Testo completoThe use of genetic marker testing to resolve cases of disputed paternity, is well established. The number and range of systems used depends on the expertise of the laboratory, and for this reason various laboratories offer different systems. Standard testing includes tests in the following genetic marker systems: human leukocyte antigen (tissue) typing; red cell blood groups; and red cell enzyme and serum protein testing. The Provincial Laboratory for Tissue Immunology currently offers a range of 16 genetic marker systems capable of excluding >99% of falsely accused men. Following the discovery DNA polymorphisms, particularly VNTR DNA polymorphisms, and the commercial availability of VNTR DNA probes, PLTI decided to offer this service to our clients. This study was the initial phase in the establishment of a VNTR DNA typing laboratory and covered the determination of inter-and intra-gel accuracy and precision, selection of restriction enzyme/probe combination, and evaluation and comparison of the results of 100 disputed paternity cases tested using both standard and VNTR DNA typing. Of the 100 cases tested, in 33 cases, the putative father was excluded using standard testing. These exclusions were confirmed using VNTR DNA typing, and, furthermore, an additional two exclusions of paternity were shown using only VNTR DNA typing. In another two cases of disputed paternity, the exclusions obtained using standard tests required further confirmation. VNTR DNA typing convincingly excluded both falsely accused putative fathers. The VNTR DNA typing laboratory now functions as an integral part of the disputed paternity service. Due to the cost and time involved in VNTR DNA typing it is reserved at this stage for: those cases which require further confirmation of the results of standard testing; when the probability of paternity is low (<99.7%); or when a specific request is made.

Testo completoShort tandem repeat (STR) analysis is currently the most common method for processing biological forensic evidence. STRs are highly polymorphic and allow for a strong statistical power of discrimination when comparing deoxyribonucleic acid (DNA) samples. Since sample testing and court proceedings occur months, if not years apart, samples must be stored appropriately in the event additional testing is needed. There are generally accepted methods to store DNA extracts long-term; however, one universally recognized method does not exist. The goal of this project was to examine various methods of storage and make recommendations for a universal storage method that maintained DNA integrity over time. Four variables were evaluated: storage buffer, storage temperature, initial storage concentration and the effects of repeated freeze-thaw cycles. DNA quantity was assessed using real-time polymerase chain reaction and DNA quality was evaluated using STR genotyping. Overall, the Tris-EDTA (TE) buffer outperformed nuclease free water as a long-term storage buffer for DNA extracts. Stock tubes stabilized concentration better than single use aliquots when eluted with TE while tube type was not significant when water was the buffer. For samples stored in TE, temperature had no effect on DNA integrity over time, but samples stored in water were largely affected at room temperature. Additionally, the greater the initial DNA concentration, the less likely it was to degrade in water. As a result of this research, DNA extracts from forensic samples should be stored long-term in TE buffer with a minimum concentration of 0.1 ng/μL. When water is the buffer, frozen storage is recommended.

Testo completoForensic DNA profiling is widely used as an identification tool for associating an individual with evidence of a crime. Analysis of a DNA sample involves observation of data in the form of an electropherogram, and subsequently annotating a DNA “profile” from an individual or from the evidence. The profile obtained from the evidence can be compared to reference profiles deposited in a national DNA database, which may include the potential contributor. Following a match, a random match probability is calculated to determine how common that genotype is in the population. This is the probability of obtaining that same DNA profile by sampling from a pool of unrelated individuals. Each state has adopted various laws requiring suspects and/or offenders to submit a DNA sample for the national database (such as California’s law that all who are arrested must provide a DNA sample). These profiles can then be associated with past unsolved crimes, and remain in the database to be searched in the event of future crimes. In the case of database samples, a physical sample of the offender’s DNA must be kept on file in the laboratory indefinitely so that in the event of a database hit, the sample is able to be retested. Current methods are to collect a buccal swab or blood sample, and store the DNA extracts under strict preservation conditions, i.e. cold storage, typically -20° C. With continually increasing number of samples submitted, a burden is placed on crime labs to store these DNA extracts. A solution was required to help control the costs of properly storing the samples. FTA™ paper was created to fulfill the need for inexpensive, low maintenance, long term storage of biological samples, which makes it ideal for use with convicted offender DNA samples. FTA™ paper is a commercially produced, chemically treated paper that allows DNA to be stored at room temperature for years with no costly storage facilities or conditions. Once a sample is required for DNA testing, a small disc is removed and is to be used directly in a PCR reaction. A high quality profile is important for comparing suspect profiles to unknown or database profiles. A single difference between a suspect and evidentiary sample can lead to exclusion. Unfortunately, the DNA profile results yielded from the direct addition have been unfavorable. Thus, most crime laboratories will extract the DNA from the disc, leading to additional time and cost to analyze a reference sample. Many of the profiles from the direct addition of an FTA™ disc result in poor quality profiles, likely due to an increase in PCR inhibitors and high concentrations of DNA. Currently, standardized protocols regarding the recommended locations for removal of a sample disc from a bloodspot on an FTA™ card does not exist. This study aims to validate the optimal location by comparing DNA profiles obtained from discs removed from the center, halfway, and edge locations of a bloodspot from 50 anonymous donors. Optimal punch location was first scored on the number of failed, partial or discordant profiles. Then, profile quality was determined based on peak characteristics of the resulting DNA profiles. The results for all three disc locations were 5.3% failed amplifications, 4.2% partial amplifications, and one case of a discordant profile. Profile quality for the majority of the samples showed a high incidence of stutter and the absence of non-template adenylation. Of the three disc locations, the edge of the blood stain was ideal, due to a presumably lower concentration of DNA and likely more dilute amount of the PCR inhibitor heme. Therefore, based on the results of this study, there is a greater probability of success using a sample from the edge of a blood stain spotted in FTA™ paper than any other location of the FTA™ card.

