• HSC_population_dynamics___KX003_samples

  My research project aims to use the clonal dynamics of spontaneously occurring somatic mutations to answer fundamental questions about human haematopoietic stem cell (HSC) biology. The four major questions I will address are: 1. How do age and aging affect normal human HSC dynamics in vivo? 2. How do in vivo perturbations, particularly chemotherapy and increased levels of reactive oxygen species, affect HSC population dynamics? 3. Is response to in vitro perturbation heritable and/or correlated with other features such as age of individual and contribution of the lineage to peripheral blood? 4. How are HSC dynamics altered in people with early driver mutations (clonal haematopoiesis)?

• The_GENCODE_exome___sequencing_the_complete_human_exome

  We report the design of an extended set of targets for capturing the complete human exome, based on annotation from the GENCODE consortium. The extended set covers an addition 5,594 genes and 10.3 Mb compared to current sets which mainly target the CCDS database. The additional regions include potential disease genes previously inaccessible to exome resequencing studies, such as 43 genes linked to ion channel activity and 70 genes linked to protein kinase activity. In total, the new GENCODE exome set developed covers 47.9Mb and performed well in sequence capture experiments with HapMap and clinical samples. Samples within this study are prepared with either the CCDS or GENCODE exome products.

• Comparison of the performance of two commercial genome-wide association study genotyping platforms in Han Chinese Samples

  Affymetrix 6.0, Illumina OMNIExpress, and llumina Immunochip genotype data for Han Chinese population including rheumatoid arthritis cases and controls. Data is in PLINK binary format. Illumina genotype clustering was performed using Illumina’s BeadStudio software. SNPs were reclustered using the study samples, low quality subjects were removed, and a subset of clustering results were manually inspected and verified. All SNPs with GenCall scores less than 0.15 were excluded. For Affymetrix chips, clustering was performed using the program Birdseed version 2, as implemented using Affymetrix Genotyper Console v4.0, using the default quality control (QC) thresholds.

• Primary Cytotoxic T Cell Lymphomas Harbor Recurrent Targetable Alterations in the JAK-STAT Pathway

  Cytotoxic cutaneous T cell lymphomas (CTCLs) are uncommon but highly aggressive cancers of skin-homing cytotoxic T cells. These include the established World Health Organization (WHO) entity primary cutaneous gamma delta T cell lymphomas (PCGDTLs), the provisional WHO entity primary cutaneous CD8+ aggressive epidermotropic T cell lymphoma (PCAETCL), and samples that do not currently fit into a WHO category, referred to as cytotoxic CTCL-NOS (not otherwise specified). In this study, 35 CTCL cases were examined, and 9 PCAETCL cases were confirmed by CD8 expression and full-thickness epidermotropism. Whole genome sequencing (WGS) and bulk RNA sequencing were performed on these samples.

• PGRN/PAT: The genomic basis for susceptibility to drug-induced long QT syndrome (diLQTS)

  The goal of this study was to search for genetic variants that could be responsible for modifying the risk of drug-induced long QT syndrome (diLQTS). diLQTS is a relatively common adverse drug event and has been a leading cause for drug relabeling and withdrawal from the market. Our hypothesis, that variants in genes which regulate electrical properties in the heart modify the risk of diLQTS, was tested by sequencing approximately 225 patients of European descent using next-generation targeted captured or whole exome sequencing. Data from cases and controls (1:2) were analyzed to identify both rare and common genetic variation.

• ADHD Genomic Association Study

  Studies at Donders Institute for Brain, Cognition and Behaviour, Radboud University, Nijmegen, Netherlands, has recruited participants with ADHD and participants without ADHD, which included matched healthy controls and family members of participants with ADHD. ADHD participants met DSM-IV-TR criteria for ADHD. DNAs of these participants, 1005 samples, were anonymously genotyped with Illumina PsychArray. These samples were not part of the PGC-ADHD group. After removing family members, 820 case/control independent samples, including 211 ADHD cases, went through genomic association analyses. Results of ADHD risk genetic markers were compared with genetic markers associated with brain structure alterations in ADHD in adults and adolescents.

