Item Evaluation of a Novel Multiplex Ministr System for Analysis of Degraded and Low Copy DNA Samples(2006-05-01) Orcutt, Joseph L.; Arthur Eisenberg; Joseph Warren; John PlanzOrcutt, Joseph L., Evaluation of a Novel Multiplex MiniSTR System for Analysis of Degraded and Low Copy DNA Samples. Masters of Science (Forensic Genetics), May, 2006, 78 pp., 25 tables, 14 figures, bibliography, 20 titles. The goal was to evaluate the performance of a novel miniSTR multiplex system for the analysis of degraded and low quantity DNA samples. Three studies were designed to evaluate this new miniSTR kit: 1. A concordance study to insure that the profiles generated are identical to those with currently used STR kits; 2. A dilution study to identify the sensitivity limits of the multiplex system, and 3. The ability to generate profiles from DNA isolated from skeletal remains which had previously given incomplete profiles using conventional STR kits. The results indicate that the Applied Biosystems new miniSTR multiplex system will provide a valuable tool for forensic scientists to obtain genetic data from challenging casework samples.Item Validation of the Laboratory Information Systems Applications (LISA): Kinship Analysis Module(2008-11-01) Escobedo, IsraelEscobedo, Israel, Validation of the Laboratory Information Systems Applications (LISA): Kinship Analysis Module. Master of Science (Biomedical Sciences), December 2008, 155 pp., 10 tables, 21 figures, references, 34 titles. The Laboratory Information Systems Applications (LISA) is a LIMS system designed for the management and analysis of genetic data from large scale investigations of human identification. The validation study evaluated the pedigree construction and analytical tools of the Kinship Analysis module. The genetic data from old paternity cases was used to construct pedigrees under several scenarios that stimulate situations involving a missing child/parent. Each pedigree was analyzed to obtain a KI that measures the strength of the observed genetic evidence for an association made between a missing/deceased individual and a family reference pedigree to make identification. A common distribution of the number of observations per range of the 1n KI was observed in all scenarios. A concordance and reproducibility study was conducted for eight families using a validated kinship analytical program. LISA has the potential of becoming an efficient tool for human identification despite the limitations of the software.
