• Single Cell, Whole Genome Analysis of the Aging Human Cardiomyocytes

  In this study we have sequenced single cardiomyocytes from 12 individuals (ages from 0.4 to 82 yrs.). We have identified and characterized the somatic single-nucleotide variants (sSNVs). Our study indicates that cardiomyocyte sSNVs increased with age with distinctive mutational signatures.

• The molecular basis of inherited reproductive disorders

  The purpose of this study is to discover genetic mutations in patients who have GnRH deficient states. This includes individuals with variant forms of hypogonadotropic hypogonadism, including individuals who have somatic anomalies involving mid-line facial defects, renal agenesis, synkinesia, and ataxia, amongst others.

• Monosomy 7 delineates a primitive acute myeloid leukemia with adverse prognosis and responsiveness to epigenetic therapy

  The dataset comprises 27 single-cell multiome (ATAC + GEX) datasets generated from 13 patients with AML, collected across different stages of disease progression. In addition, matched long-read sequencing data from 5 samples were used to enable longitudinal analyses throughout the manuscript. Finally, bulk RNA-seq and ATAC-seq datasets from the cell line used in this study are also included.

• De novo mutations in cell-free foetal DNA (cffDNA)

  This project is to develop and validate a method to detect de novo mutations in a foetal genome through deep sequencing of cell-free DNA from the plasma of pregnant women. This data is part of a pre-publication release. For information on the proper use of pre-publication data shared by the Wellcome Trust Sanger Institute (including details of any publication moratoria), please see http://www.sanger.ac.uk/datasharing/

• Delineation of the heterogeneous molecular landscape of HRS cells and their biological contributions to forming comprehensive TME ecosystems.

  The tissue architecture of classic Hodgkin Lymphoma (CHL) is unique among cancers and characterized by rare malignant Hodgkin and Reed-Sternberg cells that are co-evolving in a complex ecosystem of immune cells in the tumor microenvironment. The lack of a comprehensive systems-level interrogation has hindered the description of disease heterogeneity and clinically relevant molecular subtypes. Here, we employed an integrative, multimodal approach to characterize CHL tumors using malignant cell sequencing, spatial transcriptomics and imaging mass cytometry. We identified four molecular subtypes (CST, CN913, STB, and CN2P) each characterized by distinct clinical features, mutational patterns, malignant cell gene expression profiles, and spatial architecture of immune cell populations. Functional modeling of CSF2RB mutations, a characteristic feature of CST, revealed dysregulated oncogenic signaling and changes in tumor microenvironment crosstalk. These findings highlight the significance of multi-dimensional profiling in elucidating patterns of molecular alterations that drive immune ecosystems and underlie therapeutically exploitable vulnerabilities.

• Drugging the catalytically inactive state of RET kinase in RET-rearranged tumors.

  Oncogenic fusion events have been identified in a broad range of tumors. Among them, RET rearrangements represent distinct and potentially druggable targets that are recurrently found in lung adenocarcinomas. We provide further evidence that current anti-RET drugs may not be potent enough to induce durable responses in such tumors. We report that potent inhibitors, such as AD80 or ponatinib, that stably bind in the DFG-out conformation of RET may overcome these limitations and selectively kill RET-rearranged tumors. Using chemical genomics in conjunction with phosphoproteomic analyses in RET-rearranged cells, we identify the CCDC6-RETI788N mutation and drug-induced mitogen-activated protein kinase pathway reactivation as possible mechanisms by which tumors may escape the activity of RET inhibitors. Our data provide mechanistic insight into the druggability of RET kinase fusions that may be of help for the development of effective therapies targeting such tumors.

• Transcriptional and functional profiling defines human small intestinal macrophage subsets

  Macrophages (Mf) are instrumental in maintaining immune homeostasis in the intestine, yet studies on origin and heterogeneity of human intestinal Mf are scarce. Here, we identified four distinct Mf subpopulations in human small intestine (SI). Assessment of their turnover in duodenal transplants revealed that all Mf subsets were completely replaced over time; Mf1 and Mf2, phenotypically similar to peripheral blood monocytes (PBMo), were largely replaced within 3 weeks, whereas two subsets with features of mature Mf, Mf3 and Mf4, exhibited significantly slower replacement. Mf3 and Mf4 localized differently in SI; Mf3 formed a dense network in mucosal lamina propria, whereas Mf4 was enriched in submucosa. Transcriptomic analysis showed that all Mf subpopulations subsets were markedly distinct from PBMo and dendritic cells (DC). Compared to PBMo, Mf subpopulations showed reduced responsiveness to proinflammatory stimuli, but were proficient at endocytosis of particulate and soluble material. These data provide a comprehensive analysis of human SI Mf population and suggest a precursor-progeny relationship with PBMo.

• GWAS in an Amerindian Ancestry Population Reveals Novel Systemic Lupus Erythematosus Risk Loci and the Role of European Admixture

  The study comprises SLE patients recruited from specialist rheumatology clinics from the United States, Mexico, Argentina, Chile and Peru. Two strategies were used to enrich samples for Native American ancestry: a. previously genotyped Hispanic and Latin American and US Native American individuals were selected according to their ancestry based on 253 ancestry informative markers as part of the Lupus Large Association 2 Study. The approximate 35% of the samples were primarily of European and Native American admixture was selected; b. the recruitment of patients took place primarily in countries with little African admixture. All samples were genotyped on the HumanOmni1-Quad BeadChip using manifest H at the Oklahoma Medical Research Foundation. The Illumina clustering algorithm with GenomeStudio v2011.1 was used.

• Genomics and Modification of Pain: A peripheral component identified using iPSCs with the S241T mutation

  We have capitalized on inherited erythromelalgia (IEM) as a well-characterized genetic model of chronic pain, and studied IEM patients carrying Nav1.7 mutations which affect channel activation and often produce hyperexcitability of DRG neurons. Whole exome sequencing was used to discover multiple gene variants that might contribute to neuronal excitability and that might serve as modifiers of sensory neuron firing, and identified the Kv7.2 channel as a contributor to differences in pain profiles between individuals.

• GWAS in Fibrosing Interstitial Lung Disease

  This study was a case-control genome-wide association study of 1616 non-Hispanic white cases and 4683 controls. Under an additive model for the minor allele at each SNP, we identified 19 SNPs, representing 7 chromosomal locations (5p15, 6p24, 7q22, 11p15, 15q14-15, 17q21, and 19p13), with genome-wide significant (P < 5x10-8) associations using the discovery samples included in this submission. We genotyped the 19 genome-wide significant SNPs in addition to 178 SNPs with 5x10-8 < P-value <.0001 and found 4 additional loci (3q26, 4q22, 10q24, and13q34) with genome-wide significant SNPs in the meta-analysis.
