Abstract

Oculocutaneous albinism type 1 (OCA1) is a hypopigmentation disorder caused by biallelic loss of functional variants in the tyrosinase (TYR) gene. Gene augmentation therapies often
utilize adeno-associated viral (AAV) vectors to deliver non-mutated minigenes for immediate and
long-lasting rescue of the gene function and phenotype. This study follows this template for a
proof-of-concept assessment, creating an AAV2-derived 7m8 capsid virus containing a functional
TYR gene cargo and infecting HEK293 cells in vitro for gene transfer and expression analysis. Overall, results showed an effective 2.1-fold higher upregulation of TYR in infected cells in comparison to untreated wild-type cells, confirming the successful delivery of the functional gene via an AAV vector. Current and potential delivery and treatment methods are also evaluated, as they are widely versatile and show promising potential for albinism and other inherited diseases.
