Clinics and Pathology


t(6;12)(p21;p13) has been described in only 6 cases: chronic lymphocytic leukemia (CLL); acute lymphoblastic leukemia (ALL), diffuse large B-cell lymphoma; acute myeloid leukemia (AML), NOS; myelodysplastic syndrome (MDS), RAEB-2; and breast adenocarcinoma.

Phenotype stem cell origin

B lineage.


No prognosis value established.


Cytogenetics morphological

May be not easy to detect.

Cytogenetics molecular

In CLL, the translocation was detected by FISH with ETV6 probes. The ETV6 gene is rearranged, and the breakpoint is between exon 1 and exon 2.

Additional anomalies

-9 and der(16)t(9;16)(q21;q24) in CLL; and del(7)(p13p22) in ALL.


No variants in CLL and ALL.

Result of the Chromosomal Anomaly


In CLL the ETV6 gene is rearranged; the breakpoint in ETV6 is between exon 1 and exon 2.
