Genomic Sequencing Technologies: A Review of Their Role in Precision Medicine
Introduction
Genomic sequencing technologies have revolutionized the field of precision medicine, allowing for a deeper understanding of genetic underpinnings in health and disease. By providing detailed insights into an individual’s genetic makeup, these technologies facilitate tailored treatment plans that are specific to a patient's unique genetic profile. This review explores the advancements in genomic sequencing technologies, their applications in precision medicine, and the implications for patient care.
Overview:
Genomic sequencing involves determining the complete DNA sequence of an organism’s genome. The two primary types of sequencing technologies are:
Sanger Sequencing: The traditional method that provides high accuracy and is typically used for smaller-scale projects or confirmatory analyses.
Next-Generation Sequencing (NGS): A high-throughput method that allows for the rapid sequencing of large amounts of DNA, making it suitable for comprehensive genomic studies.
