g., rAAV) vectors, comprising one or more gene fragments encoding a therapeutic gene product, such as a protein or peptide (e.g., a minigene). In some embodiments, the disclosure relates to gene therapy vectors encoding a ABCA4 protein (e.g., the gene product of ABCA4 gene) or a portion thereof. In some embodiments, compositions described by the disclosure are useful for treating diseases associated with mutations in the ABCA4 gene, for example, Stargardt disease.
Claims21
A method of increasing the thickness of the outer nuclear layer (ONL) of a retina of a subject in need thereof, the method comprising administering to the retina of the subject an adeno-associated virus (AAV) vector comprising a transgene encoding an ABCA4 minigene encoding the amino acid sequence set forth in any one of SEQ ID NOs:
- 9-14 and 20-24.

(canceled)
A method of maintaining outer nuclear layer (ONL) thickness in the retina of a subject in need thereof, the method comprising:
- administering to the retina of the subject an adeno-associated virus (AAV) vector comprising a transgene encoding an ABCA4 minigene encoding the amino acid sequence set forth in any one of SEQ ID NOs:
- 9-14 and 20-24, wherein administration of the AAV vector to the retina is effective in maintaining ONL thickness;
- and
- assessing lipofuscin and/or A2E concentration in the retina of the subject,
- wherein a decrease in lipofuscin and/or A2E concentration indicates maintenance of ONL thickness.
