[Research of potentially linked variation of polymorphism of chromosome DNA in aspect of forensic expertise using molecular-genetic individualizing systems CD4, vWA and vWFII].
Investigated within the case study are parameters of disbalance of lineage (HC) for 4 micro-satellite locuses of human genome: LPL, CD4, vWA and vWFII. The above locuses are widely used, both in Russia and abroad, in molecular-genetic applications for personality identification. Meanwhile, according to cytogenetics criteria, CD4, vWA and vWFII, are located close to each other in the telomeric region 12pter-12p12 in the short chromosome 12 arm, therefore their potential genetic interdependence is still a topical issue. We found a reliable HC between locuses vWA and vWFII. Locus CD4 did not display HC with locuses vWA and vWFII or with locus LPL. The latter, which is located in chromosome 8 and which must have been negative control for HC, was shown to have no HC with any of the studied markers. Such results correlate well with data on the relative physical localization of CD4, vWA, vWFII and LPL. Multiplication of frequency of alleles (genotypes) is not acceptable in typing locuses vWA and vWFII within one multi-locus panel due to the genetic linkage of these markers demonstrated within the present case study, which is an important practical conclusion.
