| Gene Variant Descriptions | BTK C481Y lies within the protein kinase domain of the Btk protein (UniProt.org). C481Y confers resistance to BTK inhibitors, results in a loss of Btk kinase activity in in vitro assays and in cell culture (PMID: 36183831, PMID: 35639855), but maintains BCR signaling through activation of Hck in culture (PMID: 35639855), and therefore, its effect on Btk protein function is unknown. |
