Genetics of Human Inherited Retinal Diseases (GHIRD)

The goal of this project is to identify novel mutations and genes involved in human retinal disorders, a stated priority of the National Eye Institute. To accomplish this, additional genes whose mutations cause inherited retinal diseases (IRD) will be identified by combining targeted gene panel sequencing, whole exome sequencing, and whole genome sequencing. We have collected about 1050 patient families around the world. In this proposal, we will identify the underlying mutations in these patients using a combination of targeted gene panel sequencing, whole exome sequencing, whole genome sequencing, bioinformatics, statistics, and functional studies. Genes targeted for gene panel sequencing are: ABCA4; ASIC2; JAG1; ABCC6; ARL3; ATP1B2; BBS1; BBS2; BBS4; OPN1SW; CAPN5; C21orf2; CA4; CACNA1F; CDH3; CHM; ERCC8; CLCN2; CLCN3; CLCN7; TPP1; CLN3; CLN5; CNGB1; CNGA1; CNGA3; COL2A1; COL9A1; COL11A1; CRX; VCAN; CTSD; TIMM8A; DMD; CLN8; ERCC6; EFEMP1; OPN1MW; GNAT1; GNAT2; GNGT1; GRM6; GUCA1A; GUCA1B; GUCY2F; GUCY2D; HARS; CFH; HK1; IDH3B; IMPDH1; IMPG1; KCNJ13; KIF11; LRP5; MAK; MITF; TRPM1; MTTP; MVK; MYO7A; NDP; NEK2; NEUROD1; NPHP1; NRL; OAT; OPA1; OTX2; PAX2; PAX6; PDCL; PCYT1A; PDE6A; PDE6C; PDE6G; PDE6H; PDE6B; PEX1; PEX6; PEX7; PEX10; PEX12; PEX13; PEX14; PFDN5; PGK1; PHYH; PIN1; PLA2G5; PPT1; PRKCZ; PEX19; PEX2; PEX5; RB1; RBP3; RBP4; OPN1LW; RDH5; PRPH2; RGR; RHO; GRK1; RLBP1; ROM1; RP9; RP1; RP2; RPGR; RPE65; RS1; SAG; ATXN7; CCL2; SLC6A6; ELOVL4; TEAD1; NR2F1; TIMP3; NR2E1; TTPA; TUB; TULP1; UCHL3; USH2A; CLRN1; VLDLR; BEST1; WFS1; ALMS1; MKKS; FZD4; OFD1; PEX3; CTSF; GBF1; ADAM9; RGS9; PEX11B; PROM1; UNC119; PRPF4; PRPF3; AIFM1; SLC24A1; LRAT; ASIC3; RAB28; PEX16; ITM2B; SLC4A7; IQCB1; CROCC; IFT140; DHX38; MFN2; NR2E3; USH1C; TOPORS; MERTK; FBLN5; CIB2; PRPF8; SDCCAG8; IFT27; TREX1; RRAS2; CEP164; ATF6; TRIM32; RIMS1; SNRNP200; CLUAP1; EMC1; ZNF423; TTLL5; AGTPBP1; RPGRIP1L; CRB1; TSPAN12; ARL2BP; AIPL1; PRPF6; FSCN2; ABHD12; PRPF31; TCTN3; IFT172; CNNM4; NPHP3; INVS; BBS9; FLVCR1; RDH8; IMPG2; WDPCP; RDH11; TMEM216; TMEM138; LZTFL1; CNGB3; AHI1; MKS1; CLN6; BBS7; POMGNT1; PEX26; SPATA7; KIZ; KLHL7; INPP5E; MDM1; CABP4; RPGRIP1; MCOLN1; CC2D2A; KIAA1549; SLC7A14; WDR19; NYX; CDH23; SEMA4A; MPP5; NMNAT1; TMEM237; PCDH15; C5orf42; GNPTAB; TMEM231; TCTN1; SRD5A3; BBS10; ZNF408; TTC21B; CSPP1; LPCAT1; DHDDS; PDZD7; PANK2; CEP290; OPA3; DNAJC5; PITPNM3; MFRP; HMCN1; ADGRV1; ARL6; FAM161A; TMEM126A; GNPTG; GJA10; RAX2; TUBGCP6; TMEM67; ACBD5; C12orf65; CDHR1; BBIP1; REEP6; CACNA2D4; RP1L1; CEP41; C1QTNF5; NXNL1; TTC8; USH1G; BBS5; ZNF513; RDH12; SLC38A8; C8orf37; VPS13B; NXNL2; BBS12; ADGRA3; LCA5; KCNV2; ADAMTS18; ARL13B; ATOH7; MFSD8; NPHP4; CCDC66; CYP4V2; CRB2; RD3; LRIT3; EYS; KIF7; CERKL; RGS9BP; C2orf71; GDF6; DTHD1; GPR179; CISD2; CCR2; PRCD; WHRN; ADGRA3.

