Haplotype is fundamental genetic information; it provides essential information for deciphering the functional and etiological roles of genetic variants. As haplotype information is closely related to the functional and etiological impact of genetic variants, it is widely anticipated that haplotype information will be extremely valuable in a wide spectra of applications, including academic research, clinical diagnosis of genetic disease and in the pharmaceutical industry. Haplotyping is essential for LD (linkage disequilibrium) mapping, functional studies on cis-interactions, big data imputation, association studies, population studies, and evolutionary studies. Unfortunately, current sequencing technologies and genotyping arrays do not routinely deliver this information for each individual, but yield only unphased genotypes. Here, we describe a high-throughput and cost-effective experimental protocol to obtain high-resolution chromosomal haplotypes of each individual diploid (including human) genome by the single-chromosome microdissection and sequencing approach.
单倍型是基本的遗传信息;它为解读遗传变异的功能和病因作用提供了重要信息。由于单倍型信息与遗传变异的功能和病因影响密切相关,人们普遍预期单倍型信息在广泛的应用中具有极高的价值,包括学术研究、遗传病的临床诊断以及制药行业。单倍型分型对于连锁不平衡(LD)作图、顺式相互作用的功能研究、大数据推算、关联研究、群体研究和进化研究至关重要。不幸的是,当前的测序技术和基因分型阵列并非常规地为每个个体提供此类信息,而仅产生未分型的基因型。在此,我们描述了一种高通量且经济高效的实验方案,通过单染色体显微切割和测序方法来获得每个个体二倍体(包括人类)基因组的高分辨率染色体单倍型。
