• NHLBI TOPMed: Study of African Americans, Asthma, Genes and Environment (SAGE)

  This is a parallel case-control pharmacogenetic study of bronchodilator drug response among African American children with and without asthma. Each participant had spirometry measured using the KoKo PFT System. Asthmatic participants were administered with 4 puffs of HFA Albuterol. Healthy participants were given a baseline spirometry test. The overall goal is to identify genetic factors which are predictive of drug response in children with asthma. The principal tools include a questionnaire and biological specimen collection. Participants were 8-21 years old at time of recruitment. Children with asthma have physician-diagnosed asthma, symptoms and medications.

• Biology and Molecular Analysis of Human Hematopoiesis Genetics

  In this study we have performed exome sequencing using the hybrid capture method that has previously been described (Gnirke et al., Nature Biotechnology, 2009) on genomic DNA samples from patients with the congenital bone marrow failure syndrome that affects the erythroid lineage, specifically, Diamond-Blackfan anemia. This disease is characterized by a hypoplastic anemia and approximately 50% of cases are attributable to mutations in ribosomal protein gene subunits. The other 50% of cases do not have a known genetic etiology and the purpose of this study is to attempt to delineate such causes.

• Maternal Plasma Folate and DNA Methylation in Epigenome-Wide Meta-Analysis of Newborns

  Folic acid is routinely recommended for women trying to conceive to ensure proper fetal development. Mechanisms whereby periconceptional folate influences normal development and disease are poorly understood: epigenetics may be involved. This data represents meta-analysis results from a large epigenomics study to examine the association between maternal plasma folate during pregnancy and epigenome-wide DNA methylation using Illumina's HumanMethyl450 (450K) Beadchip in 1,996 newborns from two European cohorts. Results for all CpGs analyzed (419,905) are provided. These data may be downloaded through the dbGaP Authorized Access portal under phg000701.v1.

• Profiles of extracellular miRNA in cerebrospinal fluid and serum from patients with Alzheimer's or Parkinson's disease correlate with disease status and features of pathology

  We profiled the miRNA contents from cerebrospinal fluid and serum (using next generation sequencing) from postmortem patients diagnosed with Alzheimer's or Parkinson's disease, and neurologically normal controls. All biofluids were cell-free and patient matched, there was one cerebrospinal fluid and one serum sample from each of 70 patients with Alzheimer's disease, 67 patients with Parkinson's disease and 78 age-similar controls. We correlated the miRNA changes with measurements of neuropathology such as plaques, tangles and Lewy bodies.

• TCR Repertoire Sequencing to Evaluate the Diversity of Follicular Helper T Cells in HIV Infected Lymph Nodes

  The TCR repertoire of CD4+ T cells in human lymph nodes is a case-based analysis of the TCR repertoire of CD4+ T cells in human lymph nodes. The study aims to determine how HIV infection alters the repertoire complexity of follicular helper T cells (TFH) in relationship to other T cell subsets in the lymphoid compartment. This study performs TCR repertoire sequencing using Molecular Identifier Clustering-based Immune Repertoire Sequencing (MIDCIRS). We found TFH cells become clonally expanded and convergently selected in LNs from patients with chronic HIV infection.

• Cognitively Affected DMD Patients have Unique Methylation Signatures Compared to Cognitively Normal DMD Patients

  The overarching goal of this project was to identify changes in methylation patterns in Duchenne muscular dystrophy (DMD) patients with discordant symptoms using whole genome bisulfite sequencing (WGBS) from genomic DNA isolated from whole serum. DMD siblings (biological brothers) had the same genetic mutation in the dystrophin gene but with discordance in symptoms such as ambulation, cardiopulmonary function, and cognition. Trios (DMD sibling brothers and biological mother or father) and quartets (DMD sibling brothers and biological mother and father) were recruited for this study for intra- and inter-familial comparisons of the methylation of gene bodies.

• Genetics of Eating Disorders

  This genetic study examines Anorexia Nervosa, Bulimia Nervosa, and Binge Eating Disorder. We performed whole exome sequencing (WES) on 93 unrelated individuals with eating disorders (38 restricted-eating, 55 binge-eating) to identify novel damaging variants. Using an unbiased, data-driven approach, we prioritized candidate genes with an excessive burden of predicted damaging variants. We then empirically tested one top candidate pathway in a mouse model of binge-like eating. We identified an excess of novel damaging variants in 186 genes in the restricted-eating group and 245 genes in the binge-eating group. The list of genes significantly enriched (OR = 4.6, p

• human CMV-specific CD8+ T cells

  In this study we established a comprehensive workflow to collect multi-omics single-cell data using a commercially available micro-well based platform. This included whole transcriptome, cell surface markers (targeted sequencing-based cell surface proteomics), T cell specificities, adaptive immune receptor repertoire (AIRR) profiles and sample multiplexing. With this technique we identified novel paired T cell receptor sequences for three prominent human CMV epitopes. In addition, we review the ability of dCODE dextramers to detect antigenspecific T cells at low frequencies by estimating sensitivities and specificities when used as reagents for single-cell multi-omics.

• Mechanism of Decitabine response in MDS/AML patients

  Myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) with complex or monosomy karyotype show high prevalence of TP53 mutations (TP53m), poor response to induction chemotherapy and adverse outcome. These diseases may respond to decitabine but the mechanisms are presently unclear. This study investigates MDS/AML patients who were treated with decitabine for 10 days in a Phase II clinical trial. Serial samples were collected from patients before and at completion of decitabine treatment, morphologic remission and relapse. The samples were interrogated using single-cell transcriptomics to investigate potential interactions between leukemic and immune populations."

• Single cell transcriptomics of human kidney organoid endothelium reveals vessel growth processes and arterial maturation upon transplantation

  Human induced pluripotent stem cell-derived kidney organoids have potential for disease modeling and regenerative medicine purposes. However, they lack a functional vasculature in in vitro culture. Here, we transplanted kidney organoids at day 7+12 of differentiation in the coelomic cavity of chicken embryos. We then compared human endothelial cells from transplanted organoids to their respective untransplanted controls at d7+13 and d7+20 using scRNAseq. We demonstrate metabolic and phenotypic effect of transplantation with increased endothelial cell proliferation and differentiation to a fetal-like renal arterial/afferent arteriolar phenotype.
