BTKbase, mutation database for X-linked agammaglobulinemia (XLA)
X-linked agammaglobulinemia (XLA) is an immunodeficiency caused by mutations in the gene coding for Bruton's agammaglobulinemia tyrosine kinase (BTK). A database (BTKbase) of BTK mutations has been compiled and the recent update lists 368 entries from 318 unrelated families showing 228 unique molecular events. In addition to mutations the database lists also some polymorphisms and site-directed...
متن کاملBruton tyrosine kinase (BTK) in X-linked agammaglobulinemia (XLA).
X-linked agammaglobulinemia (XLA) is a heritable immunodeficiency disorder that is caused by a differentiation block leading to almost complete absence of B lymphocytes and plasma cells. The affected protein is a cytoplasmic protein tyrosine kinase, Bruton's agammaglobulinemia tyrosine kinase (Btk). Btk along with Tec, Itk, Bmx and Txk belong to a distinct family of protein kinases. These prote...
متن کاملGenotype/phenotype correlations in X-linked agammaglobulinemia.
No clear genotype/phenotype correlations have been established in patients with X-linked agammaglobulinemia (XLA). To determine if the specific mutation in Btk might be one of the factors that influences the severity of disease or if polymorphic variants in Tec, a cytoplasmic tyrosine kinase that might substitute for Btk, could contribute to the clinical phenotype, we examined the age at diagno...
متن کاملDeletion within the Src homology domain 3 of Bruton's tyrosine kinase resulting in X-linked agammaglobulinemia (XLA)
The gene responsible for X-linked agammaglobulinemia (XLA) has been recently identified to code for a cytoplasmic tyrosine kinase (Bruton's agammaglobulinemia tyrosine kinase, BTK), required for normal B cell development. BTK, like many other cytoplasmic tyrosine kinases, contains Src homology domains (SH2 and SH3), and catalytic kinase domain. SH3 domains are important for the targeting of sig...
متن کاملX-linked agammaglobulinemia and rheumatoid arthritis
The pathogenic role of B cells in rheumatoid arthritis (RA) has recently gained much interest by the marked clinical responses of anti-CD20 therapy in RA. We describe a patient with X-linked agammaglobulinemia (XLA) who presented with an erosive symmetrical polyarthritis with histological features of RA including formation of a destructive pannus. Furthermore, the patient also developed subcuta...
