    All-Atom Molecular Dynamics Comparison of Disease-Associated Zinc Fingers.
    J Biomol Struct Dyn 2017 Aug 17:1-30. Epub 2017 Aug 17.
    a Department of Physics , Wake Forest University , Winston-Salem , NC.
    An important regulatory domain of NEMO is a ubiquitin-binding zinc finger, with a tetrahedral CYS3HIS1 zinc-coordinating binding site. Two variations of NEMO's zinc finger are implicated in various disease states including ectodermal dysplasia and adult-onset glaucoma. To discern structural and dynamical differences between these disease states, we present results of 48-$\mu s$ of molecular dynamics simulations for three zinc finger systems each in two states, with and without zinc-bound and correspondingly appropriate cysteine thiol/thiolate configurations.

    The Impact of the Eda Pathway on Tooth Root Development.
    J Dent Res 2017 Aug 1:22034517725692. Epub 2017 Aug 1.
    1 Department of Craniofacial Development and Stem Cell Biology, King's College London, London, UK.
    The Eda pathway ( Eda, Edar, Edaradd) plays an important role in tooth development, determining tooth number, crown shape, and enamel formation. Here we show that the Eda pathway also plays a key role in root development. Edar (the receptor) is expressed in Hertwig's epithelial root sheath (HERS) during root development, with mutant mice showing a high incidence of taurodontism: large pulp chambers lacking or showing delayed bifurcation or trifurcation of the roots.

    Ectodysplasin A regulates epithelial barrier function through sonic hedgehog signalling pathway.
    J Cell Mol Med 2017 Aug 7. Epub 2017 Aug 7.
    Eye Institute of Xiamen University, Xiamen, Fujian, China.
    Ectodysplasin A (Eda), a member of the tumour necrosis factor superfamily, plays an important role in ectodermal organ development. An EDA mutation underlies the most common of ectodermal dysplasias, that is X-linked hypohidrotic ectodermal dysplasia (XLHED) in humans. Even though it lacks a developmental function, the role of Eda during the postnatal stage remains elusive. Read More

    Novel nonsense gain-of-function NFKB2 mutations associated with a combined immunodeficiency phenotype.
    Blood 2017 08 4. Epub 2017 Aug 4.
    Immunology Service, Department of Laboratory Medicine, Clinical Center, National Institutes of Health, Bethesda, MD, United States;
    NF-κB signaling through its NFKB1-dependant canonical and NFKB2-dependant non-canonical pathways play distinctive roles in a diverse range of immune processes. Recently, mutations in these two genes have been associated with common variable immunodeficiency (CVID). While studying patients with genetically-uncharacterized primary immunodeficiencies we detected two novel nonsense gain-of-function (GOF) NFKB2 mutations in three patients from two families (E418X and R635X), and a novel missense change in another patient (S866R).

    J Dent Res 2017 Jul 1:22034517719872. Epub 2017 Jul 1.
    1 Section of Orthodontics and Dentofacial Orthopedics, Division of Oral Health, Growth, and Development, Faculty of Dental Science, Kyushu University, Fukuoka, Japan.
    Loss-of-function mutations in the Ca(2+) release-activated Ca(2+) channel genes ORAI1 and STIM1 abolish store-operated Ca(2+) entry (SOCE) and result in ectodermal dysplasia with amelogenesis imperfecta. However, because of the limited availability of patient tissue, analyses of enamel mineralization or possible changes in ameloblast function or morphology have not been possible. Here, we generated mice with ectodermal tissue-specific deletion of Stim1 ( Stim1 cKO [conditional knockout]), Stim2 ( Stim2 cKO), and Stim1 and Stim2 ( Stim1/2 cKO) and analyzed their enamel phenotypes as compared with those of control ( Stim1/2(fl/fl)) animals.

    The dental phenotype of hairless dogs with FOXI3 haploinsufficiency.
    Sci Rep 2017 Jul 14;7(1):5459. Epub 2017 Jul 14.
    Institut für Spezielle Zoologie und Evolutionsbiologie mit Phyletischem Museum, Friedrich-Schiller-Universität, Erbertstrasse 1, 07743, Jena, Germany.
    Hairless dog breeds show a form of ectodermal dysplasia characterised by a lack of hair and abnormal tooth morphology. This has been attributed to a semi-dominant 7-base-pair duplication in the first exon of the forkhead box I3 gene (FOXI3) shared by all three breeds. Here, we identified this FOXI3 variant in a historical museum sample of pedigreed hairless dog skulls by using ancient DNA extraction and present the associated dental phenotype. Read More

