Involvement in diseasei

Palmoplantar keratoderma 1, striate, focal, or diffuse (PPKS1)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA dermatological disorder characterized by thickening of the skin on the palms and soles, and longitudinal hyperkeratotic lesions on the palms, running the length of each finger.
See also OMIM:148700
Erythroderma, congenital, with palmoplantar keratoderma, hypotrichosis, and hyper IgE (EPKHE)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA syndrome characterized by severe dermatitis, multiple allergies and metabolic wasting. Clinical features include erythroderma, yellowish papules and plaques arranged at the periphery of the palms, along the fingers and over weight-bearing areas of the feet, skin erosions and scaling, and hypotrichosis. Additionally, patients manifest severe food allergies, elevated immunoglobulin E (IgE) levels and recurrent infections with marked metabolic wasting.
