Component

TET2 mutation frequency across human myeloid neoplasms

The proportion of patients in a sequenced series carrying a somatic TET2 deletion or mutation.

1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.

How nutrients influence it

Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.

How nutrients reach it in more than one step

Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does

Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.

What acts on it

  1. Sequencing the TET2 coding region in 320 patients found somatic deletions or mutations in 19% of myelodysplastic syndromes (15 of 81), 12% of myeloproliferative disorders (24 of 198), 24% of secondary acute myeloid leukaemia (5 of 21) and 22% of chronic myelomonocytic leukaemia (2 of 9).

    Experimental context and source evidence
    duration
    Cross-sectional
    experimental_model
    320 patients with myeloid cancers; molecular, cytogenetic, comparative-genomic-hybridization and SNP analyses
    exposure
    No intervention; observational sequencing of patient material
    limitations
    A mutation frequency is an association, not a demonstration that TET2 loss caused any of these cancers. Ascertainment was partly enriched: six patients were selected for 4q24 rearrangements and five for a JAK2 V617F-positive dominant clone.
    organism
    Homo sapiens
    plain_language
    About one in seven patients with these blood cancers carried a damaged copy of TET2.
