The project ordered 2 sets of complete DNA reference data from 23andMe which provide same format as Somerton Man's file. [8] “Cryptic Note On Body” The News, June 6, 1949, p. 1 [online]. Then kits with more amount of empty SNPs were replaced with homozygous pairs or random pairs were created, but none of these files could find relative DNA kits in the database. Several points can be introduced to improve the outcome of the project. He was lying back with his head rest­ing against the sea­wall, with his legs ex­tended and his feet crossed. [Blog] genealogical musings. In DNA analysis, only the SNPs with available base pairs can be used and most genetic analysis technique would require a certain amount of available SNPs. Now, a decade later, his wish may be granted. They found that he and his mother belonged to haplogroup H4a1a1a, which is possessed by only 1% of Europeans. His shoes were new, his double-breasted jacket was pressed but, oddly, all the labels had been removed from his clothes. When researchers attempted this task, Robin was already deceased hence they had to use a new technique. The project team collected the clinical significance related to each rsid in Somerton Man's file. is a genetic sequence formed by multiple I noted that no one has suggested that there was a match between Robin and SM in that regard. By doing so, we can investigate his relatives through the process of comparing his DNA to others and figure out whether the analysis result match up with what we know about the man from photos and police reports. There are two prevailing theories regarding the fate of the Somerton Man. The project team degraded each complete DNA sample files into 9 files by removing 10% SNPs, 20% SNPs and then step by step to 90% SNPs. This can be approached by degrading several complete DNA data samples into different levels and conduct sets of genetic test on them. Mysterious code Figure 3. Firstly, there are only 2 DNA samples in this project for analysis. There have been many arguments against H. C. Reynolds being the Somerton Man by people close to the case, but a professor who examined the photo finds the theory plausible. In this task, one-to-many tool will be used again on 2 sample DNA files the project ordered from 23andMe, and the match results shall be recorded. In March 2009 a University of Adelaide team led by Professor Derek Abbott began an attempt to solve the case through cracking the code and proposing to exhume the body to test for DNA. If Egan isn't a match, Abbott hopes the DNA … These SNPs can be found nearly once in every 1,000 [Accessed: 06- Jun- 2019]. The rsid is a unique id used to identify a specific SNP. He had one unsmoked cigarette tucked behind his ear and another more-than-half smoked cigarette nuzzled between his cheek and his coat’s collar. [10] S. Zhang, "The Coming Wave of Murders Solved by Genealogy", The Atlantic, 2019. The risk assessment table are listed below. However, the Thompson/Thomson family have long established heritage in the USA: It would surprise me if it had not now … Average result of heritage data Figure 6. Picture Credit: 9news, H. C. Reynolds Identifcation Card. Unfortunately the website rejects to process the Somerton Man's data to use the one-to-many tool since the file did not meet the minimum requirements of 2000 SNPs for each chromosome. The Somerton Man case, also known as the 'Tamám Shud' case, has baffled police and investigators for more than 70 years. It is a long shot that that tartan represents the Somerton Man's surname, but hey we need to check this. Crime SA News. The bases The ethnicity reports of 2 complete sample DNA files are presented in figure 16 and 17. A tissue and cigarette were found near the body, and a complete DNA profile was compiled from these. This algorithm removed the last n% SNPs for every 10 SNPs, where n% is the percentage of SNPs we would like to remove. DNA, mtDNA, genealogy,mass spectroscopy and nuclear related matters. One-to-many tool is the main service provided by GEDmatch. The format of rsid starts with “rs” and followed by a number (eg. Figure 7: SNPs counting results of Somerton man DNA file. It is important to note that all 5 recovery strategies were all implemented. As more SNPs are removed, the amount of false positives and false negatives increases until 50% SNPs are removed. With such low portion of available SNP, limited DNA analysis techniques can be conducted on the file. 11:46 AM IT'S OFFICIAL: WA border WILL reopen to NSW and Victoria; An unlit cig­a­rette was o… And false negatives would present kits that are matched with original kit but not with the degraded one. Note that traditionally British striped ties slant from "heart to sword," whereas the Somerton Man's tie that he died in slants in the opposite direction which is a convention the Americans started around 1920. The details are shown in the table below. There are $250 budgets assigned to each member in the project, in which is $500 budgets in total for the project. no matter whose body you find you should be able to find some third or fourth cousins on sites like … The Somerton Man cold case has captivated sleuths — both real and amateur — for decades. 