The e13a2 BCR-ABL1 Transcript Is Associated with Higher Rates of Molecular Recurrence after TFR attempts

ASH Abstract 1731

Conclusion: The factors that we identified as most predictive for TFR success were the duration of MR4.5 and the presence of the e14a2 transcript, which has not been described previously. We also observed earlier achievement of MR4.5 in the e14a2 cohort, consistent with other studies [Jain, Blood 2016]. These observations, taken together, raise important questions about the impact of transcript type on disease biology, drug sensitivity, and immunological response which warrant further investigation.
