Abstract

Se provee un método para la edición dirigida de ARN diana que contiene una mutación G a A en un transcrito de gen USH2A con base en tecnología LEAPER, que comprende: introducir un constructo de un ARN de reclutamiento de adenosina desaminasa (arARN) para editar el ARN diana o un constructo que codifica dicho arARN en una célula, en donde el arARN comprende una secuencia de ARN complementaria que se hibrida al ARN diana, y en donde el arARN es capaz de reclutar adenosina desaminasa que actúa en el ARN (ADAR), de modo que la adenosina diana en el ARN diana es desaminada, realizando de este modo la edición in vivo de la base de A a I en el ARN de manera segura y eficaz, reparando un sitio de mutación patogénica, y logrando el propósito de tratar una enfermedad tal como el síndrome de Usher.
