The t(8;21)(q22;q22) translocation involving RUNX1 at 21q22 and RUNX1T1 at 8q22 is found in 10% of cases of acute myeloid leukemia (AML) M2 subtype. This translocation results in the formation of a RUNX1/RUNX1T1 fusion gene, which contributes to leukemic transformation by transcriptional repression of normal RUNX1 target genes, on der (8)t(8;21)(q22;q22). AML with t(8;21) is usually associated ...

Cytogenetic studies were done in two cases of Burkitt's lymphoma in homosexual individuals with possible acquired immune deficiency syndrome (AIDS). The chromosomal abnormalities found are consistent with those previously described in the nonendemic form of Burkitt's lymphoma, with one of the two patients having the variant translocation, t(8;22). The production of the kappa light chain immunog...

BACKGROUND AND OBJECTIVES Around 5% of chronic myeloid leukemias (CML) are characterized by complex variant Philadelphia (Ph) translocations involving one or more chromosomal regions in addition to 9 and 22. The BCR/ABL1 fusion gene is usually found on der(22). The additional gene(s) involved in complex variant Ph rearrangements have not been characterized. DESIGN AND METHODS We performed flu...

Chronic myeloid leukemia (CML) is genetically characterized by the presence of the reciprocal translocation t(9;22) with the formation of Philadelphia (Ph) chromosome. Sometimes, the Ph translocation is generated by variant rearrangements. The prognostic impact of the variant translocations is still controversial. Among the 180 patients with Ph-positive CML who were treated in Hacettepe Univers...

Most chronic myeloid leukemia (CML) patients show the Philadelphia chromosome (Ph) arising from the reciprocal t(9;22), but 5-10% present variants of this translocation involving different breakpoints besides 9q34 and 22q11. WE REPORT THE NON SIMULTANEOUS OCCURRENCE OF TWO DIFFERENT TYPES OF PH TRANSLOCATION IN A CML PATIENT: a t(9;22)(q34;q11) standard and a three-way variant t(9;11;22)(q34;p1...

in this paper. (1) we determine the complex-valued solutions of the following variant of van vleck's functional equation $$int_{s}f(sigma(y)xt)dmu(t)-int_{s}f(xyt)dmu(t) = 2f(x)f(y), ;x,yin s,$$ where $s$ is a semigroup, $sigma$ is an involutive morphism of $s$, and $mu$ is a complex measure that is linear combinations of dirac measures $(delta_{z_{i}})_{iin i}$, such that for all $iin i$,...
