Roccapelago (MO) is a small village located in the Northern Central Apennines, with a population of 31 inhabitants (2014). In 2010, more than 400 individuals dated between the end of the 16th and the 18th century, many of which partially mummified, were discovered in the crypt of the church. This small village, because of its geographical location and surrounding environment, seems to possess the characteristics of a genetic isolate, useful for population genetics and genealogical analyses. Thus, a diachronic study of DNA aimed at investigating the structure and dynamics of the population of Roccapelago over the about 4 centuries, was conducted by analyzing ancient and modern inhabitants of the village. The 14 modern samples were selected by considering both the founder surnames of the village, identified thanks to the study of parish registers, and the grandparent’s criterion. From 25 ancient mummies, morphologically assigned to male individuals, the petrous bone, that harbors high DNA amounts, was selected for the DNA extraction. The quantification and qualitative assessment of total human male DNA were evaluated by a real-time PCR assay using the Quantifiler Trio DNA Quantification Kit and multiplex PCR of 27 Y-chromosome short tandem repeat (Y-STR) markers included in the Yfiler Plus PCR Amplification Kit, with seven rapidly mutating Y-STR loci for improving discrimination of male lineages, was performed to genotype the samples. Y-STRs were analyzed according to the criteria of ancient DNA (aDNA) analysis to ensure that authentic DNA typing results were obtained from these ancient samples. The molecular analysis showed the usefulness of the Y chromosome to identify historically relevant remains and discover patterns of relatedness in communities moving from anthropology to genetic genealogy and forensics.

Hundred unrelated father-son buccal swab sample pairs collected from consented Tanzanian population were examined to establish mutation rates using 17 Y-STRs loci DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385a, DYS385b, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635, and Y-GATA-H4 of the AmpFlSTRYfiler kit used in forensics and paternity testing. Prior to 17 Y-STRs analysis, father-son pair biological relationships were confirmed using 15 autosomal STRs markers and found to be paternally related. A total of four single repeat mutational events were observed between father and sons. Two mutations resulted in the gain of a repeat and the other two resulted in a loss of a repeat in the son. All observed mutations occurred at tetranucleotide loci DYS389II, DYS385a, and DYS385b. The locus specific mutation rate varied between 0 and 1.176 x10−3 and the average mutation rate of 17Y-STRs loci in the present study was 2.353x10−3 (6.41x10−4 - 6.013x10−3) at 95% CI. Furthermore the mean fathers’ age with at least one mutation at son’s birth was 32 years with standard error of 2.387 while the average age of all fathers without mutation in a sampled population at son’s birth was 26.781 years with standard error of 0.609. The results shows that fathers’ age at son’s birth may have an effect on Y-STRs mutation rate analysis, though this age difference was statistically not significant using unpaired samples t-test (p = 0.05). As a consequence of observed mutation rates in this study, the precise and reliable understanding of mutation rate at Y-chromosome STR loci is necessary for a correct evaluation and interpretation of DNA typing results in forensics and paternity testing involving males. The criterion for exclusion in paternity testing should be defined, so that an exclusion from paternity has to be based on exclusion constellations at a minimum of two 17 Y-STRs loci.

Introduction: Madurella mycetomatis is the major causative agent of eumycetoma, a neglected tropical infection characterized by painless subcutaneous lesions, inflammation and grains draining from multiple sinuses. To study the epidemiology of mycetoma, a robust discriminatory typing technique is needed. We describe the use of a Short Tandem Repeats assay (MmySTR) for genotyping of M. mycetomatis isolates predominantly from Sudan. Methods: Eleven microsatellite markers (3 dinucleotides, 4 trinucleotide repeats and 4 tetranucleotide repeats) were selected from the M. mycetomatis MM55 genome using the Tandem Repeats Finder software. PCR amplification primers were designed for each microsatellite marker using primer3 software and amplified in a multicolor multiplex PCR approach. To establish the extent of genetic variation within the population, a collection of 120 clinical isolates from different regions was genotyped with this assay. Results: The 11 selected MmySTR markers showed a large genotypic heterogeneity. From a collection of 120 isolates, 108 different genotypes were obtained. The Simpsons’ diversity index (D) value for individual markers ranged from 0.081-0.881, the combined panel displayed an overall D value of 0.997. The MmySTR assay demonstrated high stability, reproducibility and specificity. Conclusion: The MmySTR assay is a promising new typing technique that can be used to genotype isolates of M. mycetomatis. Apart from the possible contribution of host factors, the genetic diversity observed among this group of isolates might contribute to the different clinical manifestations of mycetoma. We recommend the MmySTR assay to be used to establish a global reference database for future study of M. mycetomatis isolates.

