Monday 17 September 2007

Pathology

- ETV6-RUNX1-associated leukemia

  • Near-tetraploidy (82-94 chromosomes) makes up fewer than 1% of childhood acute lymphoblastic leukemia (ALL) cases and has been reportedly associated with a possibly poorer prognosis compared with other ploidy groups.

Cytogenetics

- Near-tetraploidy is a specific feature of ETV6/RUNX1+ BCP ALL (16552772).