• Whole Exome Sequences of Human Embryonic Stem Cell Lines

  Human embryonic stem cells (hESCs) are a powerful tool for the study of human development and can form the basis of cellular disease models or therapies. However, the genetic make-up and stability of hESCs has not been systematically studied at a genome-wide level with single nucleotide resolution. We therefore sequenced the whole exomes of widely available hESCs. The data generated has provided new insights about the nature of acquired variation and the genomic integrity of the cell lines. We anticipate that this online resource will enable investigators to access raw sequencing data in order to interrogate cell lines for different disease and trait-associated genetic variants.

• Impact of Mobile Element Insertions on Human Transcriptome Variation

  Mobile DNA elements are ubiquitous in nearly all species and mobile element insertions can affect nearby gene expression through many mechanisms, from disrupting coding regions to initiating DNA methylation to altering RNA splicing patterns. Thousands of mobile element insertions are still polymorphic in human populations, and these polymorphic mobile element insertions (pMEIs) can contribute to transcriptome and phenotypic variation in humans. We identified and genotyped pMEIs using the whole genome sequencing (WGS) data from the Genotype-Tissue Expression (GTEx) project. We then used the extensive multi-tissue transcriptome data from the GTEx project to systematically assess the effects of pMEIs on human transcriptome variation.

• NHLBI TOPMed - NHGRI CCDG: Massachusetts General Hospital (MGH) Atrial Fibrillation Study

  The Massachusetts General Hospital (MGH) Atrial Fibrillation Study was initiated in 2001. The study has enrolled serial probands, unaffected and affected family members with atrial fibrillation. At enrollment participants undergo a structured interview to systematically capture their past medical history, AF treatments, and family history. An electrocardiogram is performed; the results of an echocardiogram are obtained; and blood samples are obtained. For the TOPMed WGS project only early-onset atrial fibrillation cases were sequenced. Early-onset atrial fibrillation was defined as an age of onset prior to 66 years of age. Comprehensive phenotypic and pedigree data for study participants are available through dbGaP phs001001.

• Genetic Analysis of Limb Malformation Disorders: Miller Syndrome Sequencing Study (LMD-MS)

  The overall goal of this project is to investigate the etiology and pathogenesis of malformations (i.e., birth defects) of the limb, concentrating on abnormalities of limb patterning such as limb deficiency/duplications and multiple congenital contractures. The exome sequences of two siblings and two unrelated individuals were obtained by massively parallel DNA sequencing. The four individuals were affected with Miller syndrome (OMIM: 263750). Additionally, the whole-genome sequences of a family of four were obtained with the method of Complete Genomics Incorporated (CGI). The two offspring were both affected with Miller syndrome and is the same sibling pair mentioned previously from whom exome sequences were also obtained.

• Linked Read Sequencing of Gastric Cancer Metastases for Complex SV Resolution

  In this study, linked read sequencing was performed on two ovarian metastases and matched normal tissue, from a patient with primary diffuse gastric cancer. Linked read sequencing is a DNA preparation technology whereby high molecular weight molecules of DNA are uniquely barcoded prior to fragmentation and sequencing, thus retaining information about genomic contiguity. This study performed an extended analysis of linked read sequencing data to resolve the complex structures of structural variants in the cancer genomes. Complex structural rearrangements were identified in the genomic region surrounding the known oncogene FGFR2, and the association between FGFR2 and gastric cancer metastasis was demonstrated in an organoid model.

• Somatic Copy Number Analysis of Endometrial Carcinomas

  Endometrial cancer (EC) is the most commonly diagnosed gynecologic malignancy in the United States and is the sixth leading cause of cancer death amongst American women. The purpose of this study was to identify somatic (tumor-specific) copy number alterations in 7 clear cell ECs, 31 serous ECs, 17 endometrioid ECs, and the clear cell components of 2 endometrioid/clear cell ECs. To this end, DNAs from de-identified primary endometrial tumors and matched non-tumor tissues or blood were hybridized to high-density Illumina Infinium HumanHap650Y Beadchips or to high-density Human660W-Quad Beadchips and the data analyzed to annotate somatic copy number alterations throughout the genome.