    Hematopoietic stem cell transplantation in 29 patients hemizygous for hypomorphic IKBKG / NEMO mutations.
    Blood 2017 Jul 5. Epub 2017 Jul 5.
    Study Center for Immunodeficiencies, Assistance Publique-Hopitaux de Paris (APHP), Necker Hospital for Sick Children, Paris, France;
    X-linked recessive ectodermal dysplasia (EDA) with immunodeficiency (XR-EDA-ID) is a rare primary immunodeficiency (PID) caused by hypomorphic mutations of the IKBKG gene encoding the NEMO protein. This condition displays enormous allelic, immunological, and clinical heterogeneity, and therapeutic decisions are difficult because NEMO operates in both hematopoietic and non-hematopoietic cells. Hematopoietic stem cell transplantation (HSCT) is potentially life-saving, but the small number of case reports available suggests that it has been reserved for only the most severe cases. Read More

    From the Eye Institute of Xiamen University, Xiamen, Fujian 361102,
    The EDA gene encodes ectodysplasin A (Eda), which if mutated causes X-linked hypohidrotic ectodermal dysplasia (XLHED) disease in humans. Ocular surface changes occur in XLHED patients whereas its underlying mechanism remains elusive. In this study, we found Eda was highly expressed in meibomian glands, and it was detected in human tears but not serum. Read More

    Mechanisms of genotype-phenotype correlation in autosomal dominant anhidrotic ectodermal dysplasia with immune deficiency.
    J Allergy Clin Immunol 2017 Jun 17. Epub 2017 Jun 17.
    Division of Immunology, Boston Children's Hospital, Harvard Medical School, Boston, Mass. Electronic address:
    Background: Autosomal dominant anhidrotic ectodermal dysplasia with immune deficiency (AD EDA-ID) is caused by heterozygous point mutations at or close to serine 32 and serine 36 or N-terminal truncations in IκBα that impair its phosphorylation and degradation and thus activation of the canonical nuclear factor κ light chain enhancer of activated B cells (NF-κB) pathway. The outcome of hematopoietic stem cell transplantation is poor in patients with AD EDA-ID despite achievement of chimerism. Mice heterozygous for the serine 32I mutation in IκBα have impaired noncanonical NF-κB activity and defective lymphorganogenesis. Read More

    Human IκBα Gain of Function: a Severe and Syndromic Immunodeficiency.
    J Clin Immunol 2017 Jul 9;37(5):397-412. Epub 2017 Jun 9.
    St. Giles Laboratory of Human Genetics of Infectious Diseases, Rockefeller Branch, Rockefeller University, New York, USA.
    Germline heterozygous gain-of-function (GOF) mutations of NFKBIA, encoding IκBα, cause an autosomal dominant (AD) form of anhidrotic ectodermal dysplasia with immunodeficiency (EDA-ID). Fourteen unrelated patients have been reported since the identification of the first case in 2003. All mutations enhanced the inhibitory activity of IκBα, by preventing its phosphorylation on serine 32 or 36 and its subsequent degradation. Read More

    WNT10A mutation causes ectodermal dysplasia by impairing progenitor cell proliferation and KLF4-mediated differentiation.
    Nat Commun 2017 Jun 7;8:15397. Epub 2017 Jun 7.
    Department of Dermatology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania 19104, USA.
    Human WNT10A mutations are associated with developmental tooth abnormalities and adolescent onset of a broad range of ectodermal defects. Here we show that β-catenin pathway activity and adult epithelial progenitor proliferation are reduced in the absence of WNT10A, and identify Wnt-active self-renewing stem cells in affected tissues including hair follicles, sebaceous glands, taste buds, nails and sweat ducts. Human and mouse WNT10A mutant palmoplantar and tongue epithelia also display specific differentiation defects that are mimicked by loss of the transcription factor KLF4. Read More

    Hypohidrotic Ectodermal Dysplasia: Breastfeeding Complications Due to Impaired Breast Development.

    EOGT and O-GlcNAc on secreted and membrane proteins.
    Biochem Soc Trans 2017 Apr;45(2):401-408
    Department of Cell Biology, Albert Einstein College of Medicine, New York, NY 10461, U.S.A.
    Here, we describe a recently discovered O-GlcNAc transferase termed EOGT for EGF domain-specific O-GlcNAc transferase. EOGT transfers GlcNAc (N-acetylglucosamine) to Ser or Thr in secreted and membrane proteins that contain one or more epidermal growth factor-like repeats with a specific consensus sequence. Thus, EOGT is distinct from OGT, the O-GlcNAc transferase, that transfers GlcNAc to Ser/Thr in proteins of the cytoplasm or nucleus. Read More

    Am J Med Genet A 2017 May 28;173(5):1186-1189. Epub 2017 Mar 28.
    Department of Medical Genetics, Skeletal Dysplasia Group, University of Campinas (UNICAMP), Campinas, São Paulo, Brazil.
    Since most short-rib polydactyly phenotypes are due to genes involved with biogenesis and maintenance of the primary cilium, this group of skeletal dysplasias was recently designated as ciliopathies with major skeletal involvement. Beemer-Langer syndrome or short-rib polydactyly type IV, was first described in 1983, and has, thus far, remained without a defined molecular basis. The most recent classification of the skeletal dysplasias referred to this phenotype as an as-yet unproven ciliopathy. Read More
