Activating mutations in ALK kinase domain confer resistance to structurally unrelated ALK inhibitors in NPM-ALK-positive anaplastic large-cell lymphoma
Excerpt:
cDNA sequencing of ALK kinase domain revealed activating mutations—I1171T in Karpas299CR and F1174C in Karpas299CHR. The resistant cells displayed diminished sensitivity to structurally unrelated ALK inhibitors—crizotinib, CH5424802 and TAE684.
