A recent study described patient derived induced pluripotent stem cell (iPSC) treatment with clustered regularly interspersed short palindromic repeats (CRISPR/Cas9) to treat a RP affected patient with an X-linked point mutation in the retinitis pigmentosa GTPase regulator (RPGR) gene [4] in addition to other attempts to treat retinal dystrophies. Here, RPGR is linked to Retinal dystrophy.
