A loxP site was inserted upstream of exon 2. Exon 3 was replaced with one in which a C to G transversion and a neo cassette flanked with FRT and loxP sites. Flp-mediated recombination removed the neo cassette. The point mutation replaces serine with an arginine at position 163 (S163R). This mutation corresponds with the human mutation associated with late-onset retinal macular degeneration (L-ORD). (J:171089)
