Fluorescence in situ hybridization (FISH) enhances the study of congenital abnormalities in children. This technique offers greater resolution than traditional cytogenetics, aiding paediatricians in understanding genetic causes.

Area of Science:

  • Medical Genetics
  • Paediatric Diagnostics

Background:

  • Cytogenetics using banding techniques has identified chromosome abnormalities and phenotype-karyotype correlations since the 1970s.
  • A single chromosome band can encompass 20-50 genes, limiting resolution in conventional studies.

Purpose of the Study:

  • To clarify the current applications of Fluorescence In Situ Hybridization (FISH) in paediatric practice.
  • To highlight FISH's role in investigating the aetiology of congenital abnormalities in children.

Main Methods:

  • FISH analysis provides higher resolution than conventional cytogenetic banding.
  • FISH bridges the resolution gap between chromosomal studies and DNA-based analyses.

Main Results:

  • FISH enables deeper investigation into the causes of congenital abnormalities.

  • FISH offers improved diagnostic capabilities for paediatric genetic disorders.

    • Conclusions:

    • FISH is a valuable tool for paediatricians in diagnosing congenital abnormalities.
    • FISH enhances the understanding of genetic underpinnings of paediatric conditions.
