Samples of leukemic cell DNA from 14 children with
acute nonlymphocytic leukemia
(
ANLL
) and 4 human myeloid leukemia cell lines were analyzed for rearrangement in the heavy chain region of the immunoglobulin gene. The diagnosis of
ANLL
was confirmed in all patients by morphological, cytochemical, and immunologic studies. By restriction
endonuclease
digestion and hybridization with cloned heavy chain immunoglobulin gene probes for the constant (Cmu) and joining (JH) regions, the DNA of 2 patients and 1 cell line (ML-1) was found to contain rearrangements. The DNA from the remaining 12 patients and 3 cell lines was not rearranged (germline configuration). Both patients with apparent immunoglobulin gene rearrangement achieved complete remission on therapy for
ANLL
. Immunoglobulin gene rearrangement in phenotypically defined
ANLL
suggests (1) that such changes may not be limited to lymphoid leukemia of B cell lineage, or (2) that, in some patients, the leukemic transforming event may involve stem cells capable of both B cell and myeloid differentiation.
