Novel insights into PORCN mutations, associated phenotypes and pathophysiological aspects.

Orphanet J Rare Dis 2022 01 31;17(1):29. Epub 2022 Jan 31.

Izmir Biomedicine and Genome Center, Dokuz Eylul University Health Campus, Izmir, Turkey.

Background: Goltz syndrome (GS) is a X-linked disorder defined by defects of mesodermal- and ectodermal-derived structures and caused by PORCN mutations. Features include striated skin-pigmentation, ocular and skeletal malformations and supernumerary or hypoplastic nipples. Generally, GS is associated with in utero lethality in males and most of the reported male patients show mosaicism (only three non-mosaic surviving males have been described so far). Read More

Structural model of human PORCN illuminates disease-associated variants and drug-binding sites.

J Cell Sci 2021 12 20;134(24). Epub 2021 Dec 20.

Programme in Cancer and Stem Cell Biology, Duke-NUS Medical School, 169857, Singapore.

Wnt signaling is essential for normal development and is a therapeutic target in cancer. The enzyme PORCN, or porcupine, is a membrane-bound O-acyltransferase (MBOAT) that is required for the post-translational modification of all Wnts, adding an essential mono-unsaturated palmitoleic acid to a serine on the tip of Wnt hairpin 2. Inherited mutations in PORCN cause focal dermal hypoplasia, and therapeutic inhibition of PORCN slows the growth of Wnt-dependent cancers. Read More

Authors:
Albert C Yan

Curr Opin Pediatr 2021 12;33(6):704-708

Section of Dermatology, Children's Hospital of Philadelphia, Departments of Pediatrics and Dermatology, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, Pennsylvania, USA.

Purpose Of Review: Acquired postinflammatory lentiginosis is a phenomenon that has been previously termed 'induction of lentiginosis in assorted dermatoses' or the ILIAD phenomenon.

Recent Findings: Although some cases have been described as arising exclusively in those who applied topical calcineurin inhibitors (TCIs), other patients have presented with similar findings in other nonatopic disorders (contact dermatitis, psoriasis, lichen planus, focal dermal hypoplasia), and without antecedent use of TCIs.

Summary: Inflammatory skin disorders can produce localized areas of cutaneous lentiginosis, particularly as the inflammation retreats in response to treatment. Read More

Determination of the membrane topology of PORCN, an O-acyl transferase that modifies Wnt signalling proteins.

Open Biol 2021 06 30;11(6):200400. Epub 2021 Jun 30.

Department of Biology, San Francisco State University, 1600 Holloway Avenue, San Francisco, CA 94132, USA.

Wnt gradients elicit distinct cellular responses, such as proliferation, specification, differentiation and survival in a dose-dependent manner. Porcupine (PORCN), a membrane-bound O-acyl transferase (MBOAT) that resides in the endoplasmic reticulum, catalyses the addition of monounsaturated palmitate to Wnt proteins and is required for Wnt gradient formation and signalling. In humans, PORCN mutations are causal for focal dermal hypoplasia (FDH), an X-linked dominant syndrome characterized by defects in mesodermal and endodermal tissues. Read More

Drs. Stefanis, Arenbergerova, and Arenberger are with the Department of Dermatology and Venereology, Faculty Hospital Kralovske Vinohrady and Third Medical Faculty of Charles University in Prague, the Czech Republic.

Adipose cells organized in small clusters under the reticular dermis closely interact with hair follicular cells and regulate the hair cycle. Intradermal adipocyte progenitor cells are activated toward the end of the telogen phase to proliferate and differentiate into mature adipocytes. These cells, surrounding the hair follicles, secrete signaling molecules that control the progression of the hair cycle. Read More

Band-like Lipomatous Metaplasia of the Superficial Dermis and Nonseptate Subcutaneous Tissue: A Rare Histopathological Phenomenon With Ultrasonographic Correlation.

Am J Dermatopathol 2020 Jul;42(7):526-529

Pathology Department, Hospital Universitari General de Catalunya (HUGC), Sant Cugat del Vallès, Spain; and.

Lipomatous metaplasia of the upper dermis is a rare phenomenon scarcely described in the literature which has always been identified in the context of inflammatory or neoplastic processes. Microscopically, it should be distinguished from pseudolipomatosis cutis, dermal lipoma, nevus lipomatosus, and focal dermal hypoplasia (Goltz syndrome). This is the first report of the histologic and ultrasound evaluation of a patient with extensive involvement and the description of the coincidental finding of an anomalous nonseptate subcutaneous tissue.
