Farlex Partner Medical Dictionary © Farlex 2012


A gene on chromosome Xq21.33-q22 that encodes a protein which plays a central role in B-cell development, differentiation and signalling. Binding of antigens to the B-cell antigen receptor (BCR) triggers signalling that leads to B-cell activation. 

Molecular pathology
Defects of BTK cause X-linked agammaglobulinaemia (OMIM:300755), as well as X-linked hypogammaglobulinaemia and isolated growth hormone deficiency (OMIM:307200).
