Bruton agammaglobulinemia tyrosine kinase (BTK) is a gene that encodes a protein that functions in B-cell development. Missense, nonsense, and silent mutations are observed in cancers such as endometrial cancer, intestinal cancer, and skin cancer.

BTK is altered in 0.93% of all cancers with lung adenocarcinoma, colon adenocarcinoma, breast invasive ductal carcinoma, cutaneous melanoma, and endometrial endometrioid adenocarcinoma having the greatest prevalence of alterations [3].

The most common alterations in BTK are BTK Mutation (0.59%), BTK Loss (0.08%), BTK Amplification (0.03%), BTK E488K (0.01%), and BTK R123W (0.01%) [3].
