Genetic Blistering Diseases

Abstract

The integrity of the skin is maintained by complex networks of structural and non‐structural proteins within the epidermis, epidermal basement membrane zone and upper dermis. Disruption to the function of any one of these integral proteins through inherited gene mutations can make the skin less resilient to trauma and more prone to blister formation. This chapter provides an overview of key proteins involved in skin integrity and outlines the spectrum of blistering diseases linked to abnormalities therein. The text also describes approaches to diagnosis of inherited blistering diseases, as well as innovative therapies which try to reduce blistering and improve skin function.
