This paper describes a newly devised autosomal short tandem repeat (STR) multiplex polymerase chain reaction (PCR) systems for 17 autosomal loci (D1S1656, D2S441, D3S1358, D3S3045, D6S477, D7S3048, D8S1132, D10S1435, D10S1248, D11S2368, D13S325, D14S608, D15S659, D17S1290, D18S535, D19S253 and D22-GATA198B05) and Amelogenin. Primers for the loci were designed and optimized so that all of the am...

Short tandem repeats (STRs) or microsatellites are well-known sequence elements that may change the spacing between transcription factor binding sites (TFBSs) in promoter regions by expansion or contraction of repetitive units. Some of these mutations have the potential to contribute to phenotypic diversity by altering patterns of gene expression. To explore how repetitive sequence motifs withi...

In the past 5 years, there has been a substantial increase in the use of Y-short tandem repeat loci (Y-STRs) in forensic laboratories, especially in cases where typing autosomal STRs has met with limited success. The AmpFlSTR Yfiler PCR amplification kit simultaneously amplifies 17 Y-STR loci including the loci in the "European minimal haplotype" (DYS19, DYS385a/b, DYS389I, DYS389II, DYS390, DY...

PURPOSE Cross-contamination of cell lines is a serious but often unrecognized problem. We describe the authentication of a panel of transitional cell carcinoma cell lines using the short tandem repeat profiling technique to detect cross-contamination. MATERIALS AND METHODS Genomic DNA was isolated from UM-UC-1, UM-UC-2, UM-UC-3 (ATCC), UM-UC-6, UM-UC-9, UM-UC-10, UM-UC-11, UM-UC-13, UM-UC-14,...

A multiplex polymerase chain reaction (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 haplotype" used in Europe (DYS19, DYS385, DYS389I/II, DYS390, DYS391, DYS392, DYS393, and YCAII) plus additional po...

Background Late-Onset Alzheimer’s Disease (LOAD) is characterized by genetic heterogeneity and there no single model explaining the mode of inheritance. Short tandem repeats (STRs), which are hyper-mutable sequences in human genome could explain some missing heritability LOAD. STRs involved several neuro-degenerative disorders. We systematically evaluated impact 31 disease-associated on neuropa...

Over the past several decades, the forensic and population genetic communities have increasingly leveraged short tandem repeats (STRs) for a variety of applications. The advent of next-generation sequencing technologies and STR-specific bioninformatic tools has enabled the profiling of hundreds of thousands of STRs across the genome. Nonetheless, these genotypes remain error-prone, hindering th...

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, DYS385 a/b, DYS388, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS426, DYS437, DYS438, DYS439, DYS447, DYS448, DYS450, DYS456, DYS458, DYS...

The analysis of short tandem repeat (STR) DNA sequences is of fundamental importance to forensic science because they have become the recognized standard in constructing national public databases. Consequently, considerable effort has been expended in developing multiplexed (one tube) reactions that analyze several loci in combination. The implementation of STRs in casework cannot take place wi...

OBJECTIVE G-Banding followed by standard chromosome analysis is routinely used for prenatal detection of chromosomal abnormalities. In recent years, molecular cytogenetic techniques have been developed for rapid diagnosis of chromosomal abnormalities. Among these methods Quantitative Florescence Polymerase Chain Reaction (QF-PCR) has been widely used for this purpose. Heterozygosity of short ta...
