Some primary immune deficiencies include ataxia-telangiectasia (A-T), autosomal recessive agammaglobulinemia (ARA), common variable immunodeficiency (CVID), hyper-IgM syndromes, IgG subclass deficiency, isolated non-IgG immunoglobulin deficiencies, severe combined immunodeficiency (SCID), specific antibody deficiency (SAD), Wiskott-Aldrich syndrome, or X-linked agammaglobulinemia. (wikipedia.org)
A diagnosis of common variable immunodeficiency (CVID) is based on defective functional antibody formation, usually accompanied by decreased (not absent) serum immunoglobulin (Ig)G and IgA levels, generally (not invariably) decreased serum IgM, and exclusion of other known causes of antibody deficiency. (medscape.com)
The remaining type is early onset non-Bruton agammaglobulinemia, with low or absent serum immunoglobulin (Ig). (medscape.com)
Most cases are agammaglobulinemia with autosomal recessive/dominant heritage and represent a very heterogeneous group, including immunoglobulin (Ig) deficiency with increased immunoglobulin M (hyper-IgM syndrome), which is also discussed separately (see X-linked Immunodeficiency With Hyper IgM). (medscape.com)
B-cell deficiency agammaglobulinemia is a form of total immunoglobulin deficiency, which is second most common after total variable immune deficiency. (stop-seizures-meds.com)
Bruton Agammaglobulinemia5
X-linked agammaglobulinemia (XLA), or Bruton agammaglobulinemia, is an inherited immunodeficiency disease caused by mutations in the gene coding for Bruton tyrosine kinase (BTK). (medscape.com)
The diagnosis is confirmed by abnormally low or absent numbers of mature B lymphocytes, as well as low or absent expression of the µ heavy chain on the surface of the lymphocyte. (medscape.com)
Having a maternal uncle or male cousin with absent B cells makes the diagnosis almost certain. (nih.gov)
Diagnosis of X-linked agammaglobulinemia is by detecting low (at least 2 standard deviations below the mean) levels of immunoglobulins (IgG, IgA, IgM) and absent B cells ( 1% of all lymphocytes are CD19 + cells, detected by flow cytometry). (msdmanuals.com)
Usually, absent CD19 + B cells in a male with hypogammaglobulinemia is sufficient to make the diagnosis, especially if there is a positive family history. (medscape.com)
Hypogammaglobulinemia2
Agammaglobulinemia, or hypogammaglobulinemia, is the most common of the primary immunodeficiencies, accounting for approximately 50% of cases. (medscape.com)
Genetic loss of BTK, as occurs in X-linked agammaglobulinemia, results in the absence of B cells and hypogammaglobulinemia. (haematologica.org)
Colonel Bruton's kinase defined the molecular basis of X-linked agammaglobulinemia, the first primary immunodeficiency. (medscape.com)
Thrombocytopenia2
The American Society of Hematology defines it as an isolated thrombocytopenia with clinically no apparent associated conditions or no other cause of thrombocytopenia, such as HIV infection, systemic lupus erythematosus, lymphoproliferative disorders, myelodysplasia, agammaglobulinaemia or hypogammaglobulinaemia, drug-induced thrombocytopenia, alloimmune thrombocytopenia or congenital/hereditary non-immune thrombocytopenia [7]. (who.int)
He had agammaglobulinemia, normal lymphocyte counts, intermittent thrombocytopenia, mildly low hemoglobin, and low MCV (Supplementary Furniture 2 and 3). (sipurpashut.net)
Immunoglobulins1
X-linked agammaglobulinemia is characterized by low levels or absence of immunoglobulins and absence of B cells, leading to recurrent infections with encapsulated bacteria. (msdmanuals.com)
X-linked agammaglobulinemia (XLA) is characterized by recurrent bacterial infections in affected males in the first two years of life. (nih.gov)
IgA more than 2 SD below normal for age Absent isohemagglutinins Spectrum of disease Most patients with XLA develop recurrent bacterial infections , particularly otitis, sinusitis and pneumonia, in the first two years of life. (symptoma.com)
CD192
In patients with no other affected family members, autosomal forms of agammaglobulinemia must be considered when the CD19 expression on B cells is minimal in a male patient (although 30-50% of XLA cases are believed to arise from new mutations). (medscape.com)
Mutations in the genes for the for the µ heavy chin, Igα, Igβ, λ, B-cell linger (BLNK), leucine-rich repeat-containing 8 (LRRC8), CD79a, transcription factor E47, or the p85α subunit of phosphoinositide 3-kinase (PL13K) are unusual etiologies for agammaglobulinemia with absent CD19 + B cells.

Absence1
Agammaglobulinemia means an absence of gamma globulin in the blood. (mbbch.com)

After more than 50 years since the clinical entity was first described by Bruton in 1952, the molecular defect in X-linked agammaglobulinemia (XLA) has been elucidated. (medscape.com)

Patients have either persistently absent or markedly low neutrophil counts. (unboundmedicine.com)
Antibody2
Without mature B lymphocytes, antibody-producing plasma cells are also absent. (medscape.com)
Agammaglobulinemia with absent B cells, including X-linked (Btk insufficiency) and autosomal recessive forms, hyper-IgM syndromes, and various other major antibody deficiencies, had been excluded by molecular research. (citiesofdata.org)

Growth hormone deficiency associated with absent B cells is rare. (medscape.com)
Benign "partial ADA deficiency" (very low or absent ADA activity in erythrocytes but greater ADA activity in nucleated cells), which is compatible with normal immune function. (beds.ac.uk)
Disorders1
Immunodeficiency disorders occur when the body's immune response is reduced or absent. (medlineplus.gov)
Disease1
Agammaglobulinemia, usually abbreviated as AGMX, is a disease with a genetic origin. (mbbch.com)
Severe1
Dampened reverse flow suggests the presence of ste- nosis and with severe stenosis or occlusion the reverse flow is absent. (binaryoptiontradingscam.com)
Infections1
The main manifestation of primary immunodeficiency in children is an abnormal susceptibility to infections, in which other manifestations of immune deficiency may be small or absent. (stop-seizures-meds.com)
Gene2
Agammaglobulinemia only needs a single bad copy of a gene to express itself. (mbbch.com)
If the person has just one mutated gene that codes for either a reduced production or absent production of beta globin chains, then they have beta thalassemia minor. (osmosis.org)
