RNA-sequencing data for 923 enhancer deletion newborn mouse whole skin

We examined the RNA expression profiles of whole skin from newborn CRISPR-edited mice that have the 923 enhancer located within the Epidermial Differentiation Complex deleted. We examined two independent deletion lines, 923del and 923large, both homozygous mutants and heterozygotes, as well as wild type mice and involucrin Ivl knockout mice. We find that Ivl, the gene most proximal to 923, is downregulated upon the loss of the enhancer in both independent deletions, and 4 additional genes are also downregulated in both deletion lines, a secondary effect of the loss of Ivl, as concluded by comparing to the Ivl KO mice. We thus conclude that Ivl is the primary target gene of the 923 enhancer and establish a 923-Ivl regulatory module.
