【摘要】:目的:對烏魯木齊市漢族育齡女性脆性X智力低下1(FMR1)基因突變情況進行檢測及統(tǒng)計分析,為脆性X綜合征(FXS)相關(guān)遺傳咨詢、孕前及產(chǎn)前診斷提供依據(jù)。方法:募集2015年6月至2016年9月就診的烏魯木齊市漢族育齡女性中符合研究目的的婦女作為目標人群,簽署《患者知情同意書》,抽取外周血,提取基因組DNA,應(yīng)用AmplideX?FMR1 PCR專利技術(shù)進行PCR擴增以及毛細管電泳,進行FMR1基因(CGG)n重復(fù)數(shù)檢測。采用國際分類標準將受檢女性分為陰性組及陽性組進行FMR1基因變異與卵巢功能不全的相關(guān)性研究,使用Χ2檢驗進行統(tǒng)計分析。結(jié)果:1.烏魯木齊市漢族育齡女性的FMR1基因檢測得到24種不同的等位基因,CGG重復(fù)數(shù)目的變異范圍為N=19~51次,其中最常見的CGG重復(fù)數(shù)N為29(43.46%),其次為30(27.69%)。2.檢出FMR1基因突變中間型(N=45-54)攜帶者1例,攜帶率為1/130。將中間型范圍擴大到N=40-54次時,檢測出中間型攜帶者7例,攜帶率為7/130。3.FMR1基因變異與卵巢功能不全相關(guān)性研究,Χ2=10.625,P0.05。結(jié)論:1.應(yīng)用AmplideX?FMR1 PCR技術(shù)進行FMR1基因(CGG)n重復(fù)數(shù)檢測省時省力,結(jié)果可靠,可以用作大樣本的篩查。2.新疆烏魯木齊市漢族育齡女性FMR1基因突變的發(fā)病情況與其他基于亞洲人群的研究結(jié)果基本相似,當(dāng)中間型被定義為CGG重復(fù)次數(shù)N=40-54(次)時,其攜帶率明顯高于亞洲地區(qū)的報道,與歐洲報道的結(jié)果相近。3.FMR1基因突變可能與卵巢功能不全相關(guān),FMR1基因CGG三核苷酸序列重復(fù)次數(shù)在26到34之間脆性X相關(guān)卵巢功能正常,超過26-34以外的CGG重復(fù)可能是發(fā)生卵巢功能不全的高危因素。
[Abstract]:Objective: to detect and analyze the mutation of fragile X mental retardation (1FMR1) gene in women of childbearing age of Han nationality in Urumqi, so as to provide evidence for genetic counseling and prenatal diagnosis of fragile X syndrome. Methods: from June 2015 to September 2016, women of childbearing age of Han nationality from June 2015 to September 2016 in Urumqi were recruited as the target population, and the patients' informed consent was signed and peripheral blood was drawn. Genomic DNA was extracted. PCR amplification and capillary electrophoresis were used to detect the CGGN repeats of FMR1 gene. The relationship between FMR1 gene mutation and ovarian dysfunction was studied by using the international classification standard. The FMR1 gene mutation and ovarian dysfunction were studied by using the X 2 test to analyze the relationship between FMR1 gene mutation and ovarian dysfunction. The result is 1: 1. FMR1 gene was detected in females of childbearing age in Urumqi city. The variation range of 24 different alleles was 1 951 times, in which the most common number of CGG repeats N was 2943.46 and the second was 3027.69g. One carrier with FMR1 gene mutation was detected, and the carrier rate was 1 / 130. When the range of intermediate type was expanded to 40 ~ 54 times, 7 cases of intermediate type carriers were detected. The rate of carrying was 7 / 130.3.The correlation between FMR1 gene mutation and ovarian dysfunction was studied, X = 210.625 (P0.05). Conclusion 1. Amplide XFMR1 PCR was used to detect the CGGN repeats of FMR1 gene. The results were reliable and could be used as a screening method for large samples. 2. The prevalence of FMR1 gene mutation in Han women of childbearing age in Urumqi, Xinjiang, was similar to that of other Asian population. When the intermediate type was defined as the number of CGG repeats, the carrier rate of FMR1 gene was significantly higher than that reported in Asia. The results were similar to those reported in Europe. 3. The mutation of FMR1 gene may be associated with ovarian dysfunction. The number of repeats of CGG trinucleotide sequence of FMR1 gene is between 26 and 34. More than 26-34 CGG repeats may be a risk factor for ovarian dysfunction.
