There are disorders of: pigmentation (e.g., albinism), cornification (e.g., the ichthyoses and Darier disease), vascularization (e.g., Sturge-Weber syndrome), connective tissue (e.g., Ehlers-Danlos syndrome), metabolism (e.g., phenylketonuria), immune system (e.g., Wiskott-Aldrich syndrome), and DNA repair (e.g., xeroderma pigmentosa). Some textbooks are dedicated to the topic of genodermatoses alone.1 This chapter introduces the topic and illustrates several genodermatoses. We will focus our discussion on Darier disease and pachyonychia congenita as an introduction to the genodermatoses.