Temptation Resistance Failures: Transdiagnostic Features and Influences

Multiple forms of psychopathology involve problems with resisting temptations and urges. This study utilizes experience sampling (ES) methodology to assess temptation resistance across different classes of temptations and urges including both common everyday temptations and more disorder-specific temptation classes. The study tests the hypothesis that the broad ability to successfully resist temptations and urges across temptation classes is a common features of the externalizing superspectrum (factor) of psychopathology, particularly the disinhibition spectra as defined by the Hierarchical Taxonomy of Psychopathology (HiTOP). Additional associations are expected to arise between reduced temptation resistance success for specific temptation classes and narrower symptom domains associated with the externalizing and internalizing spectra (e.g., binge eating, and nonsuicidal self-harm among internalizing symptoms). The study further tests genetic and environmental influences on temptation strength and resistance ability with a focus on polygenic scores, adverse childhood experiences and childhood neighborhood deprivation variables that have previously been related to externalizing. To address these issues, we will study up to 1200 subjects (minimum 1000) selected with enrichment for psychopathology. Subjects will be recruited from a combination of ResearchMatch, and targeted contact with Reddit groups, and targeted social media/online advertisements, with targeted recruitment of at least 150 subjects who indicate problems with SUD, alcohol use disorder (AUD) or nicotine dependence, 70 who indicate problems with gambling or other impulse control problems, 70 subjects with criminal/legal problems, and 70 subjects based on binge eating episodes 70 with self-injurious behavior, and 70 with obsessive-compulsive disorder. Subjects will complete the (Externalizing Spectrum Inventory-BF and HiTOP-SR) to measure externalizing and internalizing spectra. Diagnoses in key categories will be confirmed with structured diagnostic interviews. Subjects also complete information on childhood adversity and geocoding is used to assess environment during development. The two-week ES regimen collects data on the strongest types of temptations and urges experienced by the subject, their subjective strength, the goal of the urge (pleasure/relief from negative feelings), the level of conflict with other goals, whether the person attempted to resist the temptation, the resistance strategy, and resistance success, to allow assessment of the extent to which differences in each of these facets (and calculated temptation resistance efficacy) are related to narrow or broad dimensions of psychopathology. Whole genome sequencing with .5x coverage and imputation will be performed to allow generation of polygenic scores for externalizing and addiction in order to test the hypothesis that externalizing polygenic scores are related to poor temptation resistance efficacy across temptation classes.

Transcriptomic profiles of early and late passage metastatic colorectal cancer (mCRC) tumoroids

The breadth and depth at which cancer models are interrogated contribute to successful translation of drug discovery efforts to the clinic. In colorectal cancer (CRC), model availability is limited by a dearth of large-scale collections of patient-derived xenografts (PDXs) and paired tumoroids from metastatic disease, the setting where experimental therapies are typically tested. XENTURION is a unique open-science resource that combines a platform of 129 PDX models and a sister platform of 129 matched PDX-derived tumoroids (PDXTs) from patients with metastatic CRC, with accompanying multidimensional molecular and therapeutic characterization. This specific dataset is focused on a comparison of early and late passage tumoroids transcriptomes.

