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

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.
Clinical Application of FISH
Back to Basic
 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
