The quality of life of epilepsy patients without systemic treatment is generally lower. Single cell sequencing is to sequence genetic information at the resolution of a single cell, which is more accurate than traditional sequencing, and can classify cells without bias and construct cell maps. It can provide a new way for the study of epilepsy disease. In this paper, the development of single cell sequencing technology and its application in epilepsy are introduced, and its development prospect is prospected.展开更多
文摘为建立一种高同源区段的单核苷酸多态性(SNP)基因分型技术,通过构建本地Blast对SNP所在的200和400 bp区段进行同源性评估,并筛选出高同源区段的SNP。利用第一轮多重长PCR(polymerase chain reaction)捕获329个样本的9个高同源区段SNP所在的长片段,使用纯化后的第一轮PCR产物作为模板进行扩增子建库测序,检测样本共得2 928个SNP位点信息,测序成功率高达98.885 6%。利用Hardy-Weinberg(HWE)法则计算试验研究的9个高同源区段SNP位点的基因频率(p值均大于0.05,符合HWE法则),并与NCBI(national center for biotechnology information)中千人基因组数据库中获取的基因频率相比对,发现二者单碱基基因频率一致(误差限<0.15)。研究表明,利用多重长PCR靶向捕获技术结合二代测序技术为高同源区段的SNP分型提供一个准确、快速、大样本检测方案。
