What causes Darier disease?

Darier disease is caused by mutations in the ATP2A2 gene. The linear form of Darier disease is caused by acquired somatic mutations that occur within the ATP2A2 gene; these mutations usually occur by chance and are not inherited from an affected parent. Various environmental factors may also contribute to flare-ups in affected individuals, especially during the summertime when there is increased exposure to heat and humidity. Flare-ups may also be caused by UV light exposure, friction, minor injuries, and certain medications.[1]
