Abstract
Single nucleotide polymorphisms (SNPs) are the most frequent DNA sequence variations in the genome. They have been studied extensively in the last decade with various purposes in mind. In this chapter, we will discuss the advantages and disadvantages of using SNPs for human identification and briefly describe the methods that are preferred for SNP typing in forensic genetics. In addition, we will illustrate how SNPs can be used as investigative leads in the police investigation by discussing the use of ancestry informative markers and forensic DNA phenotyping. Modern DNA sequencing technologies (also called next generation sequencing or NGS) have the potential to completely transform forensic genetic investigations as we know them today. Here, we will make a short introduction to NGS and explain how NGS may combine analysis of the traditional forensic genetic markers with analysis of SNPs. This will allow acquisition of more information from the sample materials and open up for new possibilities as well as new challenges.
