SNPs in forensic genetics: a review on SNP typing methodologies

Forensic Sci Int. 2005 Nov 25;154(2-3):181-94. doi: 10.1016/j.forsciint.2004.10.020. Epub 2005 Jan 11.


There is an increasing interest in single nucleotide polymorphism (SNP) typing in the forensic field, not only for the usefulness of SNPs for defining Y chromosome or mtDNA haplogroups or for analyzing the geographical origin of samples, but also for the potential applications of autosomal SNPs. The interest of forensic researchers in autosomal SNPs has been attracted due to the potential advantages in paternity testing because of the low mutation rates and specially in the analysis of degraded samples by use of short amplicons. New SNP genotyping methods, chemistries and platforms are continuously being developed and it is often difficult to be keeping up to date and to decide on the best technology options available. This review offers to the reader a state of the art of SNP genotyping technologies with the advantages and disadvantages of the different chemistries and platforms for different forensic requirements.
