abnormality

A 13-yr-old Japanese female with acute lymphoblastic leukemia (ALL) that
was associated with a Philadelphia chromosome (Ph1) as well as a 14q+
chromosome abnormality is reported. The cell surface phenotype of leukemic
cells was determined to be non-T, non-B ALL on the basis of positive
Ia-like antigen, terminal deoxynucleotidyl transferase activity, and lack
of receptors for sheep erythrocytes, surface immunoglobulin, or
intracytoplasmic mu-chain immunoglobulin. The combination of both a Ph1 and
a 14q+ has not been reported previously in patients with ALL.
