Implementation of a next-generation sequencing-based targeted approach for full-length CYP3A4 gene sequencing

Area of Science:

• Pharmacogenomics
• Molecular Biology
• Genetics

Background:

• The CYP3A4 gene plays a crucial role in drug metabolism.
• Understanding CYP3A4 genetic variations is important for personalized medicine.
• Accurate sequencing of the entire CYP3A4 gene is essential for comprehensive analysis.

Purpose of the Study:

• To assess a next-generation sequencing (NGS) targeted protocol for full-length CYP3A4 gene sequencing.
• To validate the protocol's efficacy in detecting genetic variants within the CYP3A4 gene.

Main Methods:

• A targeted NGS protocol was developed and applied.
• Human DNA samples (n=7) from tuberculosis patients were analyzed.
• Sequencing data quality was evaluated for variant detection.

Main Results:

• The protocol generated high-quality sequencing data for the CYP3A4 gene.
• The method successfully identified known, rare, and novel genetic variants.
• High confidence in variant detection across the entire gene was achieved.

Conclusions:

• The developed NGS protocol is suitable for full-length CYP3A4 gene sequencing.
• This protocol can be utilized in subpopulation association studies.
• It aids in determining the clinical significance of CYP3A4 genetic variants and their combinations.
