Resolving the molecular basis of a Mendelian condition remains challenging owing to the diverse mechanisms by which genetic variants cause disease. To address this, we developed a synchronized long-read genome, methylome, epigenome and transcriptome sequencing approach, which enables accurate single-nucleotide, insertion–deletion and structural variant calling and diploid de novo genome assembly. This permits the simultaneous elucidation of haplotype-resolved CpG methylation, chromatin accessibility and full-length transcript information in a single long-read sequencing run. Application of this approach to an Undiagnosed Diseases Network participant with a chromosome X;13-balanced translocation of uncertain significance revealed that this translocation disrupted the functioning of four separate genes (NBEA, PDK3, MAB21L1 and RB1) previously associated with single-gene Mendelian conditions. Notably, the function of each gene was disrupted via a distinct mechanism that required integration of the four ‘omes’ to resolve. These included fusion transcript formation, enhancer adoption, transcriptional readthrough silencing and inappropriate X-chromosome inactivation of autosomal genes. Overall, this highlights the utility of synchronized long-read multi-omic profiling for mechanistically resolving complex phenotypes. Simultaneous profiling of the genome, methylome, epigenome and transcriptome using single-molecule chromatin fiber sequencing and multiplexed arrays isoform sequencing identifies the genetic and molecular basis of an undiagnosed Mendelian disease case with an X;13-balanced translocation.

In the past decade, our understanding of how new genes originate in diverse organisms has advanced substantially, and more than a dozen molecular mechanisms for generating initial gene structures were identified, in addition to gene duplication. These new genes have been found to integrate into and modify pre-existing gene networks primarily through mutation and selection, revealing new patterns and rules with stable origination rates across various organisms. This progress has challenged the prevailing belief that new proteins evolve from pre-existing genes, as new genes may arise de novo from noncoding DNA sequences in many organisms, with high rates observed in flowering plants. New genes have important roles in phenotypic and functional evolution across diverse biological processes and structures, with detectable fitness effects of sexual conflict genes that can shape species divergence. Such knowledge of new genes can be of translational value in agriculture and medicine. This Review discusses the various molecular mechanisms underlying the generation of new genes and highlights their important functions and phenotypes with an emphasis on the evolutionary forces underlying natural selection and sexual conflict.

Human adipose depots are functionally distinct. Yet, recent single-nucleus RNA sequencing (snRNA-seq) analyses largely uncovered overlapping or similar cell-type landscapes. We hypothesized that adipocyte subtypes, differentiation trajectories and/or intercellular communication patterns could illuminate this depot similarity–difference gap. For this, we performed snRNA-seq of human subcutaneous or visceral adipose tissues (five or ten samples, respectively). Of 27,665 adipocyte nuclei in both depots, most were ‘classical’, namely enriched in lipid metabolism pathways. However, we also observed ‘nonclassical’ adipocyte subtypes, enriched in immune-related, extracellular matrix deposition (fibrosis), vascularization or angiogenesis or ribosomal and mitochondrial processes. Pseudo-temporal analysis showed a developmental trajectory from adipose progenitor cells to classical adipocytes via nonclassical adipocytes, suggesting that the classical state stems from loss, rather than gain, of specialized functions. Last, intercellular communication routes were consistent with the different inflammatory tone of the two depots. Jointly, these findings provide a high-resolution view into the contribution of cellular composition, differentiation and intercellular communication patterns to human fat depot differences. Single-nucleus RNA sequencing of human visceral and subcutaneous adipose tissues is used to identify adipocyte subpopulations and explore their developmental trajectories and interactions.

Obesity strongly increases the risk of cardiometabolic diseases, yet the underlying mediators of this relationship are not fully understood. Given that obesity strongly influences circulating protein levels, we investigated proteins mediating the effects of obesity on coronary artery disease, stroke and type 2 diabetes. By integrating two-step proteome-wide Mendelian randomization, colocalization, epigenomics and single-cell RNA sequencing, we identified five mediators and prioritized collagen type VI α3 (COL6A3). COL6A3 levels were strongly increased by body mass index and increased coronary artery disease risk. Notably, the carboxyl terminus product of COL6A3, endotrophin, drove this effect. COL6A3 was highly expressed in disease-relevant cell types and tissues. Finally, we found that body fat reduction could reduce plasma levels of COL6A3-derived endotrophin, indicating a tractable way to modify endotrophin levels. In summary, we provide actionable insights into how circulating proteins mediate the effects of obesity on cardiometabolic diseases and prioritize endotrophin as a potential therapeutic target. Two-step Mendelian randomization, combined with multiple layers of omics evidence, implicates COL6A3-derived endotrophin as a mediator of coronary artery disease risk in the context of obesity.

