| Description |
Palmoplantar keratoderma Nagashima type (PPKN) is an autosomal recessive nonsyndromic diffuse palmoplantar keratosis characterized by diffuse hyperkeratosis with redness, expanding on to the dorsal surfaces of the palms and feet and the Achilles tendon area. Its clinical manifestations are similar to but milder than those of mal de Meleda. It has been reported that mutations in SERPINB7, encoding a member of the serine protease inhibitor, cause PPKN.
