Functional Analysis of CNS DNase I Hypersensitivity Sites in the DSCAM Deletion
(A) Schematic of the 14 kb DSCAM deletion observed in family 11572. The diagram illustrates the 12 DNase I hypersensitivity sites (HSs) contained within the deletion, as well as the nine sequence intervals encompassing them. These sequence intervals were tested for their potential to direct reporter expression.
(B–D) Bright-field images of representative 48 hpf mosaic zebrafish embryos injected with DSCAM-6 (B), DSCAM-2 (C), and DSCAM-1 (D).
(E–G) tdTomato expression in representative 48 hpf mosaic embryos injected with DSCAM-6 (E), DSCAM-2 (F), and DSCAM-1 (G). Expression was seen in the forebrain (E–G), hindbrain (E–G), midbrain (E and F), spinal cord (F and G), and amacrine cells (F and G).