• A Multi-Omic Single-Cell Atlas of Human Gynecological Malignancies

  Matched single-cell transcriptomic sequencing (scRNA-seq) and single-cell chromatin accessibility sequencing (scATAC-seq) were performed for 11 fresh human tumors collected from the endometrium or ovary. More detailed information for each patient tumor will be provided in selected phenotype/attributes data. Both scRNA-seq and scATAC-seq assays revealed the underlying cellular heterogeneity in transcriptional output and in chromatin accessibility for each patient tumor specimen. In this work, we identified potential non-coding regulatory elements that mediate cell type-specific gene expression patterns. These data will serve as an important reference for the single-cell genomics and gynecologic oncology research communities.

• STAMPEED: Myocardial Infarction Genetics Consortium (MIGen)

  Myocardial infarction (MI) is a common complex disease and the leading cause of death and disability worldwide. The genetic basis of this disease is largely unknown. It has been thought that early-onset MI events would have a substantially greater heritability, thus making DNA collections with younger individuals desirable. More recently, genome-wide association studies have become feasible through the development of whole genome arrays and a large catalogue of common variants reported in the International HapMap database. This study aims to use Affymetrix genotyping platform to do a whole genome scan in 3000 early-onset MI cases and 3000 matched controls from 6 study collection sites.

• Exploring the Genomic Dark Matter of Neurodevelopmental Disorders

  Neurodevelopmental Disorders (NDDs) are a group of disorders that typically manifest early in development and may give rise to impaired cognition, communication, adaptive behavior, and psychomotor skills. This study aims to take a more comprehensive view into the genomic landscape of structural variants implicated in NDDs with intellectual disability (ID). We have evaluated the genome of families with a genetically unsolved severe NDD via optical genome mapping. This study identified likely pathogenic or pathogenic structural variants in known NDD genes, including BCL11A, OPHN1, PHF8, SON, and NFIA. Data is available in VCF format, following the standard filtering settings in Bionano Access and available as "variants_combine_filters_inMoleRefine1.vcf" files.

• RNA-sequencing from duodenal bipsies of Celiac disease patients

  Samples, in a form of PAXgene fixed and paraffin-embedded biopsies, were collected from the multi-site, double-blind, randomized, placebo-controlled trial, aimed at dose-finding and assessing the efficacy and tolerability of a 6-week treatment with ZED1227 capsules vs. placebo in subjects with well-controlled celiac disease undergoing gluten challenge. Total RNA was extracted from the PaxFPE biopsy specimens (n = 116) using additional cuttings from the samples on which histomorphometry was previously assessed. For the extraction, an RNeasy Kit (Qiagen, Hilden, Germany) was used according to the manufacturer’s instructions. Library preparation and next-generation sequencing (NGS) were performed by the Qiagen NGS Service. A total of 10 ng of purified RNA was converted into cDNA NGS libraries. Library preparation was quality controlled using capillary electrophoresis. Based on the quality of the inserts and the concentration measurements, the libraries were pooled in equimolar ratios and then sequenced on a NextSeq (Illumina Inc., San Diego, USA) sequencing instrument according to the manufacturer’s instructions, with 100 bp read length for read 1 and 27bp for read 2. The raw data were de-multiplexed, and FASTQ files for each sample were generated using bcl2fastq2 software (Illumina Inc., San Diego, USA).

• Association of Oxidative Stress Pathway Alterations with Risk of Treatment Failure in RTOG9512: A Randomized Trial of Hyperfractionation Versus Conventional Fractionation in T2 Squamous Cell Carcinoma of the Vocal Cord

  Based on the growing body of retrospectively collected and heterogeneously treated clinical cohorts and preclinical models, we investigated the clinical importance of NRF2 pathway alteration in an independent set of patients treated uniformly in the large prospective phase III trial RTOG 9512. We tested the hypothesis that patients with T2 glottic squamous cell carcinoma (SCC) harboring NRF2 pathway mutations would show radioresistance and have more local failure (LF) and locoregional failure (LRF) compared to those who did not have these mutations, using patients who received radiotherapy alone, thus removing potentially confounding effects of other therapies, like surgery or chemotherapy.
