Abstract The human genome has two alleles at each genetic locus, with one allele inherited from each parent. Allele- specificity has been widely observed and investigated across human transcriptome, epigenome and 3D chromatin organization respectively, as evidenced by the data collected from the GTEx project, the ENCODE project, and the 4DN project. However, the allele-level interplay among transcriptome, epigenome and 3D chromatin organization has not been systematically explored. In the proposal, we aim to leverage shared donors between these consortia and systematically investigate these connections at allele-level in many human tissue types. With the single cell datasets available from these donors, we will narrow down from tissue level to cell type level, and further interrogate these allele-specific cross-modality connections. In essential, our analysis seamlessly integrates two NIH Common Fund datasets, namely 4DN and GTEx datasets, and ENCODE datasets. With this integrated data source, biomedical researchers can easily navigate, browse, compare and investigate the high quality, high resolution, and comprehensive datasets regarding chromatin organization, regulatory elements, epigenomic status and transcriptional activity with allele-specificity and cell-type-specificity. Not only would this accomplishment have an enormous positive impact on the utility and usage of the Common Fund datasets, it would also help to promote open science and reproducible research in the areas of computational genomics and data science.

抽象的 人类基因组的每个基因位点都有两个等位基因，其中一个等位基因遗传自父母双方。等位基因- 特异性已在人类转录组、表观基因组和 3D 染色质中得到广泛观察和研究 从 GTEx 项目、ENCODE 项目和 4DN项目。然而，转录组、表观基因组和 3D 染色质组织之间等位基因水平的相互作用 还没有被系统地探索过。在提案中，我们的目标是利用这些机构之间的共同捐助者 联盟并系统地研究许多人体组织类型中等位基因水平的这些联系。和 从这些捐赠者提供的单细胞数据集，我们将从组织水平缩小到细胞类型水平， 并进一步询问这些等位基因特异性的跨模态连接。本质上，我们的分析是无缝的 集成了两个 NIH 共同基金数据集，即 4DN 和 GTEx 数据集以及 ENCODE 数据集。有了这个 集成的数据源，生物医学研究人员可以轻松导航、浏览、比较和研究高 关于染色质组织、调控元件、 表观基因组状态和转录活性具有等位基因特异性和细胞类型特异性。这不仅会 成就对共同基金数据集的效用和使用产生巨大的积极影响， 还将有助于促进计算基因组学领域的开放科学和可重复研究 数据科学。