28, 2019. National Library of Medicine, May. Just days after Somerton man's discovery, the case was as cold as the body on the slab. To get the paternal DNA (YDNA) of the man, one needs the hair roots. image copyright Thinkstock. He would come to be known simply as the Somerton Man, and has since become the subject of one of the most baffling mysteries … GEDmatch is a website that has an open data personal genomics database and provide tools for DNA and genealogy research. Picture Credit: ABC News. In task 2, the project has conducted DNA match examination on Somerton Man's DNA kit with multiple methods, but there is no match results for the his DNA reference file. Top 30 match kits of sample 1 are shown in figure 20. The diseases names are recorded in disease name column. Moreover, … The proportion of first 2 largest ethnicity regions of each degraded files have been plotted on line graphs. Picture Credit: News.com.au, Professor Derek Abbott. The second goal is to conduct some DNA analysis on the DNA reference file. The first goal of this task is to evaluate the quality of the file including counting the total amount of SNPs and the amount of available (non-empty) SNPs. DNA testing has shown that Robin has American relatives. The format of DNA reference files used in this project are of the same format which is 23andMe company's file, where 23andMe is a company that attended to provide personal genetic information for customers by using advanced genetic analysis techniques and web-based interactive tools. Available: https://www.theatlantic.com/science/archive/2018/05/the-coming-wave-of- murders-solved-by-genealogy/560750/. (2018). As the evidence seems to suggest that Robin was the son of TSM, researchers have attempted to trace Robin’s DNA with the hope that it may show some insights into the heritage of TSM. differences among people depends on these 1% DNA. Available: https://trove.nla.gov.au/newspaper/article/36371152. It is interesting that Clive sees a resemblance to SM in the Scots-Irish actor Stephen Boyd (AKA Millar) because SM’s mtDNA haplogroup is present at significant levels in Ireland. Image supplied. The tomb of the Somerton Man, in Adelaide’s West Terrace cemetery. The last column, genotype, is the column for base pairs of variants (A, T, G, C). As shown in the figure, there are 4 columns in the DNA reference file: rsid, chromosome, position and genotype. Then the Somerton Man's DNA reference file was uploaded to GEDmatch to be used on the one-to-many tool. Therefore the project concludes that when a large amount of SNPs are removed from a set of DNA data, the ethnicity report generated from the DNA data would be influenced, but the results are still acceptable to identify the owner's ethnicity. There is no result strongly support Somerton Man's known physical appearence such as hair colour, teeth structure or eye colour. ), Where the Somerton Man was found. Welcome to the leading, factual blog with a 7 year history of finding new evidence on this Australian Cold Case. A screenshot of the file is shown in figure 6. Part 3- The Somerton Man’s Belongings ... Robin’s DNA. [Online]. Let’s get to 15,000! Once some relatives are identified it is just a relatively straightforward genealogical task to narrow down the identification to a small family group, even a single individual. This project only focuses on the analysis of nuclear DNA. So far, that is what the project can find in regards to the Somerton Man's DNA data. He suspects Somerton Man fathered a child and left a generational legacy and that Rachel Egan is the Somerton Man's granddaughter. With the support of data mining program, 613905 SNPs were searched in the database and 574 diseases were found. He was clean-shaven, well dressed in a suit and no belongings of him that could prove his identity. Other key evidence no longer exists, such as the brown suitcase, which was destroyed in 1986. By degrading several complete DNA files, we can observe how degradation could affect DNA analysis results. Then the DNA match tests would be conducted on the degraded files created in task 3. Note that the top 30 match kits are the kits with largest total centimorgan. Then the false positives for this degraded kit are D and E, and the false negatives are kits M and N. A line graphs of the number of false positives and false negatives against the percentage of SNPs removed will be created to show how degradation process effect the match results. It seems in the announcement we are not talking about DNA from the Somerton Man, we are talking about DNA from a 'Presumed relative of the dead man'. This ID linked to the Clinvar database and allow the user to find a detailed medical report about the disease. The Somerton Man’s mtDNA haplogroup .. From Byron Deveson. [Online]. Byron Deveson. DNA results of individuals. The problem is, the fact that it has been over 70 years since the death of the Somerton Man means that anyone involved with the murder and cover-up, as well as any real witnesses, are probably dead. However, error bars or standard errors of each region become larger, as more SNPs are removed, which indicate that as