Abstract

Official abstract text for this publication.

Methods and compositions for gene therapy of retinal degeneration related to mutations in nicotinamide mononucleotide adenylyltransferase 1 (NMNAT1).

First claim

Opening claim text (preview).

What is claimed is: 1. A method of treating retinal degeneration caused by mutations in a nicotinamide mononucleotide adenylyltransferase 1 (NMNAT1) gene in a human subject, the method comprising delivering to an eye of the subject a therapeutically effective amount of an Adeno-associated virus 2/9 (AAV2/9) vector comprising a sequence encoding a functional human NMNAT1, operably linked to a CASI promoter that drives expression in photoreceptors, wherein the sequence encoding the functional human NMNAT1 is at least 98% identical to SEQ ID NO: 1. 2. The method of claim 1 , wherein the sequence encoding the functional human NMNAT1 is codon optimized. 3. The method of claim 1 , wherein the vector is delivered via sub-retinal injection. 4. The method of claim 1 , wherein the vector is self-complementary AAV2/9 (scAAV2/9). 5. The method of claim 1 , wherein the sequence encoding the functional human NMNAT1 is at least 99% identical to SEQ ID NO: 1. 6. The method of claim 1 , wherein the sequence encoding the functional human NMNAT1 comprises SEQ ID NO:1. 7. The method of claim 1 , wherein the vector further comprises a 3′ bovine growth hormone untranslated region. 8. A method of increasing expression of NMNAT1 in photoreceptor cells in an eye of a human subject, the method comprising delivering to the eye of the subject a therapeutically effective amount of an Adeno-associated virus type 2/9 (AAV2/9) vector comprising a sequence encoding a functional human NMNAT1, operably linked to a CASI promoter that drives expression in the photoreceptor cells, wherein the subject has retinal degeneration caused by a mutation in a nicotinamide mononucleotide adenylyltransferase 1 (NMNAT1) gene, wherein the sequence encoding the functional human NMNAT1 is at least 97% identical to SEQ ID NO: 1. 9. The method of claim 8 , wherein the vector is delivered via sub-retinal injection. 10. The method of claim 8 , wherein the vector is self-complementary AAV2/9 (scAAV2/9). 11. The method of claim 8 , wherein the sequence encoding the functional human NMNAT1 is at least 98% identical to SEQ ID NO:1. 12. The method of claim 8 , wherein the sequence encoding the functional human NMNAT1 is at least 99% identical to SEQ ID NO: 1. 13. The method of claim 8 , wherein the sequence encoding the functional human NMNAT1 comprises SEQ ID NO:1. 14. An Adeno-associated virus type 2/9 (AAV2/9) vector comprising a sequence encoding a functional human NMNAT1, operably linked to a CASI promotor that drives expression in photoreceptor cells, wherein the sequence encoding the functional human NMNAT1 is codon at least 98% identical to SEQ ID NO: 1. 15. The AAV2/9 vector of claim 14 , wherein the vector is a self-complementary AAV2/9 (scAAV2/9). 16. The AAV2/9 vector of claim 14 , wherein the sequence encoding the functional human NMNAT1 is at least 99% identical to SEQ ID NO:1. 17. The AAV2/9 vector of claim 14 , wherein the sequence encoding the functional human NMNAT1 comprises SEQ ID NO:1. 18. A pharmaceutical composition comprising the vector of claim 14 , formulated for delivery via sub-retinal injection.
