Among the target genes for miR-6240-5p, we found two genes associated with RP, Klhl23 and Nr2e3, and one with retinoschisis, Rs1. Another noteworthy target for miR-6240 was Nxnl2, which has been suggested to be involved in the maintenance of both the function and the viability of sensory neurons, including photoreceptors.68,69. Here, KLHL23 is linked to retinitis pigmentosa 1.
