The Somerton Man and what may have ailed him. An ethnicity tool called Eurogenes Ad-Mix Utilities was used. 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. By Paul Rincon Science editor, BBC News website. To confirm his wife is the granddaughter of the Somerton Man, a DNA test using hairs from the plaster bust will be completed. See also. This will see if the two DNA results, have the same undefinable DNA percentage. Hair was retrieved from the plaster death bust, and DNA was recovered years ago, though the techniques could not reveal much at the time. [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. To be more specific, the group is aiming to identify any possible relatives, physical characteristics, genetic diseases or ethnicity of the Somerton Man. Figure 19 shows part of the genetic diseases outputs. His shoes were new, his double-breasted jacket was pressed but, oddly, all the labels had been removed from his clothes. All images in the public domain, via … 28, 2019. i123456). Secret love could be hidden in Somerton Man’s DNA On this weekend 70 years ago, a body was discovered on Somerton Beach, sparking one of the nation's most baffling and enduring mysteries. The DNA they tested is from someone who believes they are related to the Somerton Man and that just doesn't stand up without confirmation that the relationship is a fact … Maybe Somerton Man was someone Thomson knew, maybe a friend, but maybe just an acquaintance. DNA results of individuals. National Library of Medicine, May. Mortuary photo of the unknown man found dead on Somerton Beach, south of Adelaide, Australia, in December 1948. The results show that Robin even had a cousin who is a direct descendent of Isham Randolph, who was Thomas Jefferson's grandfather. dbSNP provides only a brief description of the clinical effects. The main topic of the project is human identification using software programming and genetic analysis techniques. In general, a DNA Most SNPs do not effect health of owner. genetic information as a sequence built up with four types of nitrogen bases which 2019]. When a DNA raw data reference file is updated, it will be stored as a kit in GEDmatch database, and be compared with other kits in the public database. On 1 De­cem­ber 1948 at 6:30 am, the po­lice were con­tacted after the body of a man was dis­cov­ered on Somer­ton beach near Glenelg, about 11 kilo­me­tres (6.8 mi) south­west of Ade­laide, South Aus­tralia. In order to satisfy the minimum requirements of GEDmatch, a data recovery work would be required which will be introduced in the next task. 28, 2019. Maybe he raped her in 1946, ... and an initial examination of foreign DNA gave no results. Virtual reality specialist Daniel Voshart conducted a facial reconstruction of the mysterious 'Somerton Man' who was found at Somerton Park Beach, south of Adelaide, on December 1, 1948. Different Strontium level in various samples Figure 5. females. The Somerton Man and what may have ailed him. This tool was provided by GEDmatch and can generate a report of ethnicity proportions to the given DNA kit. Who the Somerton Man is will still be a mystery. 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. Post Comments [9] "Raw Data Technical Details", 23andMe, 2019. The third and fourth methods were to remove the first and last n% of SNPs for each chromosome, where n% is the percentage of SNPs we would like to remove. [1] Bineth, J, "Somerton Man: One of Australia's most baffling cold cases could be a step closer to being solved" This Is About, 13 December 2017. A man known as 'Somerton Man was found dead on SA beach in December 1948 ... 'People have said that possibly Derek married me for my DNA. ... the technique allows for … The risk assessment table are listed below. The number of false negatives and false positives are the mean of 4 sets of data. With the Somerton Man's DNA data extracted from his hair, the project team may be able to conduct several DNA examinations and identify characteristics of the man. On December 1st 1948, a well-dressed male was found dead on Somerton Beach in Adelaide. It is a long shot that that tartan represents the Somerton Man's surname, but hey we need to check this. There is no result strongly support Somerton Man's known physical appearence such as hair colour, teeth structure or eye colour. The Somerton Man’s mtDNA haplogroup .. From Byron Deveson. Byron Deveson, lifted from Cipher Mysteries. In order to provide stronger evidence to prove whether the low quality DNA file's ethnicity report is reliable or not, different degradation algorithms were introduced. ... with the closest matches having roots in the Virginia area. false positives and false negatives test: This page was last modified on 7 November 2019, at 11:00. The project aims to investigate the identification of the Somerton man by means of studying his DNA data provided. Image supplied. He called for the Somerton Man's body to be exhumed. Eurogenes K13 model is selected as the 'calculator' model. Some of the man's hairs became embedded in the mould, pulling the hair out with the roots pointing upwards. 