Abstract:
The forensic relevance of Y-STR analysis is well understood and widely documented. In this report, the authors have described twounusual multi-allelic patterns in Y-STR profiles of individualsobserved during forensic examination.The first is a case of a bi-allelic pattern at the locus DYS391observed in a father/son duo in a paternity dispute. The second case is of a tri-allelic pattern at the locus DYF387S1a/b observed in the Y-STR profile of a suspected perpetrator in a case of sexual assault.In both cases, the individuals belong to theHimalayan stateof Sikkim in Northeast India, and this is

Abstract:
This study measures the similarity of the short tandem repeat (STR) profile of human DNA. The similarity measurement had been done to the STR value of the allele loci in DNA profile between the query’s DNA to the reference’s DNA profile. The measurements were conducted on 27 DNA profile loci including the Y chromosome loci (YSTR). The YSTR loci were used as the main comparison of similarity measurements to determine the biological kinship relationship between the query DNA profile and the alleged male biological family. To measure the similarity of two STR values that have shifted due to sever

Objectives To assess the efficacy of Y-chromosome mini-STR-based next-generation sequencing (NGS) for non-invasive prenatal paternity testing (NIPPT). Methods DNA was extracted from the plasma of 24 pregnant women, and cell-free fetal DNA (cffDNA) haplotyping was performed at 12 Y-chromosome mini-STR loci using the Illumina NextSeq 500 system. The cffDNA haplotype was validated by the paternal haplotype. Subsequentlly, the paternity testing parameters were attributed to each case quantitatively.

Abstract:
This case study focuses on identifying a deceased person by establishing paternity and sibship relationships with alleged relatives through unique sharing of alleles. Bone and blood samples from the deceased were provided, along with reference blood samples from an alleged son and an alleged brother. DNA extracted from these samples was quantified, amplified, and analysed using an 8-capillary array DNA analyzer. By an extremely rare coincidence, each amplified autosomal locus in the DNA profiles from both the alleged son and the alleged brother shared at least one allele with the corresponding

Microsatellites are widely applied in population and forensic genetics, wildlife studies and parentage testing in animal breeding, among others, and recently, high-throughput sequencing technologies have greatly facilitated the identification of microsatellite markers. In this study the genomic data of Cervus elaphus (CerEla1.0) was exploited, in order to identify microsatellite loci along the red deer genome and for designing the cognate primers. The bioinformatics pipeline identified 982,433 microsatellite motifs genome-wide, assorted along the chromosomes, from which 45,711 loci mapped to t

Abstract:
Rapidly mutating Y-chromosomal short tandem repeats (RM Y STRs) with mutation rates ≥ 10−2 per locus per generation are valuable for differentiating amongst male paternal relatives where standard Y STRs with mutation rates of ≤10−3 per locus per generation may not. Although the 13 RM Y STRs commonly found in commercial assays provide higher levels of paternal lineage differentiation than conventional Y STRs, there are many male paternal relatives that still cannot be differentiated. This can be improved by increasing the number of Y STRs or choosing those with high mutation rates. We present a

In this work, we report a rare allele 29 at locus D2S1338, established during routine forensic practice in a case of first-degree kinship (parenthood). This rare allele variant 29 at locus D2S1338, to the best of our knowledge, is reported for the first time for the Bulgarian population. So far it has not been registered in studies of allele frequencies in the same locus for 20 population groups in Europe and Asia. The presentation of similar genotyping findings relating to rare/unexpected population genetic variation is very important for the examination and documentation of such anomalies. T

Abstract:
The application of Y-chromosome analysis is expanding in fields such as forensic science and genealogy. By researching the potential polymorphisms this chromosome can present, we can further our ability to assess DNA profiles for these disciplines to avoid erroneous exclusions of paternal linkage, wrongful convictions based on forensic evidence, and other misinformed genetic conclusions. The conservation of Y-haplotypes during transmission occurs due to a relative lack of genetic recombination events in the inheritance of the Y-chromosome [1]. However, random mutation events can occur in a pa
