Translocation (14;14)(q11;q32) was associated with acute lymphoblastic leuk
emia in a child. The B-cell lineage of the leukemic cells led us to perform
FISH studies, which showed that the chromosomal breakpoints were telomeric
to TCRA/D and IGH loci. These findings show that FISH analyses are necessa
ry when unusual features are associated with a recurrent translocation. (C)
