Area of Science:

  • Genetics
  • Molecular Biology
  • Medical Research

Background:

  • Multifactorial diseases necessitate the analysis of numerous gene loci and patient samples.
  • Conventional screening methods are often insufficient for complex genetic analyses.
  • Simple repetitive DNA markers are widely dispersed across chromosomes.

Purpose of the Study:

  • To validate the concept of indirect gene diagnosis using simple, tandemly arranged, repetitive DNA sequences.
  • To demonstrate the application of microsatellite technologies in analyzing multifactorial diseases.
  • To compare the advantages of microsatellite technologies against multilocus DNA fingerprinting.

Main Methods:

  • Utilizing molecular techniques based on simple, tandemly arranged, repetitive DNA sequences (microsatellites).
