The Philadelphia chromosome or Philadelphia translocation Ph is a specific genetic abnormality in chromosome 22 of leukemia cancer cells particularly chronic myeloid leukemia CML cells. Hence the chromosome breakpoints are written as 9q International Journal of Hematology. Three clinically important variants encoded by the fusion gene are the p, p, and p isoforms.

The function of these pro-apoptotic proteins, however, is impaired, and apoptosis is not carried out in these cells. InJanet Rowley at the University of Chicago identified the mechanism by which the Philadelphia chromosome arises as a translocation.

This chromosome is defective and unusually short because of reciprocal translocationt 9;22 q34;q11of genetic material between chromosome 9 and chromosome 22and contains a fusion gene called BCR-ABL1.

AML Acute panmyelosis with myelofibrosis Myeloid sarcoma. New inhibitors include dasatinib and nilotinibwhich are significantly more potent than imatinib and may overcome philadelphei.

Philadelphia chromosome

Although it did not eradicate CML cells, it did greatly limit the growth of the tumor clone and decreased the risk of the feared ” blast crisis “.

Moreover, it inhibits DNA repaircausing genomic instability and potentially causing the feared blast crisis in CML. The result is that a fusion gene is created by juxtaposing the ABL1 gene philadelpphie chromosome 9 region q34 to a part chroosome the BCR breakpoint cluster region gene on chromosome 22 region q Glossaries and vocabularies Access Translation Bureau glossaries and vocabularies.


A good correlation is observed between cytogenetic and FISH results in patients at diagnosis or under treatment. FISH is usefull for detecting cryptic or variant translocations, or for assessing the remission rate when cytogenetics is unsuccesfull.

Hungerford was writing his doctoral thesis on chromosomes in a genetics lab at Fox Chase Cancer Center, and detected a tiny flaw in chromosomes from the blood cells of curomosome with a type of leukemia.

This is due to the replacement of the myristoylated cap region, which when present induces a conformational change rendering the kinase domain inactive, with a truncated portion of the BCR protein. Journal of Biological Chemistry. Depending on the precise location of fusion, cheomosome molecular weight of this protein can range from to kDa.

The need of quantitative methods is evident, but technical problems in standardization limits its application for residual disease evaluation. This is a reciprocal translocation, creating an elongated chromosome 9 termed philadelphle derivative chromosome, or der 9and a truncated chromosome 22 the Philadelphia chromosome, 22q.

The symbol ABL is derived from Abelsonthe name of a leukemia virus which carries a similar protein. From Wikipedia, the free encyclopedia. Monosomy Turner syndrome 45,X. Phiadelphie majority of these resistant clones are point-mutations in the kinase of BCR-abl. The symbol BCR is derived from breakpoint cluster region, a gene which encodes a protein that acts as a guanine nucleotide exchange factor for Rho GTPase proteins.
