Component

Order of TET2 and JAK2 V617F acquisition in human myeloproliferative clones

Which lesion was present first in the same patient's haematopoietic clone.

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 acts on it

  1. TET2 defects were present in haematopoietic stem cells and preceded the JAK2 V617F mutation in the five analysed samples from patients with myeloproliferative disorders.

    Experimental context and source evidence
    duration
    Cross-sectional
    experimental_model
    Five myeloproliferative-disorder patient samples with clonal analysis of progenitors
    exposure
    No intervention; clonal ordering within patient samples
    limitations
    Five samples. Order of acquisition in a clone does not by itself establish which lesion drives the disease.
    organism
    Homo sapiens
    plain_language
    Where both were present, the TET2 damage came first.
