  7. Philadelphia Chromosome (=Ph) der(22)t(9;22)(q34.1;q11.21) q11.2 BCR q34 ABL Ph (formerly Ph1) may be used in text, but not in the description of the karyotype, where der(22)t(9;22)(q34;q11.2) is recommended.

  8. 50,XX,+8,t(9;22)(q34;q11.2),+10,+19,+der(22)t(9;22)(q34.1;q11.21)50,XX,+8,t(9;22)(q34;q11.2),+10,+19,+der(22)t(9;22)(q34.1;q11.21) CML Blast Crisis - Karyotype

  9. Practical Use of Cytogenetics in CML • Advantages ofCytogentics, compared to molecular DNA studiesfor BCR gene rearrangement • Distinguish betwn variant Ph and standard t(9;22) • Dectect other abnormalities : +8, i(17q),+Ph,+19 • Predict or confirm blast crisis • Give information regarding percentage of normal vs abnormal cells • Valuable after BMT to follow engraftment of the donor cells and identify possible relapse

  25. Cytogenetics Technologies Karyotyping Provides a visual examination of the entire genome the best coverage but not the best resolution (≥ 5 Mb) Banding resolution differs from preparation to preparation FISH Sensitive (high resolution) Only provides information on tested regions, other aberrations will NOT be tested, i.e. not genome view M-FISH(Multi-FISH, Spectral karyotyping) Array-based Copy Number / CGH Analysis Single step global genome scan prevents FISHing expedition BAC (Bacterial Artificial Chromosome) Array Requires well characterized and high resolution clones High Resolution Oligonucleotide Microarray Highest resolution. Precise identification of gains and losses of genetic material.

  26. Clinical Application of FISH • Microdeletion syndromes • Prader-Willi/Angelman syndrome • DiGeorge/CATCH 22 syndrome • Williams syndrome etc. • Marker chromosome • Hematologic malignancies • t(9;22): abl/bcr • t(15;17): PML/RARa • 11q23: MLL • t(12;21): TEL/AML1 • BMT follow-up using X/Y