Study EGAS50000000108

RNA-Sequencing of cervical cancers

Question: Can we identify cervical cancer patients who are at risk for distant metastatic (DM) recurrence following treatment with radiotherapy, concurrent weekly cisplatin and brachytherapy (RTCT). Findings: An immune-based 55 gene risk score was developed using a cohort of 81 patients treated with RTCT that was strongly predictive of DM and cause-specific survival (CSS). The risk score was validated in two independent patient cohorts. A high immune metastatic risk score was associated with a high tumor mutational burden and a ‘cold’, immune-excluded tumor microenvironment at diagnosis. Meaning: The immune gene expression risk score may help to identify patients at risk of DM and potential targets for mitigating this risk.

Metformin for Oral Cancer Prevention

The M4OC-PREVENT clinical trial addressed whether metformin has utility in the prevention of oral cancer. It is a phase IIa clinical trial of metformin ER 2,000 mg per day given for 12-14 weeks to individuals with oral premalignant lesions, either oral leukoplakia or erythroplakia (which are precursors to oral cancer). The goal was to determine if metformin decreases the size of oral leukoplakia (clinical response). Additionally, effects on biomarkers of cancer risk and metformin effect were ascertained. The clinical trial was performed at the University of California San Diego Moores Cancer Center, the University of Minnesota, and the British Columbia Cancer Agency, with monitoring and oversight provided by the University of Arizona.

Selenium Chemoprevention: Benefits and Harms

Selenium is a trace element that may have anti-carcinogenetic effect, but heterogenous treatment effects have been observed. This genome-wide association study investigates if genetic variation modifies the effect of selenium chemoprevention in the Selenium and Celecoxib Trial, a randomized, double-blind, placebo-controlled trial conducted at the University of Arizona Cancer Center. The objective of the clinical trial was to determine whether daily intake of 200 µg/d of selenium as a supplement could reduce the risk for developing metachronous colorectal adenomas. The study participants were recruited between 2001 and 2011. Genome-wide association study was performed for 1,323 study participants who provided blood sample at the time of study entry.

Tissue Sampling and Biorepository to improve Cancer Cell Therapy

This study focuses on the elucidation of determinants of response and resistance to anti-CD19 CAR T-cells in large B-cell lymphoma. Plasma samples were collected prior to treatment and serially post CAR T-cell infusion. Pre-treatment and relapse tumor samples were also obtained as available. Germ-line DNA isolated from Peripheral Blood Mononuclear Cells (PBMCs) was collected for all patients when available. Circulating tumor DNA (ctDNA) and tumor DNA were sequenced using a target hybrid capture oligonucleotide pool. RNA-Seq was also performed on tumor isolated RNA. The authors identified several recurrent genomic alterations associated with relapse, and identified molecular thresholds that were predictive of response.

Immune Profiles Study

This study assesses glioma patient blood methylation longitudinally beginning pre-surgery through other clinically important timepoints. Progression and survival are studied in relation to methylation derived immunologic profiles and other characteristics. For this study, patients scheduled for surgery at University of California San Francisco (UCSF) for a possible newly diagnosed glioma (grades 2-4) or recurrent grade 2/3 glioma were consented and enrolled. Patients had blood collected pre-surgery and, if the pathology results confirm a glioma, every few weeks or months during their treatment (up to 30 total timepoints). Blood immunomethylomic profiles were measured at these timepoints to assess associations with glioma patient outcomes, clinical measures, other known prognostic markers, and imaging characteristics.

Centers for AIDS Research (CFAR) Network of Integrated Clinical Systems (CNICS)

Advances in antiretroviral therapies (ART) and patient management have improved survival of people living with HIV (PLWH). However, with exposure to ART and associated side effects and toxicities as well as to the virus itself, PLWH are at an increased risk of several chronic diseases. The Centers for AIDS Research (CFAR) Network of Integrated Clinical Systems (CNICS) research network integrates longitudinal clinical data and treatment management of PLWH and provides research infrastructure to support HIV-associated clinical, social, and behavioral outcomes and comparative effectiveness research using data collected from 8 Centers for AIDS Research clinical sites across United States. For detailed study description, see Kitahata et al. (2008, PMID:18263650).