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. He suspects Somerton Man fathered a child and left a generational legacy and that Rachel Egan is the Somerton Man's granddaughter. Secret love could be hidden in Somerton Man’s DNA On this weekend 70 years ago, a body was discovered on Somerton Beach, sparking one of the nation's most baffling and enduring mysteries. Available: https://trove.nla.gov.au/newspaper/article/129897161. In the video above: The NSW woman who murdered her husband, boiled his head and plated him up. The quality of Somerton Man's DNA reference file is lower than expected. This program was also developed using C++. Cipher cracking Final Report/Thesis 2018. 2019]. [14] Chen, J. and Seroka, A. And when there is only half amount of SNPs remaining in the DNA kit, the match results would be totally different and be unreliable. 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. A website called GEDmatch was used for conducting DNA analysis. 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. But the trend are similar. As more SNPs are removed, the amount of false positives and false negatives increases until 50% SNPs are removed. [Accessed: 02- Jun- 2019]. The aim of this task is to have a basic understanding of the DNA reference file and DNA analysis techniques. When there is more than half amount of SNPs being removed, the number of false positives and false negatives reaches maximum of 30 which indicate that the match results of original kits and degraded kits are totally different at these levels. According to both graphs, the number of false positives and false negatives for different DNA samples are not same. This model calculates and gives results of the ethnicity proportion in 13 different global regions as shown in Figure 10, and this mode is primarily for European background people since it provides more sub-continental regions for Europe. But in another case, the highest standard error for first and second region proportions of sample 1 and 2 are 1.32%, 1.41%, 1.33% and 1.03%. 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. Python language was used for development since it is convenient for web development. And false negatives would present kits that are matched with original kit but not with the degraded one. 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. They found that he and his mother belonged to haplogroup H4a1a1a, which is possessed by only 1% of Europeans. These changes shows that the proportion of major ethnicity regions would not change greatly when a complete human DNA file is degraded to a level of 2% SNPs remaining. building and maintaining an organism 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. 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. Available at: https://genealogical-musings.blogspot.com/2017/04/finally-gedmatch-admixture-guide.html [Accessed 29- Oct- 2019]. According to the findings in this task, the project can conclude that it would require a high level quality of DNA which would be at least more than 90% SNPs are available in the DNA reference file to receive a reliable DNA match results. structure. The change of test results will be observed and discussed. 19 January 2016 ... but sometimes gave conflicting results. The first strategy was that for every 10 SNPs, the first n% SNPs were removed where n% is the percentage of SNPs we would like to remove. Where the Somerton Man's body was found. I noted that no one has suggested that there was a match between Robin and SM in that regard. Several risks occurred during the progress. Then when the plaster was poured into the mould, the roots got embedded into the plaster. The details are shown in the table below. These files were then uploaded to GEDmatch and the same ethnicity research was conducted as what has been done on Somerton man's DNA raw data. An unknown man was murdered on the Somerton beach, and the identification of the victim is still a mystery. This “i” format is used internally by 23andMe to identify the unknown SNP and cannot be used in public database. The tomb of the Somerton Man, in Adelaide’s West Terrace cemetery. It is obvious that there is too many empty SNPs in Somerton Man's DNA reference file. The aims of this task is to investigate what results if the DNA match services provide on GEDmatch are conducted on high quality DNA kits, and how the degradation could effect the match results. I do not understand how that could confirm anything virtual or otherwise. Attorney-General Vickie Chapman said on Monday she would give conditional approval for the man's body to be exhumed, in a bid to solve the now more than 70-year-old cold case. The next algorithm performed was the opposite of the first algorithm. a single DNA molecule. Even the DNA kits with all empty SNPs recovered could find a matched DNA result. As an initial test, The University of