Involvement in diseasei

Epidermodysplasia verruciformis (EV)1 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionRare autosomal recessive genodermatosis associated with a high risk of skin carcinoma that results from an abnormal susceptibility to infection by specific human papillomaviruses. Infection leads to persistent wart-like or macular lesions.
