 MoSt GeNe/Genetic Drift/Molecular Cytogenetics (FISH)/FISH Applications in Cancer Cytogenetics
In these cases traditional cytogenetic analysis is more likely to identify the karyotype of the normal dividing cells, and may miss the rare abnormal cell in mitosis.
When only a single abnormal cell is observed in the course of a cytogenetic analysis, FISH on interphase cells may be used to confirm the presence of an abnormal clone, if the appropriate probe is available and if the laboratory has established normal ranges for that probe.
If a cytogenetic abnormality has been identified at diagnosis and a FISH probe is available to detect that abnormality, FISH may be used to screen interphase cells in subsequent studies.
