Single nucleotide polymorphism (SNP) detection technologies have advanced significantly, becoming more automated and cost-effective for both discovery and genotyping. Continued innovation is needed to further reduce costs and increase the speed of SNP detection.

Area of Science:

  • Genetics
  • Molecular Biology
  • Bioinformatics

Background:

  • Single nucleotide polymorphism (SNP) detection technologies have evolved from laborious, costly methods to highly automated, efficient, and affordable processes.
  • The Human Genome Project has driven the maturation of SNP discovery and genotyping technologies, providing a reference genome for comparison.
  • Current SNP discovery methods include direct DNA sequencing and denaturing high-performance liquid chromatography (dHPLC).

Purpose of the Study:

  • To review the evolution and current state of single nucleotide polymorphism (SNP) detection technologies.
  • To highlight advancements in SNP discovery and genotyping.
  • To identify the need for further development in SNP detection methods.

Main Methods:

  • Review of existing literature and technological advancements in SNP detection.

  • Analysis of the progression from labor-intensive to automated SNP detection processes.
  • Discussion of methodologies for both SNP discovery (global and local) and genotyping.

    • Main Results:

    • SNP detection technologies have become significantly more automated, efficient, and cost-effective.
    • Robust strategies for SNP discovery and genotyping are now widely available.
    • The demand for SNP genotyping is high, with numerous methods available, yet no single method universally meets all study needs.

    Conclusions:

    • Significant progress has been made in SNP detection technology over the past decade.
    • While robust methods exist, the high demand for SNP genotyping necessitates further development.
    • New approaches are required to further decrease the cost and increase the speed of SNP detection.
