|Gene Variant Descriptions||ABL1 T315I is a gatekeeper mutation that lies within the hinge region of the protein kinase domain of the Abl1 protein (PMID: 18794843). T315I has been demonstrated to occur as a secondary resistance mutation and results in increased kinase activity and transformation in the context of BCR-ABL1 in cell culture (PMID: 11423618, PMID: 18794843, PMID: 27890928), and results in reduced catalytic efficiency (kcat/km) in an in vitro assay (PMID: 30684523), but has not been fully characterized and therefore, its effect on Abl1 protein function is unknown.|