Genomic Psychiatry Cohort (GPC) Whole Genome Sequencing and Genotyping Study

The Center for Genomic Psychiatry at the University of Southern California (USC), SUNY Downstate and an extensive network of academic medical centers have created the Genomic Psychiatry Cohort (GPC). The GPC consists of a large clinical cohort of patients with schizophrenia, bipolar disorder, and healthy controls. The data generation of genotyping and whole genome sequencing of the GPC has been done in collaboration with the USC and the Broad Institute of MIT and Harvard. Genome-wide association studies are being performed with the samples to identify genetic risks for psychiatric disease. Genotyping is also being used to determine ancestry informative markers and replication of candidate genes. Whole genome sequencing identifies functional variants associated with disease risk.

Preclinical Modeling of Leiomyosarcoma Identifies Susceptibility to Transcriptional CDK Inhibitors through Antagonism of E2F-Driven Oncogenic Gene Expression

Leiomyosarcoma (LMS) is a smooth muscle-derived mesenchymal cancer commonly found to have recurrent loss of tumor suppressor genes and a poorly defined oncogenic program. Empiric cytotoxic chemotherapy is the standard systemic treatment for LMS, and while more targeted and effective therapies are urgently needed, insights into therapeutic vulnerabilities in LMS have been limited by available preclinical models. We generated a panel of LMS patient-derived xenograft (PDX) models and evaluated fidelity to their tumors of origin using RNA sequencing and ultra-low passage whole-genome sequencing (ULP-WGS). Data available at dbGaP include RNA sequencing and ULP-WGS of primary tumors and early and late passages of PDX.

Genetics of Lymphatic Anomalies from Center of Applied Genomics (CAG) at CHOP

Lymphatic anomaly, a rare and devastating disease spectrum of mostly unknown etiologies, is characterized by diffuse or multicentric proliferation of dilated lymphatic vessels, and includes a variety of diagnoses: lymphangiectasia, central conducting lymphatic anomaly, generalized lymphatic anomaly, kaposiform lymphangiomatosis, and Gorham Stout disease. Currently, most treatments are considered palliative; lymphatic anomalies are often chronic debilitating conditions that require multiple yearly outpatient visits and hospital admissions for procedures that ameliorate symptoms, but do not correct the underlying cause. Identifying the causal genes will be hugely informative for our understanding of diseases. This will also allow for the development of affordable and successful diagnostic tests and therapies in keeping with "precision medicine" implementation.

Epigenetic Analysis of Malnutrition

The PROVIDE study (Dhaka, Bangladesh) is a randomized clinical trial platform which evaluated the efficacy of delayed-dose oral rotavirus vaccine as well as the benefit of an injectable polio vaccine replacing one dose of oral polio vaccine. This rigorous infrastructure supported the additional examination of hypotheses of vaccine underperformance. Primary and secondary efficacy and immunogenicity measures for rotavirus and polio vaccines were measured, as well as the impact of maternal and childhood malnutrition, environmental enteropathy, and additional exploratory variables. This study has been conducted to test the role of epigenetics in malnutrition, specifically the genome-wide role of histone modifications, which are known to provide a precise signature of metabolic state and immune system function.

Genomic Landscape of High-Grade Neuroendocrine Neoplasms

This project is a multi-omics study of high grade (grade 3) neuroendocrine neoplasms across diverse organs. Genomic analysis using low-pass whole genome sequencing for copy number analysis, whole exome sequencing and whole transcriptomic sequencing using RNAseq were performed. As high grade neuroendocrine neoplasms are highly lethal with a median survival of approximately 7 months, new insights are urgently needed for better prognosis, diagnosis and management. This study focuses on gene and pathway discoveries in this cancer, and includes samples from a diverse set of organs, including the lungs, gastroenteropancreatic tract, breast, prostate, head and neck and bladder. This study was made possible by a generous donation from The Helen B. Rodde Fund.

