Study of Y chromosome markers with forensic relevance in Lisbon immigrants from African countries Allelic variants study
Due to the haploid nature of the human male determinant chromosome, Y chromosome Short Tandem Repeats (Y-STRs) are interesting genetic markers for the identification of potential suspects in certain forensic investigations. Furthermore, being a haploid chromosome, the presence of more than one fragment size in Y-STR analysis is often indicative of a mixture of male DNA. Certain events during DNA replication may lead to the appearance of allelic variants in certain markers that could result in duplications, microvariants or null alleles.

Standardization in forensic genetics A multi-faceted challenge in Poland
Extremely dynamic development of forensic genetics requires cooperation of the professional bodies and institutions in order to make the best use of technological progress for the public good. The need for the high quality of DNA testing for justice and law enforcement in Poland forces the necessity of standardization in this area based on norms and legal Polish as well as European requirements. Among them the most crucial is the implementation of PN-EN ISO/IEC 17025 standard and the fulfillment of the requirements of the DAB-10 (PCA) document.

Estimation of genotyping errors of str markers in dogs and wolves
This article will discuss the estimation of genotyping errors for Mini-DogFiler panel A and B in group of wolfs (n  = 39) where the source material for DNA isolation were faeces and control group of dogs (n = 170), represented by Czechoslovakian wolfdog breed (CSW), where DNA was obtained from buccal swabs.DNA samples isolated from buccal swabs had a very low frequency of genotyping error estimated as me an error rate per allele (ea = 0.09 %), mean error per locus (el = 0.18 %) and error rate per multilocus genotype (eobs = 2.17 %).

Internal Validation of GlobalFilerTM Kit Using Reduced Reaction Volume
For approximately two decades, Microsatellites or Short Tandem Repeat (STR) markers have been the backbone for human identification testing in the forensic field. The expansion of STR multiplex kits can improve global sharing of STR profiles, rapid DNA typing, and DNA typing using high throughput sequencing Flores et al. (2014). GlobalFilerTM kit is highly sensitive and has extremely high power of discrimination. An internal validation of GlobalFiler ™ Kit was carried out to test the robustness of this kit through a range of internal validation studies including half volume reaction, reproducibility, sensitivity, specifi...

A study of old Serbian skeletal remains using ForenSeq DNA Signature kit
In this study Illumina ForenSeq DNA Signature Prep kit was tested to determine if MPS offers a more comprehensive evaluation of degraded samples than the traditional fragment analysis/capillary electrophoresis based method (Athey, 2006). The use of MPS could reduce th e analysis time and augment the identification of human remains. In this context we aimed to analyse bone/tooth samples using ForenSeq DNA Signature kit.

A study of skeletal remains using GlobalFiler
DNA analysis from human remains is of immense relevance in missing persons identification and disaster victim identification (DVI). DNA degrades gradually in hard tissues, such as bones and teeth and remains somewhat safe from the effects of high temperature, humidity, pH, geochemical properties of the soil, and microorganisms. . The GlobalFiler kit simultaneously amplifies and detects 21 autosomal loci including CODIS extended set of STR loci. The kits was designed to combine all 21 autosomal STR loci along with a novel male speci?c Y insertion/deletion marker the sex-determining marker, amelogenin. (Source: Forensic Sc...
