MGI Phenotype FUNCTION: This gene encodes an enzyme involved in the conversion of arachidonic acid to 12R-hydroxyeicosatetraenoic acid. Mutations in this gene can prevent the formation of the epidermal permeability barrier and cause an ichthyosiform phenotype. [provided by RefSeq, Sep 2015]
PHENOTYPE: Neonatal homozygous mutant mice exhibit reddened skin that quickly dehydrates and appears scaly. The epidermis is hyperkeratotic, and its permeability barrier function is compromised. Homozygotes die within 24 hours of birth. [provided by MGI curators]
