X-chromosome. Most antibodies are gamma globulins. Antibodies are made mainly by plasma cells, which are daughter cells of the B cell line.The Btk enzyme plays an essential role in the maturation of B cells in the bone marrow, and when mutated, immature pro-B lymphocytes are unable to develop into pre-B lymphocytes, which normally develop into mature (naive) B cells that leave the bone marrow ...
Bruton's tyrosine kinase is named for Ogden Bruton, who first described XLA in 1952. [10] [40] Later studies in 1993 and 1994 reported the discovery of BTK (initially termed B cell progenitor kinase or BPK) and found that BTK levels are reduced in B cells from XLA patients. [41] [42] [43]
This type of agammaglobulinemia is now called Bruton's syndrome or X-linked agammaglobulinemia, which was later found by others to be an X-linked congenital condition. The gene defect has since been mapped to the gene code for Bruton's tyrosine kinase (Btk), at band Xq21.3. [3] [6]
X-linked agammaglobulinemia was one of the first described primary immunodeficiencies, discovered by Ogden Bruton in 1952. [4] [20] Primary immunodeficiencies were initially classified in 1970 by a committee of the World Health Organization. At the time, they identified 16 immunodeficiencies. By 1998, the number had reached 50. [21]
Severe combined immunodeficiency (SCID), also known as Swiss-type agammaglobulinemia, is a rare genetic disorder characterized by the disturbed development of functional T cells and B cells caused by numerous genetic mutations that result in differing clinical presentations. [2]
Dysgammaglobulinemia is a type of immune disorder characterized by a reduction in some types of gamma globulins, resulting in heightened susceptibility to some infectious diseases where primary immunity is antibody based.
