Molecular diagnostics detect gene mutations for various health conditions. Challenges include genetic diversity, costs, and physician education for accurate interpretation.

Area of Science:

  • Medical Genetics
  • Molecular Biology
  • Clinical Diagnostics

Background:

  • Molecular diagnostics identify pathogenic mutations in DNA/RNA for disease detection.
  • Advances in gene identification and mutation characterization drive new diagnostic test development.
  • Testing is indicated for diagnosis, carrier risk, prenatal, presymptomatic, and population screening.

Purpose of the Study:

  • To outline the principles and applications of molecular diagnostics in clinical settings.
  • To describe the unique role of genetic counselors in reference laboratories.
  • To identify key challenges in the implementation and practice of molecular diagnostics.

Main Methods:

  • Review of principles underlying DNA-based diagnosis.
  • Analysis of indications for molecular genetic testing.