more SNPs being removed, the proportions presented in ethnicity reports become less accurate. DNA is a sequence of molecule consisting 4 chemical bases namely Adenine, Guanine, Cytosine, and Thymine that carries the all the information of living things. [16] Inside Story, presented by Stuart Littlemore, ABC TV, screened at 8 pm, Thursday, 24th August, 1978, Task 1: Testing with Somerton Man’s DNA reference file, Appendix A: Codes and tables used in the project, https://www.abc.net.au/news/2017-12-14/somerton-man-cold-case-could-be-, https://ghr.nlm.nih.gov/primer/basics/dna, https://ghr.nlm.nih.gov/primer/basics/chromosome, https://ghr.nlm.nih.gov/primer/basics/howmanychromosomes, https://ghr.nlm.nih.gov/primer/genomicresearch/snp, https://trove.nla.gov.au/newspaper/article/129897161, https://trove.nla.gov.au/newspaper/article/36371152, https://customercare.23andme.com/hc/en-us/articles/115004459928-Raw-Data-, https://www.theatlantic.com/science/archive/2018/05/the-coming-wave-of-, https://www.ncbi.nlm.nih.gov/books/NBK44469/, https://genealogical-musings.blogspot.com/2017/04/finally-gedmatch-admixture-guide.html, https://www.eleceng.adelaide.edu.au/personal/dabbott/wiki/index.php/Final_Report/Thesis_2018, https://docs.google.com/spreadsheets/d/1Oz6P5-SVEJciPX1TciGe-zoqA5JtOGIMG7nh-rCOj0c/edit#gid=804264822, https://www.eleceng.adelaide.edu.au/personal/dabbott/wiki/index.php?title=Final_Report/Thesis_2019&oldid=22126. The remains of a 23 year-old man, who was killed by a blow to the face, were discovered to be at least 9,000 years old. The next algorithm performed was the opposite of the first algorithm. K13_population_averages. The project provides a DNA reference file of the Somerton Man which is a corrupted DNA data. This will see if the two DNA results, have the same undefinable DNA percentage. DNA from the bust. nucleotides on average in a person's DNA. and multiple nucleotides are placed in dbSNP provides only a brief description of the clinical effects. It is obvious that there is too many empty SNPs in Somerton Man's DNA reference file. More details are linked to another database called ClinVar which is a freely accessible, public database that provide medical reports of the relationships among human variants and phenotypes [12]. Cold War spy theories abound around the Somerton Man, particularly because his clothing had the labels cut out, but Renee points out that tens of thousands of migrants arrived in SA in the 2-3 years surrounding the man’s death, and many of them removed the labels from their clothing because they were second-hand and had someone else’s name written in them. base pairs [2]. [Accessed: 02- Jun- 2019]. Somerton man Figure 2. An extra file which contains only the SNPs with same rsids in Somerton Man's DNA file was created and was named as degraded_DNA for each set of complete DNA sample data. DNA can't lie. Several simple recovery algorithms were implemented. By Paul Rincon Science editor, BBC News website. The first aim of this task is to investigate the ethnicity of the Somerton Man. Prof. Jeremy Austin of the University of Adelaide, discusses how DNA will help identification. Unfortunately, the DNA data was corrupted and has a high drop rate, therefore the project team was required to use different strategies and techniques to recover and analyse the DNA, then try to find out any possible characteristics of the Somerton Man. ... Roma Egan, was subtracted from the DNA … To be more sure about that would require exhumation of his corpse and either genetic testing of any intact tissue or chemical analysis of dental enamel, which can reveal where someone lived when their teeth … [online] Available at: https://ghr.nlm.nih.gov/primer/basics/chromosome [Accessed 2 Jun. In this project, the DNA data analysis would only focus on autosomes. Abbott also tracked down the Barbour waxed cotton of the period and found packaging variations. There is another special format of rsid that starts with “i” and followed by a number (eg. National Library of Medicine, May. [online] Available at: https://www.abc.net.au/news/2017-12-14/somerton-man-cold-case-could-be- one-step-closer-to-solved/9245512 [Accessed 1 Jun. The program extracted every non-empty SNP in Somerton Man's DNA reference file. Both DNA samples were successfully found their matched DNA kits in the database. In modern society, human identification techniques is useful in multiple aspects, such as criminal investigation or seeking relatives. Sample 1 have 8182 match kits and there are 5968 DNA files are found related to the sample 2. Post Comments 22 pairs are called autosomes which are common for both In February 2018, the University of Adelaide team obtained a high definition analysis of the mitochondrial DNA from the hair sample from Somerton Man. [Accessed: 04- Jun- 2019]. According to the population averages table[15] for Eurogenes K13 model provided by the developer Davidski (Polako), both Baltic and North Atlantic regions are in Europe. The 23 doubts that surround the Somerton Man Case. I do not understand how that could confirm anything virtual or otherwise. are adenine (A), guanine (G), cytosine (C), and thymine (T) [2].
