Abstract X chromosome STR typing has emerged recently as a powerful tool, complementary to autosomal STR typing, in solving complex forensic and missing person cases. Investigator® Argus X-12 is a commercial product that allows co-amplification of 12 X chromosomal markers belonging to four linkage groups (LGs). In this study, we analyzed by capillary electrophoresis blood samples from 100 females and 102 males from a population of northern Croatia. Statistical analysis included calculation of allele and haplotype frequencies, as well as forensic parameters. The most informative marker for the northern Croatia population was DXS10135 with PIC=0.9211 and a total of 27 alleles. The least polymorphic marker was DXS8378 with 6 alleles. The proportion of...

Genetic and phenotypic variability of iris color in Buenos Aires population
Provedor de dados: 74
Autores: Hohl,Diana María; Bezus,Brenda; Ratowiecki,Julia; Catanesi,Cecilia Inés.
Abstract The aim of this work was to describe the phenotypic and genotypic variability related to iris color for the population of Buenos Aires province (Argentina), and to assess the usefulness of current methods of analysis for this country. We studied five Single Nucleotide Polymorphisms (SNPs) included in the IrisPlex kit, in 118 individuals, and we quantified eye color with Digital Iris Analysis Tool. The markers fit Hardy-Weinberg equilibrium for the whole sample, but not for rs12913832 within the group of brown eyes (LR=8.429; p=0.004). We found a remarkable association of HERC2 rs12913832 GG with blue color (p &lt; 0.01) but the other markers did not show any association with iris color. The results for the Buenos Aires population differ from those...

Impact of a chromosome X STR Decaplex in deficiency paternity cases
Provedor de dados: 74
Autores: Trindade-Filho,Aluisio; Ferreira,Samuel; Oliveira,Silviene F.
Deficiency paternity cases, characterized by the absence of the alleged father, are a challenge for forensic genetics. Here we present four cases with a female child and a deceased alleged father in which the analysis of a set of 21 or 22 autosomal STRs (AS STRs) produced results within a range of doubt when genotyping relatives of the alleged father. Aiming to increase the Paternity Index (PI) and obtain more reliable results, a set of 10 X-linked STR markers, developed by the Spanish and Portuguese Group of the International Society for Forensic Genetics (ISFG), was then added. Statistical analysis substantially shifted the results towards the alleged fatherhood in all four cases, with more dramatic changes when the supposed half-sister and respective...

Haplotype diversity of 17 Y-str loci in an admixed population from the Brazilian Amazon
Provedor de dados: 74
Autores: Francez,Pablo Abdon da Costa; Ramos,Luiz Patrick Vidal; Palha,Teresinha de Jesus Brabo Ferreira; Santos,Sidney Emanuel Batista dos.
The allelic and haplotype frequencies of 17 Y-STR loci most commonly used in forensic testing were estimated in a sample of 138 unrelated healthy males from Macapá, in the northern Amazon region of Brazil. The average gene diversity was 0.6554 ± 0.3315. 134 haplotypes of the 17 loci were observed, 130 of them unique and four present in two individuals each. The haplotype diversity index was 0.9996 + 0.0009, with the most frequent haplogroups being R1b (52.2%), E1b1b (11.6%), J2 (10.1%) and Q (7.2%). Most haplogroups of this population belonged to European male lineages (89.2%), followed by Amerindian (7.2%) and African (3.6%) lineages.

A cost-effective method for rapid identification of the southern muriqui (Brachyteles arachnoids: a contribution for the control of illegal bushmeat trade
Provedor de dados: 81
Autores: Valões Cardoso,M. Luiza; Ferreira,Paula B; Wanderley,Artur M; Torres,Rodrigo A; Talebi Gomes,Mauricio; Teixeira,Rodrigo H. F; Duarte,José M. B; Garcia,José E.
To control illegal wildlife-product trade and protect endangered species of animals, unambiguous identification of the captured specimens is essential. Forensic genetic tools have contributed to identify animal species for conservation purposes promoting accurate results for informing public policies and management of the biodiversity. The southern muriqui (Brachyteles arachnoides) is the largest non-human primate of the Neotropical region and is critically endangered (IUCN Red List of Threatened Species), mainly due to the illegal hunting for bushmeat. In this study, we describe a molecular method using PCR/RFLP to differentiate between bushmeat of southern muriqui and the meat of the domestic animals most commonly consumed in Brazil (Bos taurus, Ovis...

Molecular identification of Atlantic goliath grouper Epinephelus itajara (Lichtenstein, 1822) (Perciformes: Epinephelidae) and related commercial species applying multiplex PCR
Provedor de dados: 83
Autores: Damasceno,Júnio S.; Siccha-Ramirez,Raquel; Oliveira,Claudio; Mendonça,Fernando F.; Lima,Arthur C.; Machado,Leonardo F.; Tosta,Vander C.; Farro,Ana Paula C.; Hostim-Silva,Maurício.
ABSTRACT The Atlantic goliath grouper, Epinephelus itajara , is a critically endangered species, threatened by illegal fishing and the destruction of its habitats. A number of other closely related grouper species found in the western Atlantic are also fished intensively. While some countries apply rigorous legislation, illegal harvesting followed by the falsification of fish products, which impedes the correct identification of the species, is a common practice, allowing the catch to be marketed as a different grouper species. In this case, molecular techniques represent an important tool for the monitoring and regulation of fishery practices, and are essential for the forensic identification of a number of different species. In the present study,...
