Summaries for Peeling Skin Syndrome 2

Genetics Home Reference : 26 Acral peeling skin syndrome is a skin disorder characterized by painless peeling of the top layer of skin. The term "acral" refers to the fact that the skin peeling in this condition is most apparent on the hands and feet. Occasionally, peeling also occurs on the arms and legs. The peeling is usually evident from birth, although the condition can also begin in childhood or later in life. Skin peeling is made worse by exposure to heat, humidity and other forms of moisture, and friction. The underlying skin may be temporarily red and itchy, but it typically heals without scarring. Acral peeling skin syndrome is not associated with any other health problems.

MalaCards based summary : Peeling Skin Syndrome 2, also known as peeling skin syndrome, acral type, is related to peeling skin syndrome and peeling skin syndrome type a. An important gene associated with Peeling Skin Syndrome 2 is TGM5 (Transglutaminase 5), and among its related pathways/superpathways are Developmental Biology and Keratinization. Affiliated tissues include skin, and related phenotypes are ichthyosis and scaling skin

NIH Rare Diseases : 54 Acral peeling skin syndrome is a genetic skin disorder characterized by painless peeling of the top layer of skin. "Acral" refers to the fact that the peeling is most apparent on the hands and feet, although peeling may also occur on the arms and legs. The peeling is usually present from birth, but can appear later in childhood or early adulthood. Acral peeling skin syndrome can be caused by mutations in the TGM5 gene. Mutations in the CSTA gene have also been linked to this condition. It is inherited in anĀ autosomal recessiveĀ pattern. There is no cure for acral peeling skin syndrome. Treatment is aimed at treating the symptoms present in each individual.

OMIM : 58 Peeling skin syndrome (PSS) is an autosomal recessive genodermatosis characterized by the shedding of the outer epidermis. In an acral form of the disorder (PSS2), the dorsa of the hands and feet are predominantly affected, and ultrastructural analysis shows separation at the junction between the granular cells and the stratum corneum in the outer epidermis (summary by Cassidy et al., 2005). For a discussion of genetic heterogeneity of peeling skin syndrome, see PSS1 (270300). (609796)

UniProtKB/Swiss-Prot : 76 Peeling skin syndrome 2: A non-inflammatory and localized form of peeling skin syndrome, a genodermatosis characterized by the continuous shedding of the outer layers of the epidermis. In PSS2 patients, skin peeling is painless and strictly limited to the dorsa of the hands and feet. It is accompanied by painless erythema and spontaneous non-scarring healing. Ultrastructural and histological analysis shows a level of blistering high in the epidermis at the stratum granulosum-stratum corneum junction.
