临床上无异常个体的全基因组序列中的合子后单核苷酸嵌合体
作者：
合子后单核苷酸突变（pSNMs）已在癌症和其他一些过度生长的人类疾病在全基因组规模的研究，并发现发挥关键作用。然而，在临床上不显著的个体中，主要由于技术困难和缺乏匹配的对照组织样品，pSNM从未在全基因组规模上被鉴定，因此pSNM的全基因组特征仍然未知。我们开发了一种新的基于贝叶斯的镶嵌基因分型器和一系列有效的误差过滤器，使用这些技术，我们能够从3名临床上不显着的成人外周血DNA的1780 ×全基因组测序中识别出17个SNM位点。使用焦磷酸测序、单个克隆片段的桑格测序和多重连接依赖性探针扩增彻底验证pSNM。突变等位基因分数范围为5%-31%。我们发现C→ T和C→ A是主要的合子后突变类型，与肿瘤组织中的体细胞突变谱相似。模拟数据显示，总体突变率比癌症低一个数量级。我们在从同一个体获得的多个样品中检测到不同的pSNMs等位基因分数，包括血液，唾液，毛囊，口腔粘膜，尿液和精液样品，表明pSNMs可以影响多种来源的体细胞以及生殖细胞。其中两名成年人的孩子被诊断患有Dravet综合征。我们从这两个不相关的成年人中确定了Dravet综合征的致病基因SCN 1A中的两个非同义pSNMs，并发现突变等位基因被传递给他们的孩子，突出了检测pSNMs在遗传咨询中的临床重要性。
Postzygotic single-nucleotide mutations (pSNMs) have been studied in cancer and a few other overgrowth human disorders at whole-genome scale and found to play critical roles. However, in clinically unremarkable individuals, pSNMs have never been identified at whole-genome scale largely due to technical difficulties and lack of matched control tissue samples, and thus the genome-wide characteristics of pSNMs remain unknown. We developed a new Bayesian-based mosaic genotyper and a series of effective error filters, using which we were able to identify 17 SNM sites from∼ 80× whole-genome sequencing of peripheral blood DNAs from three clinically unremarkable adults. The pSNMs were thoroughly validated using pyrosequencing, Sanger sequencing of individual cloned fragments, and multiplex ligation-dependent probe amplification. The mutant allele fraction ranged from 5%-31%. We found that C→ T and C→ A were the predominant types of postzygotic mutations, similar to the somatic mutation profile in tumor tissues. Simulation data showed that the overall mutation rate was an order of magnitude lower than that in cancer. We detected varied allele fractions of the pSNMs among multiple samples obtained from the same individuals, including blood, saliva, hair follicle, buccal mucosa, urine, and semen samples, indicating that pSNMs could affect multiple sources of somatic cells as well as germ cells. Two of the adults have children who were diagnosed with Dravet syndrome. We identified two non-synonymous pSNMs in SCN1A, a causal gene for Dravet syndrome, from these two unrelated adults and found that the mutant alleles were transmitted to their children, highlighting the clinical importance of detecting pSNMs in genetic counseling.
