    Prenatal Correction of X-Linked Hypohidrotic Ectodermal Dysplasia.
    N Engl J Med 2018 Apr;378(17):1604-1610
    From the Departments of Pediatrics (H.S., I.K., S.W., A.D., M.W., W.R.), Obstetrics and Gynecology (F.F., M.W.B.), and Radiology (O.R.), University of Erlangen-Nürnberg, Erlangen, and Radiology Nienburg, Nienburg/Weser (C.T.) - both in Germany; the Department of Biochemistry, University of Lausanne, Epalinges, Switzerland (S.S.-M., C.K.-Q., M.V., P.S.); and Edimer Pharmaceuticals, Andover, MA (N.K.).
    Genetic deficiency of ectodysplasin A (EDA) causes X-linked hypohidrotic ectodermal dysplasia (XLHED), in which the development of sweat glands is irreversibly impaired, an condition that can lead to life-threatening hyperthermia. We observed normal development of mouse fetuses with Eda mutations after they had been exposed in utero to a recombinant protein that includes the receptor-binding domain of EDA. We administered this protein intraamniotically to two affected human twins at gestational weeks 26 and 31 and to a single affected human fetus at gestational week 26; the infants, born in week 33 (twins) and week 39 (singleton), were able to sweat normally, and XLHED-related illness had not developed by 14 to 22 months of age.

    Institute of Human Genetics, University Hospital Magdeburg, Magdeburg, Germany.
    Background: Johanson-Blizzard syndrome (JBS, MIM #243800) is a very rare autosomal recessive disorder characterized by exocrine pancreatic insufficiency, nasal wing hypoplasia, hypodontia, and other abnormalities. JBS is caused by mutations of the UBR1 gene (MIM *605981), encoding a ubiquitin ligase of the N-end rule pathway.

    Methods: Molecular findings in a total of 65 unrelated patients with a clinical diagnosis of JBS who were previously screened for UBR1 mutations by Sanger sequencing were reviewed and cases lacking a disease-causing UBR1 mutation on either one or both alleles were included in this study.

    Section of Pediatric Dermatology, Department of Pediatrics, Children's Hospital of Philadelphia, Philadelphia, PA, USA.
    Specific clinical features of aplasia cutis congenita may indicate the presence of underlying cranial or cerebrovascular defects, allowing for early recognition and intervention. Most information about aplasia cutis congenita exists as individual case reports, with few large-scale studies. We conducted a 7-year retrospective chart review of 90 cases of aplasia cutis congenita and identified clinical characteristics including morphology, number of lesions, anatomic location, presence of hair collar sign, associated cutaneous features, histology, and imaging results.

    ORAI1 mutations abolishing store-operated Ca entry cause anhidrotic ectodermal dysplasia with immunodeficiency.
    J Allergy Clin Immunol 2017 Nov 16. Epub 2017 Nov 16.
    Department of Pathology, New York University School of Medicine, New York, NY. Electronic address:
    Background: Store-operated Ca entry (SOCE) through Ca release-activated Ca channels is an essential signaling pathway in many cell types.
