The human promoter was used to drive photoreceptor-specific expression of a human cDNA with a deletion of AACTT at position 790 to 794 found in patients with Stargardt-like macular dystrophy. Three lines were created (lines 1, 2, and 3) with 0.6, 3.3, and 5.3 times the level of endogenous gene expression, respectively.
