Abstract
Fields of forensics, transplantation, and paternity rely on human identity testing. Currently, this is accomplished through amplification of microsatellites followed by capillary electrophoresis. An alternative and theoretically better approach uses multiple single-nucleotide polymorphisms located within a small region of DNA, a method we initially developed using HLA-A and called haplotype counting. Herein, we validated seven additional polymorphic loci, sequenced a total of 45 individuals from three of the 1000 Genomes populations (15 from each), and determined the number of haplotypes, heterozygosity, and polymorphic information content for each locus. In addition, we developed a multiplex PCR that amplifies five of these loci simultaneously. Using this strategy with a small cohort of leukemic patients who underwent allogeneic bone marrow transplantation, we first attempted to define a threshold (0.26% recipient) by examining seven patients who tested all donor and did not relapse. Although this initial threshold will need to be confirmed in a larger cohort, we detected increased recipient DNA above this threshold 90 to 145 days earlier than microsatellite positivity, and 127 to 142 days before clinical relapse in four of eight patients (50%). Haplotype counting using these novel loci may be useful for ultrasensitive detection in fields such as bone marrow transplantation, solid organ transplant rejection, patient identification, and forensics.

Abstract
Human identity testing is critical to the fields of forensics, paternity, and hematopoietic stem cell transplantation. Most bone marrow (BM) engraftment testing currently uses microsatellites or short tandem repeats that are resolved by capillary electrophoresis. Single-nucleotide polymorphisms (SNPs) are theoretically a better choice among polymorphic DNA; however, ultrasensitive detection of SNPs using next-generation sequencing is currently not possible because of its inherently high error rate. We circumvent this problem by analyzing blocks of closely spaced SNPs, or haplotypes. As proof-of-principle, we chose the HLA-A locus because it is highly polymorphic and is already genotyped to select proper donors for BM transplant recipients. We aligned common HLA-A alleles and identified a region containing 18 closely spaced SNPs, flanked by nonpolymorphic DNA for primer placement. Analysis of cell line mixtures shows that the assay is accurate and precise, and has a lower limit of detection of approximately 0.01%. The BM from a series of hematopoietic stem cell transplantation patients who tested as all donor by short tandem repeat analysis demonstrated 0% to 1.5% patient DNA. Comprehensive analysis of the human genome using the 1000 Genomes database identified many additional loci that could be used for this purpose. This assay may prove useful to identify hematopoietic stem cell transplantation patients destined to relapse, microchimerism associated with solid organ transplantation, forensic applications, and possibly patient identification.

Abstract
We have previously cloned and identified a novel esophageal cancer related gene 2 (ECRG2; GenBank Accession Number AF268198), which is down-regulated in esophageal squamous cell carcinoma (ESCC) and involved in the induction of the apoptosis in esophageal cancer cell lines. In the present study, we have found a short tandem repeat (STR) polymorphism in the noncoding region of the exon 4 of the ECRG2 gene by using PCR-denaturing high-performance liquid chromatography (DHPLC). Three STR genotypes, TCA3/TCA3, TCA3/TCA4 and TCA4/TCA4 were revealed and confirmed by DNA sequencing analysis. A total of 661 objects including 228 patients with ESCC and 373 normal controls were analyzed to investigate the impact of this ECRG2 STR polymorphism on risk of ESCC in case-control studies. Genotypes were determined in 231 controls and 162 cases from Beijing, which is a low risk area of ESCC, and in 142 controls and 126 cases from Linxian, a well-known high-risk area of ESCC. In both of the Beijing and Linxian population, subjects who carried the TCA3/TCA3 genotype were at an increased risk of ESCC compared to those carrying the TCA4/TCA4 genotype, with the adjusted odds ratios (ORs) being 2.05 [95% confidence interval (CI), 1.02-4.06] for the subjects from Beijing and 4.40 (95% CI, 1.93-10.01) for the subjects from Linxian. Furthermore, comparison of the genotype distributions among other cancer sites might suggest that risk of the ECRG2 STR polymorphism might be specific to the esophagus. These findings indicate for the first time that the ECRG2 STR is a genetic susceptibility factor for ESCC and the TCA3/TCA3 allele might play a role in the development of this cancer.

Abstract
Abstract
Background: Genotyping based on short tandem repeat (STR) regions is widely used in human identification and parentage testing, in gene mapping studies, and as an approach to studies on the etiopathogenesis and diagnosis of hereditary diseases. We wished to study a new analytical approach that uses capillary electrophoresis and multicolor fluorescence in place of slab gel electrophoresis. Methods: We evaluated the efficiency for parentage and forensic purposes of the AmpFLSTR Profiler PlusTM typing kit that is used with the ABI Prism 310 Genetic Analyzer (System-2 STR), and that of a widely used panel of nine STRs analyzed with conventional slab-gel electrophoresis followed by radioactive detection (System-1 STR). System-2 STR, based on automated capillary electrophoresis and automated sizing of the alleles by Genotyper 2.0 software, was used to determine the allele frequency of the nine loci in 157 Caucasian subjects from southern Italy. On the basis of the data obtained, we submitted 40 trios to parentage testing. Results: A higher median probability of paternity attribution and power of exclusion were obtained with System-2 STR vs System-1 STR: respectively, 99.99% and 99.95% (P <0.05) for attribution; and five and four excluding loci (P <0.05) for exclusion. The most informative and highly discriminating loci were D18S51, D21S11, and FGA. The combined probability of matching-by-chance for all nine STRs was 1.36 × 10−12 for System-2 compared with 1.11 × 10−7 obtained with the other system. The internal standard and allelic ladder of the System-2 STR facilitated accurate and precise genotyping; furthermore, System-2 STR and was faster than the conventional System-1 STR. Conclusions: The System-2 STR allows rapid testing with higher probabilities of attribution and a higher power of exclusion than with the comparison method with slab-gel electrophoresis.

Abstract
Applied DNA typing in medico-legal investigations, in criminalistic practice, and in paternity cases often relies on high inclusion and exclusion probabilities. For that reason, the short autosomal tandem repeat locus D8D306 was validated for forensic use and incorporated into a nonoverlapping multiplex reaction with HUMDHFRP2 and HUMCD4: The allele frequencies of D8S306 in four different regions of Germany (n = 1220 alleles) were determined for use in a population database; the allele distributions did not significantly deviate from each other. The hererozygosity of D8S306 is 83%, expected exclusion chance in stain cases is 96% (paternity cases: 69%), the lowest amount of successfully amplified DNA was 30 pg. The alleles are in Hardy-Weinberg equilibrium.
