    Mol Genet Genomic Med 2017 11 31;5(6):774-780. Epub 2017 Jul 31.
    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 Caentry 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:

    A microRNA screen reveals that elevated hepatic ectodysplasin A expression contributes to obesity-induced insulin resistance in skeletal muscle.
    Nat Med 2017 Dec 6;23(12):1466-1473. Epub 2017 Nov 6.
    Department of Neuronal Control of Metabolism, Max Planck Institute for Metabolism Research, Cologne, Germany.
    Over 40% of microRNAs (miRNAs) are located in introns of protein-coding genes, and many of these intronic miRNAs are co-regulated with their host genes. In such cases of co-regulation, the products of host genes and their intronic miRNAs can cooperate to coordinately regulate biologically important pathways. Therefore, we screened intronic miRNAs dysregulated in the livers of mouse models of obesity to identify previously uncharacterized protein-coding host genes that may contribute to the pathogenesis of obesity-associated insulin resistance and type 2 diabetes mellitus.

    Clinical factors in prosthodontic treatment of children with genetic defects.
    Adv Clin Exp Med 2017 Sep;26(6):1005-1012
    Department of Dental Prosthetics, Wroclaw Medical University, Poland.
    Background: Prosthodontic treatment of children with genetic disorders is an area that is rarely examined in the current specialist literature. Few prosthodontists will undertake treatment of such patients, who will more often be referred to an orthodontic specialist. After examining the 4 cases of children with genetic disorders described in this paper, it can be concluded that when a prosthodontist includes a few additional procedures in the treatment process, he or she can successfully help such patients.

    Hypomorphic IKBKG mutations in males are typically associated with anhidrotic ectodermal dysplasia with immunodeficiency (EDA-ID). Some mutations cause immunodeficiency without EDA (NEMO-ID). The immunological profile associated with these NEMO-ID variants is not fully documented. Read More

    Novel EDA or EDAR Mutations Identified in Patients with X-Linked Hypohidrotic Ectodermal Dysplasia or Non-Syndromic Tooth Agenesis.

    Both X-linked hypohidrotic ectodermal dysplasia (XLHED) and non-syndromic tooth agenesis (NSTA) result in symptoms of congenital tooth loss. This study investigated genetic causes in two families with XLHED and four families with NSTA. We screened for mutations of WNT10A, EDA, EDAR, EDARADD, PAX9, MSX1, AXIN2, LRP6, and WNT10B through Sanger sequencing. Read More

    Abdominal Imaging Findings in Neurocutaneous Syndromes: Looking Below the Diaphragm.

    1 Department of Radiology, Vancouver General Hospital and University of British Columbia, 899 W 12th Ave, Vancouver, BC V5Z 1M9, Canada.
    Objective: Neurocutaneous syndromes are a heterogeneous group of multisystemic disorders. We review the multimodality imaging findings in the disorders with a propensity for intraabdominal disease. We highlight more recently recognized disease patterns and discuss imaging surveillance optimization. Read More

    Objective: EEC is an acronym for an autosomal dominant syndrome clinically characterized by ectrodactyly (E), ectodermal dysplasia (E) and cleft lip/palate (C). Our aim was to describe a rare case of siblings affected by ectrodactyly, ectodermal dysplasia and cleft lip/palate (EEC) syndrome presenting normal parents.

    Case Description: The patient was the third son of young and healthy parents. Read More

    WNT10A gene is the second molecular candidate in a cohort of young Italian subjects with ectodermal derivative impairment (EDI).

    Ectodermal dysplasias are a group of genetic disorders defined by ectodermal derivative impairment (EDI). To test the impact of the Wnt/beta-catenin pathway in the genetic screening of EDI, we performed a molecular gene study of WNT10A in 60 subjects from a population of 133 young Italian patients referred for the impairment of at least one major ectodermal-derived structure and who had a previous negative molecular screen for ectodysplasin signaling pathway genes ED1, EDAR, and EDARADD. Fourteen WNT10A mutations were identified in 33 subjects (24. Read More

    Laser-Induced Neocollagenesis in Focal Dermal Hypoplasia Associated With Goltz Syndrome in a Girl.
    JAMA Dermatol 2017 Dec;153(12):1292-1297
    Department of Dermatology, Henry Ford Hospital, Detroit, Michigan.
    Importance: Current models of Goltz syndrome cannot estimate the overall neocollagenesis and marked shift in collagen types after ablative fractional laser resurfacing (AFR) within treated areas of focal dermal hypoplasia (FDH).

    Objectives: To clinically improve FDH by using AFR to characterize the specific ratio of collagen types associated with observed clinical changes.

    Design, Setting, And Participants: This case report of a girl with Goltz syndrome used extensive laboratory evaluation and multiple observers blinded to the patient's clinical status. Read More

    Adult Survival in Ellis-van Creveld Syndrome with Common Atrium - A Rare Case Report.

    Consultant Physician, Department of Medicine, Vinaya Hospital, Kundapur, Karnataka, India.
    Ellis-van Creveld syndrome is a rare genetic disorder, characterized by chondral dysplasia, ectodermal dysplasia, polydactyly and congenital heart defects. Patients with this syndrome rarely survive into adulthood. The syndrome has also been rarely reported in the Indian population. Read More

    Gene screening facilitates diagnosis of complicated symptoms: A case report.

    Department of Surgery, Institute of Otolaryngology, Chinese PLA General Hospital, Beijing 100853, P.R. China.
    Gene mutation has an important role in disease pathogenesis; therefore, genetic screening is a useful tool for diagnosis. The present study screened pathogenic genes, ectodysplasin A (EDA) and lamin A/C (LMNA), in a patient with suspected syndromic hearing impairment and various other symptoms including tooth and skin abnormalities. Large‑scale sequencing of 438 deafness‑associated genes and whole‑genome sequencing was also performed. Read More

    Confirmation that RIPK4 mutations cause not only Bartsocas-Papas syndrome but also CHAND syndrome.

    CHAND syndrome is an autosomal recessive disorder characterized by curly hair, ankyloblepharon, and nail dysplasia. Only few patients were reported to date. A homozygous RIPK4 mutation was recently identified by homozygosity mapping and whole exome sequencing in three patients from an expanded consanguineous kindred with a clinical diagnosis of CHAND syndrome.
