The epidermal lipoxygenases 12R-LOX and eLOX3 act in sequence to convert arachidonic acid via 12(R)-HPETE to 12(R)-HETE and the corresponding epoxyalcohol, 8(R)-hydroxy-11(R),12(R)-epoxyeicosatrienoic acid. The epidermal lipoxygenases 12R-LOX and eLOX3 are the gene products of ALOX12B and ALOXE3. Mutations in ALOXE3 or ALOX12B have been found in families with autosomal-recessive congenital ichthyosis (ARCI). ARCI is a clinically and genetically heterogeneous group of severe hereditary keratinization disorders characterized by intense scaling of the whole integument, and differences in color and shape, often associated with erythema. Mutations in ALOXE3 and ALOX12B on chromosome 17p13, which code for two different epidermal lipoxygenases, were found in patients with ichthyosiform erythroderma. Genetic studies indicated that 12R-lipoxygenase (12R-LOX) or epidermal lipoxygenase-3 (eLOX3) was mutated in six families affected by non-bullous congenital ichthyosiform erythroderma (NCIE), one of the main clinical forms of ichthyosis.