Adelaide team successfully determined that the Somerton Man's mother belongs to DNA haplogroup H. Sadly, Robin died of prostate cancer in 2009. [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. But the results could take up to a year to process.” I have previously given the reasons why I think that even a very partial DNA sequence should be sufficient to identify relatives of Somerton Man. None of these standard errors exceed 1.5% which can be seen as an acceptable errors. It would surprise me if it had not now … Until then, the Somerton Man will remain as mysterious as he was when his body was discovered nearly 70 years ago. The SNP database the project selected to use was dbSNP which is the largest database for nucleotide variations in the world, and is managed by the National Center for Biotechnology Information (NCBI). These SNPs can be found nearly once in every 1,000 See also. Part 3- The Somerton Man’s Belongings ... Robin’s DNA. National Library of Medicine, May. And I think there is some truth to that.' is finding an intact body and never identifying it like the Somerton man still a thing? When researchers attempted this task, Robin was already deceased hence they had to use a new technique. 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. To be specific, his ethnicity is about 36.21% North Atlantic and 20.44% Baltic. [2] U.S. National Library of Medicine, "What is DNA?",U.S. He was cremated, and so his DNA is unavailable. Picture Credit: News.com.au, Plaster cast made of the Somerton Man. But there is always at least one member attend the meeting with the supervisor. no matter whose body you find you should be able to find some third or fourth cousins on sites like … Through extensive research on the case, Somerton Man has a granddaughter. 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. After more than half century, the identification of the Somerton Man is still unknown. This ID linked to the Clinvar database and allow the user to find a detailed medical report about the disease. ABC journalist and host of Radio National podcast The Somerton Man Mystery, Fiona Ellis-Jones, theorises that the key to the case lies with Joe. As for the genetic disease, 574 diseases were found, but there was no disease found that relates to his known appearance. 2 sample DNA reference files were degraded into 9 files at different levels from 90% to 10% SNPs remaining. The project ordered 2 sets of complete DNA reference data from 23andMe which provide same format as Somerton Man's file. To get the paternal DNA (YDNA) of the man, one needs the hair roots. Spit in a little tube, mail it in, and wait for the results. Published. After years of forensic investigation, Somerton Man's identity remains a mystery (Part 2: DNA, isotopes, and autopsy) 3 June 2015, by Lisa Zyga From the autopsy photos, investigators can determine Picture Credit: News.com.au, Professor Derek Abbott. The recovery works was done by developing multiple programs using C++. The project team collected the clinical significance related to each rsid in Somerton Man's file. No name, no clues, a dead end. mitochondria. The degradation process affected the proportion of each ethnicity region for DNA sample 1, but the change is not much and the first and second regions are still the largest 2 regions in the pie chart. Figure 21 present line graph of the number of false negatives and false positives against degradation levels. Sample DNA reference file 1 contained 613967 SNPs and 96.41% of them were not empty, and DNA reference file 2 has 614009 SNPs and 97.68% of them were available for use. This project only focuses on the analysis of nuclear DNA. The first aim of this task is to investigate the ethnicity of the Somerton Man. There are a lot of theories as to why he was in Australia and who he was but we still don’t have a definitive answer. would pair up (A with T and C with G) ClinVar: public archive of relationships among sequence variation and human phenotype. Abbott also tracked down the Barbour waxed cotton of the period and found packaging variations. The Somerton Man's DNA was selected as input kit of the utility and the ethnicity report was generated. 112, pp.664-665 2013. and multiple nucleotides are placed in To prove the ethnicity report created was reliable, 2 complete DNA files were gained and were degraded to the same level of Somerton Man's DNA which is 2% SNPs remaining in the file. [Online]. There are 4 degradation strategies introduced in task 3, therefore 4 sets of false negatives and false positives are provided for analysis. More links to the Somerton Man’s DNA could emerge any day, further pinning down his family origins. Also, the ethnicity of 2 DNA samples are Asian, but the Somerton Man's ethnicity has higher chance to be European. Several points can be introduced to improve the outcome of the project. 