| Gene Variant Descriptions | BTK L528W lies within the protein kinase domain of the Btk protein (UniProt.org). L528W confers resistance to BTK inhibitors in culture (PMID: 35196427, PMID: 36183831, PMID: 39728925), results in loss of kinase activity in in vitro assays (PMID: 36183831, PMID: 38301010), increased calcium ion flux and decreased Btk and Plcg2 phosphorylation in culture (PMID: 35196427), but retains downstream signaling (PMID: 35196427) and calcium ion flux similar to wild-type in a different study (PMID: 36183831), and therefore, its effect on Btk protein function is unknown. |
