【摘要】：目的·探索NOTCH1和JAG1的3’非編碼區(qū)(3’UTR)核苷酸變異與心臟圓錐動脈干畸形(CTD)的相關(guān)性。方法·采用病例-對照的研究方法,收集600名無22q11缺失的CTD患兒以及300名正常對照兒童。應(yīng)用高通量測序技術(shù)直接檢測樣本人群NOTCH1和JAG1 3’UTR區(qū)段的序列,篩選變異位點,通過PCR和Sanger測序法驗證變異的準確性。運用在線軟件Target Scan、Pic Tar和micro RNA.org對變異位點進行功能預(yù)測分析。結(jié)果·檢測出CTD患兒NOTCH1 3’UTR區(qū)存在1個新發(fā)突變和3個單核苷酸多態(tài)性(SNP),JAG1 3’UTR區(qū)存在3個新發(fā)突變和6個SNP位點。其中JAG1 3’UTR區(qū)有2個SNP位點(rs3840074、rs8708)的基因型在病例組和對照組間的分布差異有統(tǒng)計學(xué)意義(均P0.05)。預(yù)測結(jié)果顯示4個突變位點及2個有差異的SNP位點均可與微小RNA結(jié)合。結(jié)論·NOTCH1和JAG1 3’UTR區(qū)的核苷酸變異可能與心臟圓錐動脈干畸形的發(fā)生相關(guān)。
[Abstract]:Objective to investigate the correlation between 3 'noncoding region (3'UTR) nucleotide variation in NOTCH1 and JAG1 and (CTD) in cardiac conical trunk malformation. Methods A case-control study was conducted in 600 children with CTD without 22q11 deletion and 300 normal controls. The high throughput sequencing technique was used to detect the sequence of NOTCH1 and JAG1 3'UTR directly and to screen the mutation sites. The accuracy of the variation was verified by PCR and Sanger sequencing. The functional prediction of mutation sites was carried out by using online software Target sic Tar and micro RNA.org. Results one new mutation in the NOTCH1 3'UTR region and three single nucleotide polymorphisms in the JAG1 3'UTR region of (SNP) were detected in children with CTD. There were 3 new mutations and 6 SNP loci in the NOTCH1 3'UTR region. The genotypes of two SNP loci (rs3840074, rs8708) in the JAG1 3'UTR region were significantly different between the case group and the control group (P0.05). The predicted results showed that four mutation sites and two different SNP loci could bind to small RNA. Conclusion the nucleotide variation of NOTCH1 and JAG1 3'UTR may be related to the malformation of cardiac conical artery trunk.
