Clinics and Pathology

Note

Only 4 cases to date, 3 of which do not provide further descriptions.

Phenotype stem cell origin

All cases were acute myeloid leukaemia (AML); AML-M0 (1 case), AML-M2 (1 case), AML-M4 (2 cases).

Epidemiology

All patients were female between the ages of 13 to 68 years.

Bone marrow morphology from AML-M2 case with t(6;11)(q15;q23).

Prognosis

Very poor in 1 case (survival : only 2 weeks in AML-M2).

Cytogenetics

Cytogenetics morphological

It shows distinct balanced chromosomal abnormalities between chromosomes 6 and 11; however, it should be differentiated from t(6;11)(q13;q23) in association with MLL/ SMAP1 rearrangement.

Cytogenetics molecular

MLL breakapart FISH probe is very useful.

Additional anomalies

del(5)(q13q15) in 1 case, sole abnormality in remaining 3 cases.

Genes Involved and Proteins

Note
The gene involved in 6q15 is unknown.
Gene name
KMT2A (myeloid/lymphoid or mixed lineage leukemia)
Location
11q23.3
Note
More than 50 different translocation fusion partners in association with the MLL gene have been reported in the literature. In chromosome 6, t(6;11)(q27;q23) (MLL/AF6 rearrangement) is the most commonly encountered chromosomal abnormality. In contrast, t(6;11)(q13;q23) or t(6;11)(q15;q23) is the rarest type of MLL rearrangement involving the long arm of chromosome 6.

Result of the Chromosomal Anomaly

Note

Unknown. However, MLL/SMAP1 rearrangement was excluded in one case by both our group and Dr. Meyer.Unknown.
