Molecular cytogenetics, using fluorescence in situ hybridization (FISH), enhances genetic diagnosis. This technology aids in identifying chromosomal abnormalities for better patient outcomes in various medical fields.

Area of Science:

  • Molecular biology
  • Genetics
  • Cytogenetics

Background:

  • Conventional chromosome analysis has limitations in detecting subtle genetic changes.
  • Molecular genetic technologies have expanded the understanding of chromosome structure and behavior.
  • Molecular cytogenetics offers advanced diagnostic capabilities.

Purpose of the Study:

  • To discuss the principles and clinical applications of fluorescence in situ hybridization (FISH).
  • To highlight FISH-derived technologies and their roles in genetic diagnostics.
  • To emphasize the diagnostic and prognostic value of FISH in various medical disciplines.

Main Methods:

  • Fluorescence in situ hybridization (FISH) for visualizing genetic loci.
  • Comparative genome hybridization (CGH).
