Darier Disease

Keratosis follicularis


Type of disease: Rare conditions

Darier disease is an inherited skin condition characterized by wart-like blemishes on the body usually located on the scalp, forehead, upper arms, chest, back, knees, elbows, and behind the ear. Other features of Darier disease include nail abnormalities, such as red and white streaks in the nails with an irregular texture, and small pits in the palms of the hands and soles of the feet. The severity of the disease varies over time. A form of Darier disease known as the linear or segmental form is characterized by blemishes on localized areas of the skin.  Darier disease is not an infection and the blemishes are not contagious. Symptoms usually first appear in late childhood or early adulthood. This condition is caused by mutations in the ATP2A2 gene and inherited in an autosomal dominant fashion.Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
