Background:

Accurate detection of genomic mutations is crucial for diagnostics and research.
Existing mutation detection methods can be complex, time-consuming, or require specialized equipment.

Purpose of the Study:

To present a straightforward and efficient method for identifying known mutations in genomic DNA.
To introduce the Combined Chain Reaction (CCR) as a novel DNA amplification strategy.

Main Methods:

Developed a DNA amplification reaction combining thermostable DNA polymerase and ligase, termed Combined Chain Reaction (CCR).
CCR involves four phases: denaturation, annealing, elongation, and ligation.
Utilizes primer-template mismatch at the 5' ends of primers for mutation detection.

Main Results:

The Combined Chain Reaction (CCR) method enables detection of known mutations in genomic DNA.
CCR is a rapid and simple assay.
The technique avoids the need for radioactivity, polyacrylamide gel electrophoresis, or autoradiography.

Conclusions:

The Combined Chain Reaction (CCR) provides a simplified approach for single base-pair mutation detection.
This method offers a practical alternative to conventional mutation detection techniques.
CCR has potential applications in genetic testing and molecular diagnostics.
