In this report we describe a Ph chromosome- negative CML patient with trisomy of chromosome 8 as the single cytogenetic abnormality and a typical e14a2 (b3a2) BCR-ABL1 fusion transcript, with an unusual FISH signal pattern due to the presence of fusion signals on both copies of chromosome 22.

Background: Philadelphia (Ph) chromosome results from the reciprocal translocation t(9;22)(q34.1;q11.2) and is diagnostic for chronic myeloid leukemia (CML). However, this translocation is also found in acute lymphoid leukemia (ALL), as well as in rare cases of acute myeloid leukemias (AML).

Although various breakpoints within the BCR and ABL1 genes have been described, more than 95% of CMLs contain a consistent mRNA transcript in which either the BCR exon 13 (e13) or BCR exon 14 (e14) is fused to the ABL1 exon 2 (a2), yielding fusion forms e13/a2 and e14/a2, respectively. Chronic myeloid leukemia (CML) is a clonal myeloproliferative neoplasia characterized by the BCR-ABL1 fusion gene, derived from the t (9;22) translocation causing the Philadelphia Chromosome (Ph BCR/ABL1–like acute lymphoblastic leukemia (ALL) accounts for 15% to 30% of B‐lineage ALL, with a peak of incidence occurring in adolescence.This subgroup of patients is characterized by a peculiar transcriptional profile that resembles that of true BCR/ABL1–positive cases, and have a heterogeneous genetic background and a poor outcome. Probes: ABL1 (9q34); ASS1 (9q34; BCR (22q11.2) Disease(s): CML, ALL, MPN Note: For suspected ALL, STAT processing is available by request. Note STAT along with MD contact name and phone number to receive STAT results. Bcr-Abl tyrosine-kinase inhibitors (TKI) are the first-line therapy for most patients with chronic myelogenous leukemia (CML). More than 90% of CML cases are caused by a chromosomal abnormality that results in the formation of a so-called Philadelphia chromosome.

is a useful tool for diagnostic ascertainment in the case of a 'masked Philadelphia' chromosome, where chromosomes 9 and 22 all appear to be normal, but where cryptic insertion of 3' ABL within a chromosome 22 can be demonstrated : Cryptic insertion of BCR within chromosome 9.

The result is that a fusion gene is created by juxtaposing the ABL1 gene on chromosome 9 (region q34) to a part of the BCR (breakpoint cluster region) gene on chromosome 22 (region q11). BCR-ABL1 refers to a gene sequence found in an abnormal chromosome 22 of some people with certain forms of leukemia. Unlike most cancers, the cause of chronic myelogenous leukemia (CML) and some other leukemias can be traced to a single, specific genetic abnormality in one chromosome.

It is present in 3–4% of pediatric acute lymphoblastic leukemia (Ph+ ALL), and about 25% of adult ALL cases.

BCR and ABL1 genes and to generate a BCR/ABL1 fusion gene encoding a protein with increased tyrosine kinase activity. The BCR/ABL1 fusion gene has since been studied extensively, and shown to induce expansion of the leukemic cell population by mediating growth-promoting and death-inhibiting signals, but the mechanisms by which BCR/ABL1 elicits

In this report we describe a Ph chromosome- negative CML patient with trisomy of chromosome 8 as the single cytogenetic abnormality and a typical e14a2 (b3a2) BCR-ABL1 fusion transcript, with an unusual FISH signal pattern due to the presence of fusion signals on both copies of chromosome 22. The resulting chromosome 22 that has the BCR-ABL1 gene sequence is known as the Philadelphia (Ph) chromosome because that is where it was first discovered.

The materials consist of 4 different dilutions of K562 cells (Philadelphia chromosome positive) in HL60 cells (Philadelphia chromosome negative).
