Cytogenetics

Cytogenetics:
  • CML cases have the characteristic t(9;22) translocation called the Philadelphia chromosome which can be detected by karyotyping.
  • CML cases have the gene mutation BCR-ABL1 that can be detected by PCR (polymerase chain reaction) or NGS (next-generation sequencing), which is a DNA-based technology that tests for gene mutation.
  • The Philadelphia chromosome (BCR-ABL) can also be detected by fluorescent in situ hybridization (FISH), which is a dual color (orange & green) staining that can be examined and detected with a fluorescent microscope (fusion product appears yellow). The image to the right shows a normal cell pattern compared to a bcr/abl fusion pattern seen in CML.
