Usefulness of the skin biopsy as a tool in the diagnosis of silvery hair syndrome.

Pediatr Dermatol 2018 Nov 18;35(6):780-783. Epub 2018 Oct 18.

Department of Dermatology, National Institute of Pediatrics, Mexico City, Mexico.

Background/objectives: Silvery hair syndrome is a rare, autosomal-recessive entity characterized by silvery gray hair, eyebrows, and eyelashes and may be associated or not with immunologic or neurologic alterations. Two main types have been recognized: Chediak-Higashi syndrome and Griscelli syndrome. Hair shaft examination under light microscopy has been a useful tool to differentiate Chediak-Higashi syndrome from Griscelli syndrome, although distribution of melanin varies according to hair color related to ethnicity.

[Rare diseases recognizable from blood smears].

Internist (Berl) 2018 Oct;59(10):1106-1113

Klinik für Hämatologie, Onkologie und Immunologie, Universitätsklinikum Gießen und Marburg, Standort Marburg, Philipps-Universität Marburg, Baldingerstr., 35043, Marburg, Deutschland.

The examination of peripheral blood smears is not only essential for the differential diagnostics of hematological diseases but can also provide important indications for general internal diseases, infections, hereditary diseases and poisoning. By the systematic analysis of a blood smear for alterations to thrombocytes, erythrocytes and leukocytes, a blood smear investigation can make a decisive contribution to the formulation of a diagnosis. In this way evidence of rare diseases can also be gained when taking the corresponding clinical findings into consideration. Read More

NBEAL2 mutations and bleeding in patients with gray platelet syndrome.

Platelets 2018 Sep 5;29(6):632-635. Epub 2018 Jun 5.

a Cell Biology Program , Research Institute, Hospital for Sick Children , Toronto , ON , Canada.

Homozygosity/compound heterozygosity for loss of function mutations in neurobeachin-like 2 (NBEAL2) is causative for Gray platelet syndrome (GPS; MIM #139090), characterized by thrombocytopenia and large platelets lacking α-granules and cargo. Most GPS-associated NBEAL2 mutations generate nonsense codons; frameshifts causing premature translation termination and/or changes in mRNA splicing have also been observed. Data regarding NBEAL2 protein expression in GPS patients is limited. Read More

Periodontitis in Chédiak-Higashi Syndrome: An Altered Immunoinflammatory Response.

JDR Clin Trans Res 2018 Jan 3;3(1):35-46. Epub 2017 Aug 3.

Department of Pediatric Dentistry, State University of Campinas, Piracicaba Dental School, Piracicaba, SP, Brazil.

Chédiak-Higashi syndrome (CHS), a rare autosomal recessive disorder caused by mutations in the lysosomal trafficking regulator gene (LYST), is associated with aggressive periodontitis. It is suggested that LYST mutations affect the toll-like receptor (TLR)-mediated immunoinflammatory response, leading to frequent infections. This study sought to determine the periodontal status of patients with classic (severe) and atypical (milder) forms of CHS and the immunoregulatory functions of gingival fibroblasts in CHS patients.

Receptor Cell Biology Section, Laboratory of Immunogenetics, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Rockville, MD. Electronic address:

Background: Chediak-Higashi syndrome (CHS) is a rare disorder caused by biallelic mutations in the lysosomal trafficking regulator gene (LYST), resulting in formation of giant lysosomes or lysosome-related organelles in several cell types. The disease is characterized by immunodeficiency and a fatal hemophagocytic lymphohistiocytosis caused by impaired function of cytotoxic lymphocytes, including natural killer (NK) cells.

Objective: We sought to determine the underlying biochemical cause of the impaired cytotoxicity of NK cells in patients with CHS. Read More

Hermansky-Pudlak syndrome: Report of two patients with updated genetic classification and management recommendations.

Pediatr Dermatol 2017 Nov 16;34(6):638-646. Epub 2017 Oct 16.

