Prenatal sonographic diagnosis of Harlequin ichthyosis.

J Clin Ultrasound 2018 Dec 3. Epub 2018 Dec 3.

Department of Obstetrics and Gynaecology, Centro Hospitalar São João, Porto, Portugal.

Harlequin ichthyosis is the most severe form of autosomal recessive congenital ichthyoses. So far, there are only a few reports of prenatal diagnosis in the literature, as prenatal sonographic features are quite subtle. We report a case of prenatal diagnosis of Harlequin ichthyosis on third-trimester sonographic examination in a consanguineous couple with no history of the disease and describe its characteristic sonographic features.

Perspective: Mutations in Recessive Congenital Ichthyoses Illuminate the Origin and Functions of the Corneocyte Lipid Envelope.

J Invest Dermatol 2018 Nov 21. Epub 2018 Nov 21.

Dermatology Service, VA Medical Center, San Francisco and Department of Dermatology, UC San Francisco, San Francisco, CA. Electronic address:

The corneocyte lipid envelope (CLE), a monolayer of ϖ-hydroxyceramides, whose function(s) remain(s) uncertain, is absent in autosomal recessive congenital ichthyoses (ARCI) with mutations in enzymes that regulate epidermal lipid synthesis. Secreted lipids fail to transform into lamellar membranes in certain ARCI epidermis, suggesting the CLE provides a scaffold for the extracellular lamellae. But since cornified envelopes (CEs) are attenuated in these ARCI, the CLE may also provide a scaffold for subjacent CE formation, evidenced by restoration of CEs after CLE 'rescue. Read More

[Sjögren-Larsson syndrome: Pediatric case report].

Arch Argent Pediatr 2018 Dec;116(6):e773-e777

Laboratorio de Bioquímica y Medicina Experimental, Centro Médico Nacional "20 de Noviembre", ISSSTE.

Sjogren-Larsson syndrome is characterized by congenital ichthyosis, mental retardation and spastic diplegia or quadriplegia. The primary defect in this syndrome is mutation of ALDH3A2 gen that codes for the fatty aldehyde dehydrogenase. Deficiency of this enzyme causes an accumulation of fatty alcohols and fatty aldehydes, leading to altered cell-membrane integrity. Read More

Chanarin-Dorfman syndrome.

Turk J Gastroenterol 2018 Nov 16. Epub 2018 Nov 16.

Department of Medical Genetics, Marmara University School of Medicine, İstanbul, Turkey.

Chanarin Dorfman syndrome is a multisystem, very rare, autosomal recessive lipid storage disorder, characterized by the accumulation of lipid vacuoles in neutrophils, and was first described by Dorfman in 1974. Due to a mutation in the ABHD5 gene of the short arm of chromosome 3, lipid is stored in the granulocytes at various sites in the human body, such as the muscle, liver, eye, ear, central nervous system, and bone marrow. Clinically, the disease is presented with ichthyosis, hearing loss, hepatomegaly, splenomegaly, cirrhosis, cataract, keratopathy, myopathy, and mental retardation. Read More

Calcium (Ca) is an essential regulator for a large number of cellular functions in various tissues and organs, and small disturbances of Ca homeostasis can severely compromise normal physiology. Intracellular Ca balance is mainly controlled by the reticular Ca sensor STIM1 and the plasma membrane Ca channel ORAI1 through a mechanism known as store-operated Ca entry (SOCE). Gain-of-function mutations in STIM1 or ORAI1 cause excessive extracellular Ca influx, resulting in tubular aggregate myopathy (TAM) and Stormorken syndrome (STRMK). Read More

Activography reveals aberrant proteolysis in desquamating diseases of differing backgrounds.

Department of Pharmacy, School of Health Sciences, University of Patras, Rion-Patras, 265 04, Greece.

The role of epidermal proteolysis in overdesquamation was revealed in Netherton syndrome, a rare ichthyosis due to genetic deficiency of the LEKTI inhibitor of serine proteases. Recently, we developed activography, a new histochemical method, to spatially localize and semi-quantitatively assess proteolytic activities using activity-based probes. Activography provides specificity and versatility compared to in situ zymography, the only available method to determine enzymatic activities in tissue biopsies. Read More

Patients with Congenital Ichthyosis and TGM1 Mutations Overexpress Other ARCI Genes in the Skin: Part of a Barrier Repair Response?

