Genetic, clinical, and laboratory markers for DOCK8 immunodeficiency syndrome.

DOCK8 immunodeficiency syndrome (DIDS) is a combined immunodeficiency characterized by recurrent viral infections, severe atopy, and early onset malignancy. Genetic studies revealed large, unique deletions in patients from different families and ethnic backgrounds. Clinical markers of DIDS include atopic dermatitis, allergies, cutaneous viral infections, recurrent respiratory tract infections, and malignancy. Immune assessments showed T cell lymphopenia, hyper-IgE, hypo-IgM, and eosinophilia. The impaired lymphocyte functions in DIDS patients appear central for disease pathogenesis.

Atopic dermatitis, STAT3- and DOCK8-hyper-IgE syndromes differ in IgE-based sensitization pattern.

Allergy 2014 Jul;69(7):943-53

University Children's Hospital at Dr. von Haunersches Kinderspital, Ludwig Maximilian University, Munich, Germany; Dermatology and Allergy, Ludwig Maximilian University, Munich, Germany.

Background: Increased serum IgE levels are characteristic but not specific for allergic diseases. Particularly, severe atopic dermatitis (AD) overlaps with hyper-IgE syndromes (HIES) regarding eczema, eosinophilia, and increased serum IgE levels. HIES are primary immunodeficiencies due to monogenetic defects such as in the genes DOCK8 and STAT3. Read More

[Severe atopy and allergy--rare hyper-IgE syndrome caused by the DOCK8 mutation as underlying condition].

Duodecim 2015 ;131(6):541-4

The DOCK8 hyperimmunoglobulin E syndrome is an autosomal recessive primary combined immunological deficiency. Severe atopic eczema having its onset in infancy, food allergies, chronic viral infections of the skin, and recurrent pneumonias are central symptoms. Serum IgE level is high and eosinophilia is found in the blood. Read More

The extended clinical phenotype of 64 patients with dedicator of cytokinesis 8 deficiency.

J Allergy Clin Immunol 2015 Aug 25;136(2):402-12. Epub 2015 Feb 25.

Department of Immunology and Molecular Pathology, Royal Free Hospital and University College London, London, United Kingdom; Center for Chronic Immunodeficiency (CCI), University Medical Center Freiburg, Freiburg, Germany. Electronic address:

Background: Mutations in dedicator of cytokinesis 8 (DOCK8) cause a combined immunodeficiency (CID) also classified as autosomal recessive (AR) hyper-IgE syndrome (HIES). Recognizing patients with CID/HIES is of clinical importance because of the difference in prognosis and management.

Objectives: We sought to define the clinical features that distinguish DOCK8 deficiency from other forms of HIES and CIDs, study the mutational spectrum of DOCK8 deficiency, and report on the frequency of specific clinical findings. Read More

DOCK8 deficiency.

Ann N Y Acad Sci 2011 Dec;1246:26-33

Laboratory of Host Defenses, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, Maryland 20892-1546, USA.

The discovery that loss-of-function mutations in the gene DOCK8 are responsible for most forms of autosomal recessive hyper-IgE syndrome and some forms of combined immunodeficiency without elevated serum IgE has led to studies into the immunopathogenesis of this disease. In this review, we relate the clinical features of this disease to studies using patients' cells and a mouse model of Dock8 deficiency, which have revealed how DOCK8 regulates T and B cell numbers and functions. The results of these studies help to explain how the absence of DOCK8 contributes to patients' susceptibility to viral, fungal, and bacterial infections. Read More
