Principles of the Polymerase Chain Reaction in Haematology

Area of Science:

• Molecular Biology
• Genetics
• Biotechnology

Background:

• Genetic alterations like mutations, deletions, inversions, and translocations can lead to non-functional genes or aberrant gene expression.
• Many genetic abnormalities are increasingly associated with specific diseases.
• Early detection of genetic lesions is crucial for disease diagnosis and monitoring.

Purpose of the Study:

• To highlight the diagnostic and prognostic utility of Polymerase Chain Reaction (PCR) in detecting genetic alterations.
• To emphasize PCR's capability in identifying abnormal cells and genetic polymorphisms for disease prediction.

Main Methods:

• Automated amplification of selected DNA sequences using Polymerase Chain Reaction (PCR).
• Detection of genetic changes indicative of disease onset.
• Identification of naturally occurring genetic polymorphisms.

Main Results:

• PCR enables the detection of genetic alterations associated with diseases, serving as a diagnostic and prognostic tool.
• Genetically abnormal cells can be identified at significantly lower incidence levels compared to other technologies.
• Genetic polymorphisms can be identified for individual identification and disease inheritance prediction.

Conclusions:

• PCR is a powerful tool for diagnosing and monitoring diseases caused by genetic abnormalities.
• The sensitivity of PCR allows for the detection of rare abnormal cells within normal populations.
• PCR facilitates the prediction of disease carrier status and inheritance likelihood through polymorphism analysis.
