The Human Genome Project identified millions of DNA variants, mostly single nucleotide polymorphisms (SNPs). Current SNP genotyping methods are reviewed, highlighting challenges and future directions for genetic studies of complex diseases.

Area of Science:

  • Genomics
  • Molecular Biology
  • Human Genetics

Background:

  • The Human Genome Project has revealed millions of DNA sequence variants, predominantly single nucleotide polymorphisms (SNPs).
  • SNPs are crucial genetic markers for investigating the genetic underpinnings of complex diseases using population-based studies.
  • Large-scale genotyping of numerous individuals with a high density of SNP markers is essential for these studies.

Purpose of the Study:

  • To review the current state of single nucleotide polymorphism (SNP) genotyping technologies.
  • To discuss the mechanisms, formats, and detection methods employed in SNP genotyping.
  • To identify current challenges and future prospects in SNP genotyping for genetic research.

Main Methods:

  • Review of existing SNP genotyping methodologies.
