Abstract

Somatic mutations in DNMT3A, which encodes a de novo DNA methyltransferase, are found in ∼30% of normal karyotype acute myeloid leukemia (AML) cases. Most mutations are heterozygous and alter R882 within the catalytic domain (most commonly R882H), suggesting the possibility of dominant-negative consequences. The methyltransferase activity of R882H DNMT3A is reduced by ∼80% compared with the WT enzyme. In vitro mixing of WT and R882H DNMT3A does not affect the WT activity, but coexpression of the two proteins in cells profoundly inhibits the WT enzyme by disrupting its ability to homotetramerize. AML cells with the R882H mutation have severely reduced de novo methyltransferase activity and focal hypomethylation at specific CpGs throughout AML cell genomes.

  • Dnmt3a loss of function mutations comprise the majority of human clonal hematopoiesis-associated mutations.

    “Dnmt3a loss of function mutations, which comprise the majority of human CH-associated mutations (Russler-Germain et al., 2014)”

    From Chronic infection drives Dnmt3a-loss-of-function clonal hematopoiesis via IFNγ signaling (2021) · cites this paper as Russler-Germain et al., 2014

    The Discussion describes DNMT3A mutations that impair its function, and the Introduction reports DNMT3A mutation frequencies in acute myeloid leukemia (AML). Neither passage establishes that DNMT3A loss-of-function mutations comprise the majority of mutations associated with human clonal hematopoiesis; the reported population is AML, not clonal hematopoiesis.

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.