Testo completoDNA phenotyping is a rapidly developing area of research in forensic biology. Externally visible characteristics (EVCs) can be determined based on genotype data, specifically from single nucleotide polymorphisms (SNPs). These SNPs are chosen based on their association with genes related to the phenotypic expression of interest, with known examples in eye, hair, and skin color traits. DNA phenotyping has forensic importance when unknown biological samples at a crime scene do not result in a criminal database hit; a phenotype profile of the sample can therefore be used to develop investigational leads. IrisPlex, an eye color prediction assay, has previously shown high prediction rates for blue and brown eye color in a European population. The objective of this work was to evaluate its utility in a North American population. We evaluated the six SNPs included in the IrisPlex assay in an admixed population sample collected from a U.S.A. college campus. We used a quantitative method of eye color classification based on (RGB) color components of digital photographs of the eye taken from each study volunteer and placed in one of three eye color categories: brown, intermediate, and blue. Objective color classification was shown to correlate with basic human visual determination making it a feasible option for use in future prediction assay development. In the original IrisPlex study with the Dutch samples, they correct prediction rates achieved were 91.6% for blue eye color and 87.5% for brown eye color. No intermediate eyes were tested. Using these samples and various models, the maximum prediction accuracies of the IrisPlex system achieved was 93% and 33% correct brown and blue eye color predictions, respectively, and 11% for intermediate eye colors. The differences in prediction accuracies is attributed to the genetic differences in allele frequencies within the sample populations tested. Future developments should include incorporation of additional informative SNPs, specifically related to the intermediate eye color, and we recommend the use of a Bayesian approach as a prediction model as likelihood ratios can be determined for reporting purposes.

Testo completo"which a social group or individual thinks is wrong. So the first port of call will be the courts, where we should be able to expect an independent judiciary. However, it is also true that sometimes actions and decisions are taken which, although in themselves not contentious, accumulate along with other legislation to create a highly questionable situation. Note here that the situation becomes questionable: an interpretation of the rules becomes possible which some would simply not agree with. For example, progressive attitudes towards free speech has resulted in the situation being taken advantage of by extreme groups for political ends. There are a number of very specific points which can be made about the use of DNA by society and more especially the construction and use of DNA databases. It is unlikely that anybody would really object to construction of anonymous databases so that we can produce a precise and reliable figure for the probability of finding a DNA profile in the general population by chance alone. What many people do have objections to is the construction of databases of named individuals. Strangely, it would seem that the country that has always been in the van of development of DNA technology is developing a rather poorer reputation for riding roughshod over the rights of its population, the UK. The problems and objections with databases of named individuals start with the practitioners and political will by successive governments. Luckily, there is an outspoken reaction to the UK government’s belief that all uses of DNA are good, but we should be aware that this is not so. Current thinking is that in the future it will be possible to determine facial shape, such as nose type and eye colour, with a simple test. This is put forward as a distinct possibility by the Forensic Science Service, with little regard to the extreme complexity of both the genetics and the environmental input into such things, not to mention plastic surgery. While it was always the belief that rapid turnaround of DNA results would be a good thing, this is only if the techniques are highly controlled. The idea that a hand held machine, as has been suggested, could be taken to a scene of crime and the DNA analysed in situ should fill any self-respecting scientist with horror. It has already been stated that there is a 40% chance of a stain found at a crime scene being linked to a name on the database of named individuals. As databases become larger as well as the number of individuals putting data on the database, so the likelihood of error increases; remember that error in this sense is quite likely to ruin a life. Names get onto databases for perfectly innocent reasons. Two of these are the husband or partner of a rape victim and, which is even more demeaning, the DNA profile of the victim herself. This was admitted in the House of Lords. So why is the British public so lacking in interest or apparently not in the least bit bothered by this staggering lack of feeling for the innocent? There is no mechanism for the removal of a DNA sample from the database after consent has been given. It is of interest here that both the police, forensic scientists and politicians are extremely reluctant to give a sample which can be held on the named database. Why is this? Fear? Fear of what may be done with such intimate information. This includes medical analysis and data which they have no right to access. It would be". In Genetics and DNA Technology: Legal Aspects, 109.
