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). This chromosome is defective and unusually short because of reciprocal translocation , t(9;22)(q34;q11), of genetic material between chromosome 9 and ...
Additional clonal chromosomal abnormalities in Philadelphia (Ph) chromosome-positive (Ph+) cells at diagnosis, including so-called major route abnormalities (a second Ph chromosome, trisomy 8, isochromosome 17q, trisomy 19), complex karyotype, and abnormalities of 3q26.2; Any new clonal chromosomal abnormality in Ph+ cells that occurs during ...
PPARγ1 [13] (peroxisome proliferator-activated receptor γ 1) on chromosome 3 t(8;21)(q22;q22) [12] Acute myeloblastic leukemia with maturation: ETO on chromosome 8: AML1 on chromosome 21 found in ~7% of new cases of AML, carries a favorable prognosis and predicts good response to cytosine arabinoside therapy [12] t(9;22)(q34;q11) Philadelphia ...
However the lack of the pathognomonic Philadelphia chromosome [2] and of the resulting BCR-ABL1 fusion point to a different pathogenetic process. Since no specific recurrent genomic or karyotypic abnormalities have been identified in aCML, the molecular pathogenesis of this disease has remained elusive and the outcome dismal (median survival 37 ...
Acute lymphoblastic leukemia (ALL) is a cancer of the lymphoid line of blood cells characterized by the development of large numbers of immature lymphocytes. [1] Symptoms may include feeling tired, pale skin color, fever , easy bleeding or bruising, enlarged lymph nodes , or bone pain. [ 1 ]
A translocation between chromosomes 9 and 22, known as the Philadelphia chromosome, occurs in about 20% of adult and 5% in pediatric cases of ALL. A translocation between chromosomes 4 and 11 occurs in about 4% of cases and is most common in infants under 12 months. Not all translocations of chromosomes carry a poorer prognosis.

She and her co-workers identified several novel chromosome changes in leukemia and lymphoma, and discovered that these abnormalities are among the most important factors that determine a patient's prognosis. For example, Bloomfield was involved in the discovery of the Philadelphia chromosome in patients with acute lymphoblastic leukemia (ALL). [3]
