Abstract     Darier disease (DD) is caused by mutations of the ATP2A2 gene, which encodes the sarco/endoplasmic reticulum Ca(2+)-ATPase isoform 2 (SERCA2). The mutations affect protein expression, degradation and activity. We report a patient with severe sporadic DD, who did not respond adequately to repeated courses of orally administered acitretin and isotretinoin. He was found to harbor the missense P160L mutation of the ATP2A2 gene in a heterozygous state in the A domain of SERCA2 and polymorphism in intron 18 (2741 + 54 G --> A). The A domain plays a key role in translocation of Ca(2+) from cytoplasm to endoplasmic reticulum lumen, thus establishing a low intracellular Ca(2+) concentration.
