Rearrangement of immunoglobulin heavy chain genes in T cell acute
lymphoblastic leukemia
GR Kitchingman, U Rovigatti, AM Mauer, S Melvin, SB Murphy and S Stass
We studied the arrangement of the immunoglobulin heavy chain genes by
Southern blot analysis of DNA freshly obtained from marrow blast cells of
14 children with T cell acute lymphoblastic leukemia (T-ALL) using probes
to the C mu and JH gene segments: At least one of the C mu-gene alleles was
rearranged in three cases. In two of these, one C mu gene had the germ-line
configuration and one was rearranged, whereas both alleles were rearranged
in the third case. In one case, a rearranged heavy chain gene hybridized to
the C mu-region probe, but not to the JH probe, indicating that the entire
JH region had been deleted. These results demonstrate that immunoglobulin
heavy chain gene rearrangements are not restricted to B lineage
lymphoproliferative diseases in humans.
