  • Description: Tamoxifen inducible ablation of arachidonate 12-lipoxygenase (Alox12b) in epidermis (and other K14 expressing tissues). Alox12b plays a crucial role in the synthesis of corneocytes lipid envelope and the establishment of the skin barrier to water loss. Ichthyosis, congenital, autosomal recessive 2 (ARCI2). Ichthyosis is a family of rare genetic skin disorders characterised by dry, thickened, scaly skin.