Exp Dermatol 2018 Oct 29. Epub 2018 Oct 29.

Department of Medical Sciences, Dermatology and Venereology, Uppsala University, SE-751 85, Uppsala, Sweden.

Autosomal recessive congenital ichthyosis (ARCI) is a group of monogenic skin disorders caused by mutations in any of at least 12 different genes, many of which are involved in the epidermal synthesis of ω-O-acylceramides (acylCer). AcylCer are essential precursors of the corneocyte lipid envelope crosslinked by transglutaminase-1 (TGm-1), or a yet unidentified enzyme, for normal skin barrier formation. We hypothesized that inactivating TGM1 mutations will lead to a compensatory overexpression of the transcripts involved in skin barrier repair, including many other ARCI-causing genes. Read More

ABHD5 stimulates PNPLA1-mediated ω--acylceramide biosynthesis essential for a functional skin permeability barrier.

J Lipid Res 2018 Dec 25;59(12):2360-2367. Epub 2018 Oct 25.

Institute of Molecular Biosciences, University of Graz, Graz, Austria

Mutations in the genes coding for patatin-like phospholipase domain-containing 1 (PNPLA1) and α/β-hydrolase domain-containing 5 (ABHD5), also known as comparative gene identification 58, are causative for ichthyosis, a severe skin barrier disorder. Individuals with mutations in either of these genes show a defect in epidermal ω--acylceramide (AcylCer) biosynthesis, suggesting that PNPLA1 and ABHD5 act in the same metabolic pathway. In this report, we identified ABHD5 as a coactivator of PNPLA1 that stimulates the esterification of ω-hydroxy ceramides with linoleic acid for AcylCer biosynthesis. Read More

Trichothiodystrophy (TTD) is a group of predominantly autosomal recessive disorders characterized by sulfur-deficient brittle hair. Clinical features of TTD consist of variable neuroectodermal symptoms including ichthyosis, nail abnormalities, mental retardation, short stature, decreased fertility and proneness to infections. Approximately half of the reported patients with TTD have clinical and cellular photosensitivity associated with mutations in three subunits (ERCC3, ERCC2, GTF2H5) of the basal transcription factor TFHII, which is involved in transcription and nucleotide excision repair.

Loss of GRHL3 leads to TARC/CCL17-mediated keratinocyte proliferation in the epidermis.

Cell Death Dis 2018 Oct 19;9(11):1072. Epub 2018 Oct 19.

Division of Cancer Research, Peter MacCallum Cancer Centre, Grattan Street, Melbourne, VIC, 3000, Australia.

Identifying soluble factors that influence epidermal integrity is critical for the development of preventative and therapeutic strategies for disorders such as ichthyosis, psoriasis, dermatitis and epidermal cancers. The transcription factor Grainyhead-like 3 (GRHL3) is essential for maintaining barrier integrity and preventing development of cutaneous squamous cell carcinoma (SCC); however, how loss of this factor, which in the skin is expressed exclusively within suprabasal epidermal layers triggers proliferation of basal keratinocytes, had thus far remained elusive. Our present study identifies thymus and activation-regulated chemokine (TARC) as a novel soluble chemokine mediator of keratinocyte proliferation following loss of GRHL3. Read More

The role of PNPLA1 in ω-O-acylceramide synthesis and skin barrier function.

Biochim Biophys Acta Mol Cell Biol Lipids 2018 Oct 2. Epub 2018 Oct 2.

Laboratory of Biochemistry, Faculty of Pharmaceutical Sciences, Hokkaido University, Kita 12-jo, Nishi 6-chome, Kita-ku, Sapporo 060-0812, Japan.

The human genome encodes nine enzymes belonging to the patatin-like phospholipase domain-containing lipase (PNPLA)/Ca-independent phospholipase A (iPLA) family. Although most PNPLA/iPLA enzymes are widely distributed and act on phospholipids or neutral lipids as (phospho)lipases to play homeostatic roles in lipid metabolism, the function of PNPLA1 remained a mystery until a few years ago. However, the recent finding that mutations in the human PNPLA1 gene are linked to autosomal recessive congenital ichthyosis (ARCI), as well as evidence obtained from biochemical and gene knockout studies, has shed light on the function of this enzyme in skin-specific sphingolipid metabolism rather than glycerophospholipid metabolism.
