KRT5

The protein encoded by this gene is a member of the keratin gene family. The type II cytokeratins consist of basic or neutral proteins which are arranged in pairs of heterotypic keratin chains coexpressed during differentiation of simple and stratified epithelial tissues. This type II cytokeratin is specifically expressed in the basal layer of the epidermis with family member KRT14. Mutations in these genes have been associated with a complex of diseases termed epidermolysis bullosa simplex. The type II cytokeratins are clustered in a region of chromosome 12q12-q13.

Involvement in disease

Epidermolysis bullosa simplex, autosomal recessive 1 (EBSB1):
A form of epidermolysis bullosa, a genodermatosis characterized by recurrent blistering and cleavage within basal keratinocytes, fragility of the skin and mucosal epithelia, and erosions caused by minor mechanical trauma.
Epidermolysis bullosa simplex, Dowling-Meara type (DM-EBS):
A severe form of intraepidermal epidermolysis bullosa characterized by generalized herpetiform blistering, milia formation, dystrophic nails, and mucous membrane involvement.
Epidermolysis bullosa simplex, with migratory circinate erythema (EBSMCE):
A form of intraepidermal epidermolysis bullosa characterized by unusual migratory circinate erythema. Skin lesions appear from birth primarily on the hands, feet, and legs but spare nails, ocular epithelia and mucosae. Lesions heal with brown pigmentation but no scarring. Electron microscopy findings are distinct from those seen in the DM-EBS, with no evidence of tonofilament clumping.
Epidermolysis bullosa simplex, Weber-Cockayne type (WC-EBS):
A form of intraepidermal epidermolysis bullosa characterized by blistering limited to palmar and plantar areas of the skin.
Epidermolysis bullosa simplex, Koebner type (K-EBS):
A form of intraepidermal epidermolysis bullosa characterized by generalized skin blistering. The phenotype is not fundamentally distinct from the Dowling-Meara type, although it is less severe.
Epidermolysis bullosa simplex, with mottled pigmentation (MP-EBS):
A form of intraepidermal epidermolysis bullosa characterized by blistering at acral sites and 'mottled' pigmentation of the trunk and proximal extremities with hyper- and hypopigmentation macules.
Dowling-Degos disease 1 (DDD1):
An autosomal dominant genodermatosis. Affected individuals develop a postpubertal reticulate hyperpigmentation that is progressive and disfiguring, and small hyperkeratotic dark brown papules that affect mainly the flexures and great skin folds. Patients usually show no abnormalities of the hair or nails.
