Oculocutaneous albinism (OCA) is the most common hereditary cause of generalized hypopigmentation, which results in severe visual deficits in patients. Molecular links between genetic defects, developmental pathways and clinical signs remain poorly understood, especially with regards to the pathophysiology of the ocular defects. As part of an ANR-funded national collaborative project (OCAGEN), we aim to unravel the molecular mechanisms impacting pigmented cells and ocular disease outcome by combining the state-of-the-art techniques of iPSC and CRISPR/Cas genome editing. The selected candidate will generate iPSC lines knocked-out for 5 different albinism genes and differentiate them into iPSC-derived retinal pigment epithelium and organoids. He/She will study these human retinal models at the morphological, functional and biochemical levels to elucidate the role of OCA genes in disease pathophysiology.

The applicant will join the “Gene therapy of inherited retinal dystrophies” group within the Vision team of the INM (http://www.inmfrance.com/inmfrance-j3/index.php/en/vision-en). This dynamic group is interested in developing innovative strategies to treat genetic retinal diseases
