    Am J Dermatopathol 2017 May;39(5):370-373
    *Divisions of Dermatopathology and Dermatology, Department of Pathology, Albany Medical College, Albany, NY; †Division of Dermatology, Upper Hudson Valley Dermatology, Castleton, NY; and ‡Departments of Dermatology, Microbiology/Medical Genetics, and Internal Medicine, University of Texas Health Science Center, Houston, TX.
    The co-existence of Darier disease (DD) and acrokeratosis verruciformis of Hopf (AKV) has been noted for decades and the relationship between the 2 entities remains controversial. Although, it has been shown that both diseases are associated with mutations in ATPA2 gene, it is yet to be determined if they are the same disease, or separate but allelic, or interlinked in some other fashion. Herein, the authors report the case of a 13-year-old girl presenting with shiny flat-topped verruca plana-like papules, on the dorsal hands and feet and red-brown crusted papules on her forehead and along the sides of her neck.

    ER-to-Golgi blockade of nascent desmosomal cadherins in SERCA2-inhibited keratinocytes: Implications for Darier's disease.
    Traffic 2017 Apr 28;18(4):232-241. Epub 2017 Feb 28.
    Department of Dermatology, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina.
    Darier's disease (DD) is an autosomal dominantly inherited skin disorder caused by mutations in sarco/endoplasmic reticulum Ca(2+) -ATPase 2 (SERCA2), a Ca(2+) pump that transports Ca(2+) from the cytosol to the endoplasmic reticulum (ER). Loss of desmosomes and keratinocyte cohesion is a characteristic feature of DD. Desmosomal cadherins (DC) are Ca(2+) -dependent transmembrane adhesion proteins of desmosomes, which are mislocalized in the lesional but not perilesional skin of DD. Read More

    The parathyroid hormone family member TIP39 interacts with sarco/endoplasmic reticulum Ca(2+) - ATPase activity by influencing calcium homoeostasis.
    Exp Dermatol 2017 Jan 17. Epub 2017 Jan 17.
    Department of Dermatology, University of California San Diego, La Jolla, CA, USA.
    Darier disease (DD) is a genetic skin disease that is associated with mutations in the ATP2A2 gene encoding the type 2 sarco/endoplasmic reticulum (ER) Ca(2+) - ATPase (SERCA2). Mutations of this gene result in alterations of calcium homoeostasis, abnormal epidermal adhesion and dyskeratosis. Silencing of ATP2A2 in monolayer cell culture of keratinocytes reduces desmoplakin expression at the borders of cells and impacts cell adhesion. Read More

    Team for Advanced Development and Evaluation of Human Disease Models, Riken BioResource Center (BRC), Tsukuba, Ibaraki, Japan; Department of Cell Biology, Cancer Institute, The Japanese Foundation for Cancer Research, Tokyo, Japan. Electronic address:
    Dominant mutations in the Serca2 gene, which encodes sarco(endo)plasmic reticulum calcium-ATPase, predispose mice to gastrointestinal epithelial carcinoma [1-4] and humans to Darier disease (DD) [14-17]. In this study, we generated mice harboring N-ethyl-N-nitrosourea (ENU)-induced allelic mutations in Serca2: three missense mutations and one nonsense mutation. Mice harboring these Serca2 mutations developed tumors that were categorized as either early onset squamous cell tumors (SCT), with development similar to null-type knockout mice [2,4] (aggressive form; M682, M814), or late onset tumors (mild form; M1049, M1162).
