Abstract

BACKGROUND: Myelodysplastic syndromes are clinically heterogeneous disorders characterized by clonal hematopoiesis, impaired differentiation, peripheral-blood cytopenias, and a risk of progression to acute myeloid leukemia. Somatic mutations may influence the clinical phenotype but are not included in current prognostic scoring systems. METHODS: We used a combination of genomic approaches, including next-generation sequencing and mass spectrometry-based genotyping, to identify mutations in samples of bone marrow aspirate from 439 patients with myelodysplastic syndromes. We then examined whether the mutation status for each gene was associated with clinical variables, including specific cytopenias, the proportion of blasts, and overall survival. RESULTS: We identified somatic mutations in 18 genes, including two, ETV6 and GNAS, that have not been reported to be mutated in patients with myelodysplastic syndromes. A total of 51% of all patients had at least one point mutation, including 52% of the patients with normal cytogenetics. Mutations in RUNX1, TP53, and NRAS were most strongly associated with severe thrombocytopenia (P<0.001 for all comparisons) and an increased proportion of bone marrow blasts (P<0.006 for all comparisons). In a multivariable Cox regression model, the presence of mutations in five genes retained independent prognostic significance: TP53 (hazard ratio for death from any cause, 2.48; 95% confidence interval [CI], 1.60 to 3.84), EZH2 (hazard ratio, 2.13; 95% CI, 1.36 to 3.33), ETV6 (hazard ratio, 2.04; 95% CI, 1.08 to 3.86), RUNX1 (hazard ratio, 1.47; 95% CI, 1.01 to 2.15), and ASXL1 (hazard ratio, 1.38; 95% CI, 1.00 to 1.89). CONCLUSIONS: Somatic point mutations are common in myelodysplastic syndromes and are associated with specific clinical features. Mutations in TP53, EZH2, ETV6, RUNX1, and ASXL1 are predictors of poor overall survival in patients with myelodysplastic syndromes, independently of established risk factors.

  • TP53 gene mutations are detected in approximately 10%-20% of patients with de novo MDS or AML and 30%-40% of patients with therapy-related disease.

    “TP53 gene mutations are detected in approximately 10%-20% of patients with de novo myelodysplastic syndromes (MDS)1-4 or acute myeloid leukemia (AML)5,6 and 30%-40% of patients with therapy-related disease.7”

    From Eprenetapopt (APR-246) and Azacitidine in <i>TP53</i> -Mutant Myelodysplastic Syndromes (2021) · cites this paper as [4]

    The cited paper is attached to the de novo MDS portion of the sentence, not the AML or therapy-related estimates. Its Results report 33 TP53-mutant samples among 439 MDS samples (about 7.5%), but do not give a 10%–20% rate specifically for de novo MDS. The paper supports detection of TP53 mutations in MDS, not the attributed prevalence estimate. (LLM, conf=0.83)

  • TP53 gene mutations (mTP53) represent a distinct molecular cohort with poor outcomes.

    “TP53 gene mutations (mTP53) represent a distinct molecular cohort with poor outcomes.”

    From Long‐term follow‐up and combined Phase 2 results of eprenetapopt and azacitidine in patients with <i>TP53</i> mutant MDS/AML (2025) · cites this paper as [2]

    The Discussion says TP53 mutations were strongly associated with shorter overall survival after adjustment for IPSS risk group. It suggests a distinct molecular subclass specifically for patients with both mutant TP53 and a complex karyotype, not for all patients with TP53 mutations. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • mTP53 is found in up to 20% of MDS/AML and 30-40% of therapy-related MDS/AML cases.

    “TP53 gene mutations (mTP53) are found in up to 20% of myelodysplastic syndromes/neoplasms (MDS) or acute myeloid leukemia (AML) pts and 30%–40% of therapy‐related (TR) MDS/AML cases”

    From Long‐term follow‐up and combined Phase 2 results of eprenetapopt and azacitidine in patients with <i>TP53</i> mutant MDS/AML (2025) · cites this paper as [2]

    The Results section reports 33 TP53-mutant MDS samples, supporting the claim that TP53 mutations occur in MDS. It does not establish an 'up to 20%' rate for MDS or AML, and no passage found reports a 30–40% rate in therapy-related MDS/AML; searches targeted those percentages and therapy-related disease. Page numbers were not available in our copy. (LLM, conf=0.83)

  • Many of the most commonly seen mutations in CHIP are also recurrent drivers of AML, myelodysplastic syndrome (MDS), myeloproliferative neoplasms, and certain lymphomas.

    “But many of the most commonly seen mutations in CHIP are also recurrent drivers of AML 64, myelodysplastic syndrome (MDS) 65–67, myeloproliferative neoplasms 68, and certain lymphomas 69,70.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