The Epigenomic Atlas of Early Human Craniofacial Development

Parallel profiling of six distinct histone modifications via ChIP-Seq in craniofacial tissue samples from individual human embryos was performed. Epigenomic marks imputed with ChromImpute and a 25-state chromatin state model of uniformly processed epigenomic data was produced through ChromHMM. Samples were obtained from the MRC-Wellcome Trust Human Developmental Biology Resource (HDBR) tissue bank. HDBR provided karyotypically and developmentally normal pharyngeal arch or craniofacial tissue from embryos between 4.5 and 10 post-conception weeks. This repository contains raw data (fastq) files from ChIP-seq and RNA-seq experiments associated with this project. Processed ChIP-seq data and imputed data for additional histone marks are available at GEO (Series GSE97752).

Enhancer signatures stratify and predict outcomes of non-functional pancreatic neuroendocrine tumors

Most pancreatic neuroendocrine tumors (PNETs) do not produce symptoms of hormonal excess and are hence considered “non-functional”. Their clinical behaviors vary widely, emphasizing the need for a robust classification with prognostic power. Using enhancer maps to infer regulatory programs, we find that the large majority of non-functional PNETs fall into two major sub-types that reflect alpha and beta endocrine cell ontogeny, respectively. Tumors of the different subtypes have similar clinical presentations and histology, but express distinct lineage-specifying transcription factors, ARX or PDX1. Here we provide the raw ChIP-seq and RNA-seq data of the PNET cohort in this study, as well as ChIP-seq data of ileal carcinoids.

Genomic landscape of Neutrophilic Leukemias of Ambiguous Diagnosis

Chronic neutrophilic leukemia (CNL), atypical chronic myeloid leukemia (aCML), and unclassified myelodysplastic syndrome/myeloproliferative neoplasms (MDS/MPN-U) are a group of rare, heterogeneous myeloid disorders. There is strong morphologic resemblance amongst these distinct diagnostic entities as well as lack of specific molecular markers and limited understanding of disease pathogenesis, which has made their diagnosis challenging. Treatment has remained empirical, resulting in dismal outcomes. We, therefore, performed whole exome and RNA-sequencing on a cohort of over 100 cases of these rare hematologic malignancies and present the most complete survey of the genomic landscape of these diseases to date.

Neutralizing Antibodies against West Nile Virus Identified Directly from Human B Cells by Single-Cell Analysis and Next Generation Sequencing

West Nile virus (WNV) infection is a mosquito-borne disease that can cause severe neurological illness. We analyzed the humoral response to WNV of subjects infected with WNV at different stages of the infection and at different levels of detail, from single cells to the repertoire level. We integrated single-cell analysis by microengraving with next-generation sequencing and identified four novel WNV neutralizing antibodies with potential use as therapeutics against WNV infection. The results indicate persistence of WNV-specific memory B cells and antibody-secreting cells in post-convalescent subjects and suggest that the antibody response itself does not predict the clinical severity of the disease.

Grady Trauma Project (GTP)

Not everyone exposed to traumatic experience develops Posttraumatic Stress Disorder (PTSD). Genetic background is one of the predisposing risk factors causing differential outcomes of trauma exposure. A primary goal of the Grady Trauma Project (GTP) is to pinpoint and understand genetic polymorphisms that contribute to development of PTSD. Both PTSD diagnosis binary labels and PTSD severity scores are studied as target phenotypes. Also, both candidate gene studies and genome-wide association studies are performed. Besides genetic variants, other measurements that are studied as risk factors for PTSD include lifetime history of trauma and peri-traumatic response. Study participants are primarily African American, trauma-exposed populations of low socioeconomic status recruited from Grady Memorial Hospital in Atlanta.
