Hematological malignancies.

Note

So far, the t(6;22)(p21;q11) is heterogeneous, and its significance remains problematic.

Phenotype stem cell origin

Four cases availble: one case was a myeloid type blast crisis of chronic myeloid leukemia (CML) in a 36-year-old male patient with a t(9;22)(q34;q11); another case was a CML aberrant translocation t(6;22)(p21;q11) without apparent involvement of chromosome 9 in a 44-year-old male patient; a third case was that of a B-cell precursor (CD10+) L1- acute lymphoblastic leukemia in a 2-year-old girl who was still in complete remission 72 months after diagnosis. A cryptic 5 ETV6 - 3 RUNX1 was found; there were accompanying anomalies, of which a +10 and a +21; the last case was a chronic lymphocytic leukemia (CLL) stage C with also a del(11q), and a del(13q).

Genes Involved and Proteins

Note
Genes involved, if any, are unknown.
