NOTCH 1 pathway activating mutations and clonal evolution in pediatric T‐cell acute lymphoblastic leukemia

Abstract excerpt

Molecular mechanisms involved in the relapse of T-cell acute lymphoblastic leukemia (T-ALL) are not fully understood, although activating NOTCH1 signaling due to NOTCH1/FBXW7 alterations is a major oncogenic driver. To unravel the relevance of NOTCH1/FBXW7 mutations associated with relapse, we performed whole-exome sequencing in 30 pediatric T-ALL cases, among which 11 diagnosis-relapse paired cases were further...
