Abstract:
DNA profiling with sets of short tandem repeat (STR) markers is the most popular method for identifying human DNA in forensics. Identification by STR typing might fail when DNA is degraded or is present in low amounts, such as in disaster victim identification (DVI) samples. In such cases, more information might be obtained by using additional markers such as single nucleotide polymorphisms (SNPs). Multiplex PCR and microarray are convenient techniques to analyze SNP markers. We used an AccuID(TM) Chip, SNP-based DNA chip manufactured by DNA Link Corporation, to confirm genetic relationship between two human bone samples that had been buried for more than 50 years and blood samples from the alleged descendants of the sources of the bone fragments. The chip combines an Affymetrix resequencing array with a multiplex PCR technology and can genotype hundreds of SNP markers in a single experiment. Genotyping the two bone samples yielded 90.5 and 77 SNP markers. The commonly genotyped markers (61 and 47 SNP loci) in each bone-family pair provided high paternity indices to support the genetic relationships in both cases.
