| Protein Effect | loss of function |
| Gene Variant Descriptions | BTK C481R lies within the protein kinase domain of the Btk protein (UniProt.org). C481R confers a loss of function to the Btk protein as indicated by altered enzymatic activity in an in vitro assay (PMID: 27571029), decreased kinase activity in culture (PMID: 27282255), and decreased autophosphorylation and downstream signaling in culture (PMID: 27282255). |