Overcoming challenges associated with broad sharing of human genomic data 克服与广泛共享人类基因组数据相关的挑战

Since the Human Genome Project, the consensus position in genomics has been that data should be shared widely to achieve the greatest societal benefit. This position relies on imprecise definitions of the concept of ‘broad data sharing’. Accordingly, the implementation of data sharing varies among landmark genomic studies. In this Perspective, we identify definitions of broad that have been used interchangeably, despite their distinct implications. We further offer a framework with clarified concepts for genomic data sharing and probe six examples in genomics that produced public data. Finally, we articulate three challenges. First, we explore the need to reinterpret the limits of general research use data. Second, we consider the governance of public data deposition from extant samples. Third, we ask whether, in light of changing concepts of broad, participants should be encouraged to share their status as participants publicly or not. Each of these challenges is followed with recommendations. This Perspective discusses the definitions of ‘broad’ that have been used in the context of sharing of human genomic data and proposes a clarified and reformed terminology for describing genomic data sharing more precisely.
自人类基因组计划以来,基因组学的共识是数据应该广泛共享,以实现最大的社会效益。这种立场依赖于对“广泛数据共享”概念的不精确定义。因此,在具有里程碑意义的基因组研究中,数据共享的实施情况各不相同。在这个透视图中,我们确定了可以互换使用的广义定义,尽管它们具有不同的含义。我们进一步为基因组数据共享提供了一个明确概念的框架,并探讨了基因组学中产生公共数据的六个例子。最后,我们阐述了三个挑战。首先,我们探讨了重新解释一般研究使用数据的局限性的必要性。其次,我们考虑了来自现有样本的公共数据沉积的治理。第三,鉴于广义概念的变化,是否应该鼓励参与者公开分享他们作为参与者的身份。每个挑战之后都有建议。

Huntington’s disease, one of more than 50 inherited repeat expansion disorders1, is a dominantly inherited neurodegenerative disease caused by a CAG expansion in HTT2. Inherited CAG repeat length is the primary determinant of age of onset, with human genetic studies underscoring that the disease is driven by the CAG length-dependent propensity of the repeat to further expand in the brain3–9. Routes to slowing somatic CAG expansion, therefore, hold promise for disease-modifying therapies. Several DNA repair genes, notably in the mismatch repair pathway, modify somatic expansion in Huntington’s disease mouse models10. To identify novel modifiers of somatic expansion, we used CRISPR–Cas9 editing in Huntington’s disease knock-in mice to enable in vivo screening of expansion-modifier candidates at scale. This included testing of Huntington’s disease onset modifier genes emerging from human genome-wide association studies as well as interactions between modifier genes, providing insight into pathways underlying CAG expansion and potential therapeutic targets. A novel in vivo screening strategy identifies new modifiers of somatic CAG repeat expansion that contribute to age of onset in Huntington’s disease.
亨廷顿舞蹈病是50多种遗传性重复扩增疾病之一,是一种显性遗传性神经退行性疾病,由HTT2 CAG扩增引起。遗传性CAG重复序列长度是发病年龄的主要决定因素,人类遗传学研究强调,该疾病是由CAG重复序列在大脑中进一步扩展的CAG长度依赖倾向驱动的3,4,5,6,7,8,9。因此,减缓体细胞CAG扩张的途径有望用于改善疾病的治疗。几种DNA修复基因,特别是错配修复途径中的DNA修复基因,可以改变亨廷顿氏病小鼠模型的体细胞扩展。为了鉴定新的体细胞扩增修饰剂,我们在亨廷顿氏病敲入小鼠中使用CRISPR-Cas9编辑技术,在体内大规模筛选扩增修饰剂候选物。这包括对人类全基因组关联研究中出现的亨廷顿氏病发病修饰基因的测试,以及修饰基因之间的相互作用,从而深入了解CAG扩展的潜在途径和潜在的治疗靶点。
