【摘要】:[目的]本課題基于Y染色體系統(tǒng)進化樹,選擇O、C、N支上的43個Y-SNP位點,采用MassARRAY技術(shù)對云南大理白族男性人群Y-SNP位點進行調(diào)查研究,獲得云南大理白族男性人群單倍群分布頻率以及遺傳結(jié)構(gòu)狀況,建立Y-SNP基礎(chǔ)DNA數(shù)據(jù)庫,為法醫(yī)學(xué)應(yīng)用奠定基礎(chǔ)。 [方法]在知情同意的原則下,嚴格按照準入標準(男性無關(guān)個體,三代以內(nèi)均為白族,無血緣關(guān)系),在云南大理州及其他地州采集278例云南白族男性個體的外周靜脈血5ml, EDTA-Na2抗凝,采用MassARRAY法檢測實驗樣本Y染色體上43個SNP位點的遺傳多態(tài)性,應(yīng)用SPSS19.0統(tǒng)計學(xué)軟件進行統(tǒng)計學(xué)分析。 本課題采用MassARRAY技術(shù),對樣本進行逐級篩選,分析了O支P101、L682、 M175、M324、M134、2611、M50(M110)、P164、Page23(M117)、M164、M162_1、 Page20(M119)、P201、F706、M312、P31、Pk4、F238、M95、L127.1、 F11、M88、M159、M188(M113)、M122、M101、P203.1的位點,分析了C支的V20、M347、M38、M105、M216、M356、M210的位點,以及分析了N支的L666、M231、L729、P189.2、L708、L732、M46(P105)位點,共計43個SNPs位點進行篩選分析。 [結(jié)果]獲得云南白族男性人群Y-SNP單倍型以及單倍型頻率,在278個無關(guān)白族男性個體中,共檢出28個Y-SNP單倍型,云南白族男性人群Y-SNP單倍群多樣性為0.0642。其中M175、M324、M134、P164、P201在白族人群中的單倍群分布頻率較高。白族未檢出單倍群P101、L682、M50、M164、M162_1、M312、P49、 V20、M347、M38、M105、P1892、L732、M356、M210。對于43個Y-SNPs位點來說,白族對應(yīng)的基因多樣性范圍從0.0000到0.6753。 [結(jié)論]依據(jù)人類Y染色體系統(tǒng)進化樹,分析云南白族278例男性樣本的43個Y-SNPs位點,獲得28個Y-SNP單倍群、單倍群分布頻率以及遺傳結(jié)構(gòu)信息,與文獻報道的白族以及其他少數(shù)民族的Y-SNP單倍群分布頻率進行分析,得出結(jié)論。不但可弄清中國云南大理白族的起源以及民族間的相互關(guān)系,研究各民族基因組結(jié)構(gòu)差別,分析其差別的遺傳學(xué)意義,為人類進化和中國各民族源流、遷徙和劃分提供生物學(xué)依據(jù),而且嘗試建立用MassARRAY分析檢測方法為云南人群Y-SNP研究提供相關(guān)數(shù)據(jù),同時為建立云南基礎(chǔ)DNA數(shù)據(jù)庫提供數(shù)據(jù)。
[Abstract]:[objective] based on the phylogenetic tree of Y chromosome, 43 Y-SNP loci were selected from the N branch of Oligon, and MassARRAY technique was used to investigate the Y-SNP loci in the male population of Dali Bai nationality in Yunnan Province. The distribution frequency of haploidy and genetic structure of male population of Bai nationality in Dali Yunnan Province were obtained. The basic DNA database of Y-SNP was established to lay the foundation for forensic application. [methods] under the principle of informed consent, the admission criteria were strictly followed. In Dali Prefecture and other prefectures of Yunnan Province, the peripheral venous blood 5ml and EDTA-Na2 anticoagulant were collected from 278 male individuals of Yunnan Bai nationality. The genetic polymorphisms of 43 SNP loci on Y chromosome were detected by MassARRAY method. SPSS19.0 statistical software was used for statistical analysis. 鏈棰橀噰鐢∕assARRAY鎶,
