Single-cell analysis reveals multi-hit TP53 mutations in AML, suggesting challenges in venetoclax therapy.

To characterize the clonal dynamics and lineage associations of TP53 mutated AML using single-cell sequencing.
Analyzed 17 bone marrow samples from 9 patients with TP53m AML using single-cell DNA and protein sequencing.
Utilized next-generation sequencing and tested for multi-hit TP53 abnormalities.
Performed enrichment of CD34/117+ cells for a more detailed analysis.
Identified multi-hit TP53 abnormalities mainly in AML blasts, often showing loss of heterozygosity.
Found a minor ancestral TP53 heterozygous population in the blast compartment.
Detected selective expansion of TP53m multi-hit clones in patients undergoing venetoclax therapy.

Cervera et al. (2025) studied this question.
