Mutations in large genes are a frequent cause of inherited retinal diseases, and can result in severe visual impairment. However, as the causative genes exceed the cloning capacity of the most currently used viral vector to date, developing a gene replacement therapy is challenging. As part of a European network of 7 laboratories, we aim to meet this challenge and develop an alternative therapeutic strategy for large disease-causing genes in human retinal organoids derived from patient induced pluripotent stem cells (iPSCs).

The applicant will join the “Gene therapy of inherited retinal dystrophies” group within the Vision team of the INM ( This dynamic group is interested in developing innovative strategies to treat genetic retinal diseases.
