Multiplexed Assays for Evaluation of Y-SNP Markers in U.S. Populations

April 1, 2004

Author(s)

Peter Vallone, John Butler

Genetic markers located on the Y chromosome are of increasing importance in human identity testing. In an effort to evaluate the forensic utility of Y chromosome single nucleotide polymorphism (SNP) markers, we constructed several novel multiplex allele

Duplication of DYS19 Flanking Regions in Other Parts of the Y Chromosome

March 25, 2004

Author(s)

John M. Butler, R Schoske

During the testing of alternative primers for the Y chromosome short tandem repeat marker DYS19, a duplicated region of the Y chromosome was discovered. The duplicated sequence is contained within GenBank accession AC006335 and has a high degree of

Y-SNP Typing of Two U.S. Populations Using Allele-Specific Hybridization and Primer Extension

March 17, 2004

Author(s)

Peter Vallone, John Butler

Multiplex analysis of genetic markers has become increasingly important in a number of fields including DNA diagnostics and human identity testing. Two methods for examination of single nucleotide polymorphisms (SNPs) with a potential for a high degree of

High-Throughput Y-STR Typing of U.S. Populations With 27 Regions of the Y Chromosome Using Two Multiplex PCR Assays

January 28, 2004

Author(s)

R Schoske, Peter M. Vallone, Margaret C. Kline, Janette W. Redman, John M. Butler

Two Y-chromosome short tandem repeat (STR) multiplex polymerase chain reaction (PCR) assays were used to generate haplotypes for 19 single copy and 3 multi-copy Y-STRs. A total of 27 PCR products were examined in each sample using the following loci: DYS19

Highly Multiplexed Assays for Measuring Polymorphisms on the Y-Chromosome

October 17, 2003

Author(s)

John M. Butler, R Schoske, Peter Vallone

A multiplex PCR assay capable of amplifying 20 Y chromosome short tandem repeat (STR) markers simultaneously has been developed. These markers include all of the Y STRs that make up the extended haplotype used in Europe (DYS19, DYS385, DYS389I/II, DYS390

The Development of Reduced Size STR Amplicons as Tools for Analysis of Degraded DNA

September 1, 2003

Author(s)

John M. Butler, Y Shen, B. R. McCord

Biotech SRMs Designed for the Rapidly Evolving Forensic DNA and Human Identity Testing Communities

August 1, 2003

Author(s)

Margaret C. Kline, David L. Duewer, John M. Butler

As advances in biotechnology have been applied to human identification, the National Institute of Standards and Technology (NIST) has provided Standard Reference Material (SRM ) to aid the forensic community to assure the quality of their measurements. SRM

Allele Frequencies for 15 Autosomal STIR Loci on U.S. Caucasian, African American, and Hispanic Populations

July 1, 2003

Author(s)

John M. Butler, R Schoske, Peter M. Vallone, Janette W. Redman, Margaret C. Kline

A total of 700 DNA samples from 3 U.S. Populations were examined at 15 different short tandem repeat (STR) markers commonly used is human identity testing. this manuscript simply describes the allele frequencies observed with our samples, which were

NIST Mixed Stain Study #3: DNA Quantitation Accuracy and its Influence on Short Tandem Repeat Multiplex Signal Intensity

May 15, 2003

Author(s)

Margaret C. Kline, David L. Duewer, Janette W. Redman, John M. Butler

The Mixed Stain Study #3 (MSS3) interlaboratory challenge exercise evaluated the 2001 performance of STR multiplex DNA typing systems using a set of seven DNA extracts of designed concentration and composition. This initial report focuses on the linkages

September 10, 2002

Author(s)

John M. Butler, R Schoske, Peter M. Vallone, Margaret C. Kline, A J. Redd, M F. Hammer

A multiplex PCR assay capable of simultaneously amplifying 20 Y-chromosome short tandem repeat (STR) markers has been developed to aid human identity testing and male population studies. These markers include all of the Y STRs that make up the extended