Ann & Robert H. Lurie Children's Hospital of Chicago, Chicago, IL, USA.

Hermansky-Pudlak syndrome (HPS) is a rare autosomal recessive disorder caused by mutations in one of nine genes involved in the packaging and formation of specialized lysosomes, including melanosomes and platelet-dense granules. The cardinal features are pigmentary dilution, bleeding diathesis, and accumulation of ceroid-like material in reticuloendothelial cells. Pulmonary fibrosis induced by tissue damage is seen in the most severe forms, and one subtype is characterized by immunodeficiency. Read More

The Neurobeachin-like 2 Protein Regulates Mast Cell Homeostasis.

J Immunol 2017 10 8;199(8):2948-2957. Epub 2017 Sep 8.

Institute of Immunology, Jena University Hospital, 07743 Jena, Germany.

The neurobeachin-like 2 protein (Nbeal2) belongs to the family of beige and Chediak-Higashi (BEACH) domain proteins. Loss-of-function mutations in the human gene or Nbeal2 deficiency in mice cause gray platelet syndrome, a bleeding disorder characterized by macrothrombocytopenia, splenomegaly, and paucity of α-granules in megakaryocytes and platelets. We found that in mast cells, Nbeal2 regulates the activation of the Shp1-STAT5 signaling axis and the composition of the c-Kit/STAT signalosome. Read More

CHS is a rare immunodeficiency syndrome with defects in the functions of cytotoxic cells and neutrophils. Approximately 85% of patients with CHS undergo an AP within the first decade, which is similar to FHLH. Chemotherapy could induce transient remission, but only allogeneic HCT could correct the underlying genetic defect and prevent relapse. Read More

Autophagy-dependent clearance of ubiquitinated and aggregated proteins is critical to protein quality control, but the underlying mechanisms are not well understood. Here, we report the essential role of the BEACH (beige and Chediak-Higashi) and WD40 repeat-containing protein WDR81 in eliminating ubiquitinated proteins through autophagy. WDR81 associates with ubiquitin (Ub)-positive protein foci, and its loss causes accumulation of Ub proteins and the autophagy cargo receptor p62. Read More

Subcellular compartmentalization of receptor signaling is an emerging principle in innate immunity. However, the functional integration of receptor signaling pathways into membrane trafficking routes and its physiological relevance for immune responses is still largely unclear. In this study, using Lyst-mutant beige mice, we show that lysosomal trafficking regulator Lyst links endolysosomal organization to the selective control of toll-like receptor 3 (TLR3)- and TLR4-mediated proinflammatory responses.

NK cell effector functions in a Chédiak-Higashi patient undergoing cord blood transplantation: Effects of in vitro treatment with IL-2.

Department of Molecular Medicine, Istituto Pasteur-Fondazione Cenci Bolognetti, "Sapienza" University of Rome, Italy.

NK cell cytotoxicity in Chédiak-Higashi syndrome (CHS) is strongly impaired as lytic granules are not released upon NK-target cell contact, contributing to several defects typical of this severe immunodeficiency. Correction of NK cell defects in CHS should improve the outcome of hematopoietic stem-cell transplantation, proposed as therapy. We investigated NK cell functions in a CHS patient before and after cord-blood transplantation, and the ability of in vitro IL-2 treatment to restore them. Read More

Department of Dermatology, Hospital Clínic, University of Barcelona, Spain.

Silvery hair is a characteristic finding of 3 rare autosomal recessive disorders: Chédiak-Higashi syndrome (CHS), Elejalde syndrome (ES), and Griscelli syndrome (GS). We report the case of a 2-month-old male infant with transient silvery hair and generalized hypopigmentation of the skin and eyes who did not have one of these classic causative disorders. The patient was delivered at 35 weeks' gestation with congenital hydrops fetalis associated with a chromosomal abnormality (46,XY,add[2],[p23]), hypothyroidism, hypoproteinemia, and hypogammaglobulinemia.
