Bruton agammaglobulinemia tyrosine kinase

Btk, XLA, Bruton's tyrosine kinase, Xid
The protein encoded by this gene plays a crucial role in B-cell development. Mutations in this gene cause X-linked agammaglobulinemia type 1, which is an immunodeficiency characterized by the failure to produce mature B lymphocytes, and associated with a failure of Ig heavy chain rearrangement.
