Description

New short Nucleotide tandem repetitive sequence site and application thereof

Technical field

The present invention relates to a kind of short Nucleotide tandem repetitive sequence site and application thereof.

Background technology

STR (Short Tandem Repeat. STR), claims again microsatellite DNA (microsatellite DNA), the Shi Yi class 2-6bp of repeating unit, multiplicity 10-60, the strand of dna connection tumor-necrosis factor glycoproteins of fragment length below 400bp; It produces reason is to slide in DNA replication dna process, or when copying and repair sliding chain and complementary strand base mispairing, cause disappearance or the insertion of one or several repeating unit.That STR has is widely distributed in genome, allelotrope is many, heterozygosity is high, somatotype result is stable, STR heredity meets Meng get Er law of inheritance (Koreth, J., et al. 1996. Microsatellites and PCR ge-nomic analysis.J. Pathol.178:239-248.) feature such as, and during a plurality of str locus seat joint-detection, individual recognition power and parentage exclusion probability are high.Thereby STR is with features such as its genetic polymorphisms, be used as s-generation genetic marker and be widely used in the fields such as medical science individual recognition, the drafting of human inheritance's collection of illustrative plates, paternity test, legal medical material evidence examination, effectively promoted forensic identification and changed to individual recognition from the individuality eliminating of material evidence sample in the past comprehensively.

At present, the technology of individual recognition mainly adopts STR-PCR to detect, to a plurality of str locus seat united typings, to determine parental right relation or individual recognition etc., all relatively ripe at experimental technique, but in the selection of str locus seat, does not seek unity of standard.In the detection kit that manufacturer provides both at home and abroad, site used is not quite similar.Early stage America and Europe selects 10 str locus seats to add 1 sex determining gene (E.A. Cotton, R.F. Allsop, J.F. Guest, R.R.E. Frazier, P. Koumi, I.P. Callow, A.Seager, R.L. Sparkes, Validation of the AmpFlSTR sGM Plus system for use in forensic casework, Forensic Sci. Int. 112 (2000) 151 – 161.).Along with technical development, database increase, comparison information difficulty strengthened afterwards, and the selection of str locus seat is also being updated.More influential database CODIS (Combined DNA Index System) Shi You U.S. FBI is based on 13 str locus seat (D3S1358 now, vWA, D16S539, D5S818, D7S820, CSF1PO, D13S317, TPOX, D8S1179, D21S11, D18S51, TH01, FGA.) build, thereby present most of STR detection kit manufacturer also increases or deletes that some sites are to improve detection efficiency and accuracy rate (D.J.French on the basis of these 13 core gene seats, R.L.Howard, N.Gale, T.Brown, D.G.McDowell, P.G.Debenhan, Interrogation of short tandem repeats using fluorescent probes and melting curve analysis:A step towards rapid DNA identity screening.Forensic Science. (2008) 333-339).The PowerPlex of Promega company for example 16 System test kits have comprised 13 core gene seats, and have increased PentaD, PentaE and tri-locus of AMELO; The AmpF/STR of American AB I company identifiler pCR Amplification Kit is that 13 core gene seats add D2S1338, D19S433 and AMELO; The other two test kit AmpFlSTR of its company sGM Plus PCR Amplification Kit and AmpFlSTR sinofiler pCR Amplification Kit has also done the increase and decrease of corresponding gene seat point.The unit of the similar detection kit of domestic production also has a lot, the DNA Typer that for example Ministry of Public Security two promotes ^tM15, middle dolantin joins the AGCU EX22 STR fluorescence detection reagent kit of Bioisystech Co., Ltd, and the locus that detects increases to 22.

The advantage of the str locus seat that above test kit is selected is, take 13 core gene seats that gain public acceptance as basis, the quantity of information obtaining is detected in more additional other sites to enrich, can more comprehensively reflect the otherness between individuality, and then complete the work such as individual recognition, patriarchy judgement.But be not all optimal selection in these locus used, for example FGA locus exists that sequence length is long, repeating unit is many but span is discontinuous, thereby affected the compatibility with other site, be unfavorable for using with the multiple system of a plurality of locus joint-detection; D19S433 locus is positioned at genome camber tumor-necrosis factor glycoproteins district, and amplimer design exists compared with burden, and the stability in this site is not high, and the available information quality providing while being applied to individual recognition and discrimination are not high; For another example D21S11 locus is positioned at the problem in genome camber tumor-necrosis factor glycoproteins region except existing, and also finds may have the CNV (situation of gene copy number variation in this locus region; When running into the improper pattern detection of gene copy number, can reduce the accuracy of this site STR somatotype, in individual's identification, adopt the effect of this locus also can have a greatly reduced quality.Along with the foundation of human genome collection of illustrative plates and the development of sequencing technologies, with lower cost, within the time faster, the full genome of the individual order of resurveying is become to possibility, and then can under larger quantity of information, filter out the str locus seat that discrimination is higher, promoted to be applied to selection and the renewal of the str locus seat in the researchs such as individual recognition.