PENENTUAN SIMILARITAS DAN VARIABILITAS GENETIK PADA KELUARGA ETNIS JAWA DAN ARAB DENGAN DNA FINGERPRINT DI MALANG, JAWA TIMUR, INDONESIA ABSTRAKLebih dari sepertiga genom manusia terdiri dari urutan daerah berulang (Repeat area) yang terdiri dari Minisatellite atau Variant Number Of Tandem Repeats (VNTR) dan Microsatellite atau Short Tandem Repeat (STR). STR sebagai daerah berulang dengan rentang alel yang pendek sering digunakan untuk tes paternitas, penelitian penyakit genetik dalam bidang kesehatan, arkeologi molekular, maupun kasus kriminalitas dalam bidang forensic. Tujuan dari penelitian ini adalah untuk mengidentifikasi DNA Fingerprint pada etnis Jawa – Arab dengan menentukan similaritas dan variabilitas genetiknya. Bahan dan metode yang digunakan untuk mengerjakan adalah menggunakan sel darah putih manusia yang berasal dari tiga generasi dalam tiga keluarga yang terdiri dari : (1) Nenek – Ibu, Ayah – anak perempuan, (2) Kakek – Ibu, Ayah – Anak perempuan, (3) Kakek, Nenek – Ibu, Ayah – Anak laki-laki. Isolasi DNA pada tiap sampel diperoleh dengan salting out, selanjutnya Amplifikasi PCR dengan menggunakan 13 CODIS yang meliputi TPOX, D3S1358, FGA, D5S818, CSF1PO, D7S820, D8S1179, TH01, VWA, D13S317, D16S539, D18S51, D21S11 dan amelogenin yang dapat dilihat melalui hasil elektroforesis gel poliakrilamid 8% dengan Chemidoc Gel Imaging. Analisis profil pita pada tiap individu untuk menentukan similaritas dan variabilitas genetik serta pola alel dengan menggunakan software Quantity One. Variasi pola pita DNA dianalisis dengan menggunakan program software GENEPOP package versi 4.2 yang akan didapat frekuensi alel, heterozigositas, dan migrasi alel. Berdasarkan identifikasi yang dilakukan diperoleh bahwa nilai heterozigositas pada populasi III (93.8461%) memiliki nilai heterozigositas lebih tinggi dibandingkan dengan populasi I (88.4615%) dan II (76.9230%) dan telah terjadi migrasi alel 0.341373%.  Adanya persentase migrasi alel tersebut meskipun kecil menunjukkan telah terjadi Breeding diantara populasi Jawa dengan populasi Arab sehingga meningkatkan rata-rata nilai heterozigositas pada tiap populasi. Pola alel heterozigot dengan berdasarkan nilai heterozigositas, jumlah alel pada D21S11, VWA dan THO1 dapat direkomendasikan sebagai penanda molekular untuk identifikasi variasi genetik.Kata kunci: Etnis Jawa–Arab, DNA Fingerprint, 13 CODIS DETERMINING THE GENETIC SIMILARITIES AND VARIABILITY OF JAVANESE AND ARAB ETHNIC FAMILIES WITH DNA FINGERPRINT IN MALANG EAST JAVA INDONESIAABSTRACTMore than one-third of human genome consists of repetitive sequence region (Repeat Area) which consist of Minisatellite or Variant Number Of Tandem Repeats (VNTR) and Microsatellite or Short Tandem Repeat (STR).
