测序技术和组装方法的进步使得能够定期生产高质量的基因组组装,以表征复杂区域。然而,在不同的尺度上,从较小的串联重复序列到大碱基重排,在许多人类基因组中有效地解释变异仍然存在挑战。我们提出了一个泛基因组研究工具包(PGR-TK),可以在多个尺度上分析复杂的泛基因组结构和单倍型变异。我们将PGR-TK中的图分解方法应用于II类主要组织相容性复合体,证明了人类泛基因组在分析复杂区域方面的重要性。此外,我们还研究了y染色体基因DAZ1/DAZ2/DAZ3/DAZ4,其中的结构变异与男性不育有关,x染色体基因OPN1LW和OPN1MW与眼部疾病有关。我们进一步展示了PGR-TK跨越395个复杂的重复医学重要基因。这突出了PGR-TK在解决基因组区域复杂变异方面的能力,这些区域以前过于复杂而无法分析。泛基因组研究工具包(PGR-TK)使用泛基因组图实现了灵活和可扩展的基因组变异表示、可视化和分析。
Advancements in sequencing technologies and assembly methods enable the regular production of high-quality genome assemblies characterizing complex regions. However, challenges remain in efficiently interpreting variation at various scales, from smaller tandem repeats to megabase rearrangements, across many human genomes. We present a PanGenome Research Tool Kit (PGR-TK) enabling analyses of complex pangenome structural and haplotype variation at multiple scales. We apply the graph decomposition methods in PGR-TK to the class II major histocompatibility complex demonstrating the importance of the human pangenome for analyzing complicated regions. Moreover, we investigate the Y-chromosome genes, DAZ1/DAZ2/DAZ3/DAZ4, of which structural variants have been linked to male infertility, and X-chromosome genes OPN1LW and OPN1MW linked to eye disorders. We further showcase PGR-TK across 395 complex repetitive medically important genes. This highlights the power of PGR-TK to resolve complex variation in regions of the genome that were previously too complex to analyze. The PanGenome Research Tool Kit (PGR-TK) achieves flexible and scalable representation, visualization and analysis of genomic variation using pangenome graphs.
