Abstract

Darier disease (DD) and Hailey–Hailey disease (HHD) are the only known autosomal-dominant Ca2+ ATPase disorders. Epidermal symptoms selectively occur in the affected individuals, the precise reason for which is still not fully understood. Here, we review the clinical, epidermal, and molecular features of the two genodermatoses. It is concluded that epidermal Ca2+ regulation disturbances and epigenetic factors may play an even more prominent role in the pathogenesis of DD and HHD than earlier appreciated.

Abbreviations:

DD, Darier disease; ER, endoplasmic reticulum; HHD, Hailey–Hailey disease; hSPCA, human secretory pathway Ca2+/Mn2+ ATPase; SERCA2, sarco/endoplasmic reticulum Ca2+-transport ATPase isoform 2
