[Universal Panel of Insertion/Deletion Polymorphisms and Biochip-Based Kit ChipID106 for Genetic Personal Identification].

A panel of 106 insertion/deletion (InDel) polymorphisms and a method of their genotyping on biochips were proposed as a new approach to genetic personal identification. Short lengths and low mutation rates are basic properties of InDel markers, which thus have significant advantages over short tandem repeats (STRs) widely used in forensics. The allele frequency distributions of all known InDel polymorphisms were studied in the five largest world populations (European, East Asian, South Asian, African, and American).

[A Biochip for Genotyping Polymorphisms Associated with Eye, Hair, Skin Color, AB0 Blood Group, Sex, Y Chromosome Core Haplogroup, and Its Application to Study the Slavic Population].

This paper presents a method for genotyping a panel of 60 single nucleotide polymorphisms (SNPs) using single-stage PCR followed by hybridization on a hydrogel biochip. The pool of analyzed polymorphisms consists of 41 SNPs included in the HIrisPlex-S panel, 4 SNPs of the AB0 gene (261G>Del, 297A>G, 657C>T, 681G>A), markers of the AMELX and AMELY genes, and 14 SNP markers of the Y chromosome haplogroups: B (M60), C (M130), D (CTS3946), E (M5388), G (P257), H (M2920), I (U179), J (M304), L (M185), N (M231), O (M175), Q (M1105), R (P224) and T (M272). These genetic data allow one to predict the phenotype of the desired person according to the characteristics of eye, hair, skin color, AB0 blood group, sex, and genogeographic origin in the male line.

[The molecular-genetic analysis of mitochondrial DNA from the burnt bones: 'the limits of the possible' problem revisited].

The authors report the results of the demonstrative study continuing the cycle of interactive discussions pertinent to the possibility of obtaining reliable genetic information from the analysis of burnt bone fragments. Special emphasis is placed on the worthiness of these materials for genotyping of mitochondrial DNA (mtDNA) with the use of the standard analytical methods employed for the purpose of forensic medical expertise to investigate into the length polymorphism of the amplified mtDNA fragments (PAF) by means of sequencing with fluorescent detection. The study has demonstrated that the mtDNA fragments in the state suitable for genotyping can be found only in the preparations from the bone tissue exposed to the 'mild' thermal impact after which the affected bone is virtually indistinguishable from the native one as far as the outward appearance is concerned.

[On the problem of HIV infection in the objects of forensic medical expertise].

The authors overview the current state of research in the field of diagnostics and identification of the signs suggesting the presence of HIV in the materials obtained from the human corpses undergoing forensic medical expertise at different stages of their post-mortem changes. Another objective of the present work was to evaluate the risk of HIV infection for the medical personnel involved in the autopsy studies taking into consideration the significance attached in different countries to the problem of anti-infectious protection of the staff of the state institutions of forensic medical expertise. The authors discuss the possibilities and limitations of the application of the methods for HIV diagnostics, such as immunoenzymatic assays.

[The molecular genetic analysis of chromosomal DNA in burned bones].

The objective of the present study was a demonstrative consideration of the debatable problem concerning the possibility of obtaining reliable genetic information by the investigation of burned bones. The bone fragments with the identifiable external features of different degree of ignition (i.e.