28, 2019. Therefore the top two major ethnicity of the Somerton Man are North Atlantic and Baltic, where these two regions are mostly around Europe. Only a small amount of SNPs in the DNA file are changed could result a significant affect on DNA match results. Firstly, there are only 2 DNA samples in this project for analysis. 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. DNA stores The Somerton Man is an unidentified body from 1948. The site become well known after law enforcement in California use it for the Golden State Killer case and are commonly used by all law enforcement in United States. Only about 2% of 613905 SNPs in the files are available for use. Tamam Shud Case; Further reading. According to the result of task 2 and task 4, the degradation process would have huge effect on the match results of a human DNA data. In general, the recovery work is to replace a fixed amount of empty SNPs which is 2000 SNPs for each chromosome with available SNPs. Moreover, … 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. Comparison between mysterious code and horses’ name Figure 4. The second column chromosome identify which chromosome the SNP belongs to (1st to 22nd chromosome). The degraded files with 10% SNPs remaining have no match results. The project conducts a study on investigating the identification of the victim, Somerton Man, which is one of the most mysterious cases in South Australia until today. The aim of the project is to investigate the identification of the Somerton Man. In February 2018, the University of Adelaide team obtained a high definition analysis of the mitochondrial DNA from the hair sample from Somerton Man. It is important to note that all 5 recovery strategies were all implemented. 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. Average result of heritage data Figure 6. As the graph shown, each region proportion fluctuate at a certain level. Any further attempts to identify the body have been hampered by the embalming formaldehyde having destroyed much of the man’s DNA. Single nucleotide polymorphism (SNP) is a genetic variation But several interesting characteristics were discovered. 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. looks like a spiral [2]. Similar phenomenon can be discovered when comparing ethnicity reports of DNA sample 2. With the support of data mining program, 613905 SNPs were searched in the database and 574 diseases were found. The first major region proportion has reduced 4.64% and the second region proportion has increased for 3.32%. So far, that is what the project can find in regards to the Somerton Man's DNA data. UPDATE: Somerton Man's DNA may be linked to Thomas Jefferson's descendants. But the team is still evaluating demand of using these services. The man in the photograph does bear a resemblance to the Somerton Man, and would've been 48 when the Somerton Man's body was found- an appropriate age, based on autopsy findings. The man was neatly dressed and appeared to be aged in his forties. By degrading several complete DNA files, we can observe how degradation could affect DNA analysis results. So far most work that can operated with the Somerton Man's DNA. With such low portion of available SNP, limited DNA analysis techniques can be conducted on the file. DNA testing has shown that Robin has American relatives. This theory is based on rare genetic similarities between the Somerton Man and Robin, such as the shape of the teeth and the ears. In this task, the project group aims to artificially recover Somerton Man's DNA file to satisfy the basic SNPs amount requirements (2000 SNPs for each chromosome) of GEDmatch's one-to-many tool and find out how many people is related to Somerton Man's DNA kit. Chromosome is an integrated package of DNA molecules. In addition, to investigate the reliability of a low quality DNA data file's ethnicity report, several complete DNA samples was analysed. Column Total cM shows the total centimorgan which is a measure of genetic linkage between the 2 DNA kits. According to the ethnicity reports shown in those figures, the proportion of the largest and second largest ethnicity regions of sample DNA file 1 have changed to 83.13% to 78.66% and 14.82% to 18.14% after degradation process. [Online]. Unfortunately, none of diseases in the results relates or corresponds to Somerton Man's known characteristics. With DNA data that only contains approximate 2% available SNPs, it is nearly impossible to find any possible related DNA kits to Somerton Man. two strands to form a double helix which Members sometimes misunderstand assigned task, but issues were always fixed in the meeting in the following week. differences among people depends on these 1% DNA. [8] “Cryptic Note On Body” The News, June 6, 1949, p. 1 [online]. [Accessed: 03- Jun- 2019]. [6] G. Shaw. Picture Credit: ABC News. The program was developed using C++ language. Unfortunately, there was no DNA kit that matched with Somerton Man's DNA kit found in GEDmatch database. GEDmatch is a website that has an open data personal genomics database and provide tools for DNA and genealogy research.
