Chávez-Briones MDL, Jaramillo-Rangel G, Ancer-Arellano A, Ancer-Rodríguez J, Ortega-Martínez M. Identification of the Remains of an Adult Using DNA from Their Deciduous Teeth as a Reference Sample. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1702. [PMID: 37893420 PMCID: PMC10608540 DOI: 10.3390/medicina59101702] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 08/30/2023] [Accepted: 09/20/2023] [Indexed: 10/29/2023]
Abstract
In many forensic cases, the identification of human remains is performed by comparing their genetic profile with profiles from reference samples of relatives, usually the parents. Here, we report, for the first time, the identification of the remains of an adult using DNA from the person's deciduous teeth as a reference sample. Fragments of a skeletonized and burned body were found, and a short tandem repeat (STR) profile was obtained. A woman looking for her missing son went to the authorities. When the DNA profile of the woman was compared to a database, a positive match suggested a first-degree kinship with the person to whom the remains belonged. The woman had kept three deciduous molars from her son for more than thirty years. DNA typing of dental pulp was performed. The genetic profiles obtained from the molars and those from the remains coincided in all alleles. The random match probability was 1 in 2.70 × 1021. Thus, the remains were fully identified. In the routine identification of human remains, ambiguous STR results may occur due to the presence of null alleles or other mutational events. In addition, erroneous results can be produced by false matches with close family members or even with people who are completely unrelated to the victim, such that, in some cases, a probability of paternity greater than 99.99% does not necessarily indicate biological paternity. Whenever possible, it is preferable to use reference samples from the putative victim as a source of DNA for identification.

AGE (DORDRECHT, NETHERLANDS) 2015; 37:95.

Abstract
Life span is a complex and multifactorial trait, which is shaped by genetic, epigenetic, environmental, and stochastic factors. The possibility that highly hypervariable short tandem repeats (STRs) associated with longevity has been largely explored by comparing the genotypic pools of long lived and younger individuals, but results so far have been contradictory. In view of these contradictory findings, the present study aims to investigate whether HUMTHO1 and HUMCSF1PO STRs, previously associated with longevity, exert a role as a modulator of life expectancy, as well as to assess the extent to which other autosomal STR markers are associated with human longevity in population from northern Spain. To that end, 21 autosomal microsatellite markers have been studied in 304 nonagenarian individuals (more than 90 years old) and 516 younger controls of European descent. Our results do not confirm the association found in previous studies between longevity and THO1 and CSF1PO loci. However, significant association between longevity and autosomal STR markers D12S391, D22S1045, and DS441 was observed. Even more, when we compared allelic frequency distribution of the 21 STR markers between cases and controls, we found that 6 out of the 21 STRs studied showed different allelic frequencies, thus suggesting that the genomic portrait of the human longevity is far complex and probably shaped by a high number of genomic loci.

Abstract
The molecular origin of DNA mutations and the mutation rates were analyzed at 14 short tandem repeat (STR) loci with samples from trio cases derived from 10 different German population samples. STR loci comprised of D2S1360, D3S1744, D4S2366, D5S2500, D6S474, D7S1517, D8S1132, D10S2325, D12S391, D18S51, D19S246, D20S480, D21S226, and D22S689. In a total of 488 meioses, 16 isolated genetic inconsistencies in 8 different STRs were observed, whereas no mutations were found at the other loci. The data of five mutations suggested the presence of silent or null alleles due to sequence variation in primer binding site. This could be confirmed for four suspected cases by the use of alternative primer sets and by DNA sequence analyses. Furthermore, this study revealed nine new allelic variants at five different loci.

Abstract
The D7S1517, D3S1744, D12S391, D2S1360, D6S474, D8S1132, D5S2500, D10S2325 and D4S236613 are STR loci potentially useful for forensic purposes whose analysis has recently become facilitated by availability of a commercial kit. The purpose of the study was to evaluate the usefulness of these loci for forensic identification in a population of Central Poland. The distribution of alleles of the nine STRs was determined in sample of 353 unrelated individuals born in Central Poland and indices of forensic informativeness were calculated. The studied loci were highly informative and did not show departures from Hardy-Weinberg equilibrium. For the loci located on the same chromosomes (D2S1360, D3S1744 D4S2366, D5S2500, D7S1517, D8S1132, D12S391) as other loci commonly used for identification purposes (TPOX, D2S1338, D3S1358, FGA, D5S818, D7S820, D8S1179 and D12S391) appropriate pairwise analysis of linkage disequilibrium was performed. In all cases no statistically significant deviation from independence was found. We conclude that the studied STRs are informative and, when necessary, can be used to extend the results obtained with other STRs commonly analyzed for identification purposes, in particular the CODIS set.

Abstract
The incorporation of reference DNA is crucial to the validation of any DNA typing protocol. This paper aims to provide a panel of reference DNAs for actual forensic profiling strategies, i.e. autosomal and gonosomal STR typing as well as mtDNA sequencing. We have characterised three human lymphoid cell lines, GM9947, GM9948 and GM3657, and considered 58 autosomal and gonosomal microsatellites as well as the mitochondrial control region sequence. Well-established markers and STRs recently developed for forensic use were involved. K562 DNA samples which we purchased from two different suppliers were also analysed. They revealed conflicting results with regard to the ChrX STR marker genotype. Hence, we suggest that K562 is no longer used for the calibration of profiling techniques. Our investigation establishes a panel of one female and two male DNA samples as an STR allelic ladder calibration tool and offers information on six alleles of each autosome (AS) marker, three alleles of each X chromosome (ChrX) marker and two alleles of each ChrY marker. In addition, sequences of the mitochondrial control region of the three DNAs are communicated in order to provide sequencing quality control.

Abstract
We analyzed the polymorphic structure of the short tandem repeats (STR) (RRGG) locus D18S555 by DNA sequencing, and examined the distribution of alleles in DNA samples from Japanese and Chinese individuals. DNA sequence analysis showed that the alleles at this locus consisted of deletions or insertions of (gaaagaaagaat), (ggaa), (ggaaggaaggag), (ggaaggagggaaggaaggag), (gggaggaa), and (ggga) 5, with each allele having its own DNA sequence. Analysis of 200 unrelated Japanese and 169 unrelated Chinese subjects identified 11 alleles, of which alleles 4, 6, and 13 occurred with a high frequency. There was no difference in allele frequency between the two ethnic groups. These results indicate that the genotyping of D18S555 alleles requires no sequence analysis, and making the locus applicable to forensic identity.
