Erythrokeratoderma variabilis is a rare genodermatosis characterized by both transient, demarcated erythema and persistent hyperkeratosis. Lesions usually appear within the first year of life but may arise later in childhood. Diffuse palmoplantar keratoderma is common. Erythrokeratodermia variabilis et progressiva (EKVP) is caused by mutations in GJB3, GJB4, and GJA1, the genes encoding for connexin channels proteins in the epidermis.
