• Tourette International Collaborative Genetics (TIC Genetics) Study - NJCTS and NIMH

  The Tourette International Collaborative Genetics (TIC Genetics) Study is an international collaboration of scientists and clinicians specialized in Tourette Disorder (TD) from more than 20 sites across the United States, Europe, and South Korea. The study was established to further our understanding of the genetic architecture of tic disorders by developing a large sample of genotypically and phenotypically well-characterized affected probands and their relatives. We employ state-of-the-art genetic technologies to identify major genetic variants contributing to TD and the most commonly comorbid disorders, such as Obsessive-Compulsive Disorder (OCD) and Attention-Deficit/Hyperactivity Disorder (ADHD). TIC Genetics is a direct result of work of the New Jersey Center for Tourette Syndrome (NJCTS) Sharing Repository (Heiman et. al., 2008; PMID: 19036136), funded by a grant from NJCTS Center of Excellence. Established in 2011 (Dietrich et. al., 2015; PMID: 24771252), the TIC Genetic study focuses on both on familial genetic variants with large effects within multiplex affected pedigrees and on de novo mutations ascertained through the analysis of apparently simplex parent-child trios with non-familial tics. In May 2017, we published a whole-exome sequencing study on apparently 311 parent-child trios (Willsey et. al., 2017; PMID: 28472652). These data, both phenotypes and sequencing data, are available through dbGaP. There were 120 subject samples included in the publication that did not have consent for sharing. These are excluded from dbGaP.In November 2021, we published a whole-exome sequencing study on 13 multiplex TD families (Cao et. al., 2021). These data, both phenotypes and sequencing data, are available through dbGaP.

• Everything you need to know about Federated EGA Affiliates: Q&A

  Addressing common questions about Federated EGA (FEGA) Affiliates and providing answers. FEGA Affiliates have recently been defined as the third tier within the newly approved “Federated EGA Structure and Organisation” document, alongside Central EGA (CEGA) and the FEGA Nodes. In this blog post, we aim to answer the questions that may arise on this topic. For more general information about FEGA Affiliates, you can refer to this blog post. Let's now start with the questions and answers! What is the difference between a FEGA Affiliate and a FEGA Node? FEGA Nodes A FEGA Node is a national-level service that accepts submissions and provides archiving and access services within a single country's jurisdiction. Nodes provide end-to-end services for submitters in that jurisdiction, including submission support, processing, permissions management, and distribution. FEGA Affiliates A FEGA Affiliate is not a national submission service. Instead, it archives data from its own legal entity and/or selected partner institutions (for example, consortium partners). Affiliates are designed for organisations and consortia that need to keep data stewardship and access decisions within their own governance model, while still enabling discovery through the broader FEGA ecosystem. What do Affiliates commit to? Here is a practical checklist of the core expectations for a FEGA Affiliate. FEGA Affiliate checklist Discovery and metadata Submit non-personal metadata to CEGA to obtain EGA accessions and enable discovery (with metadata validation handled by the CEGA Helpdesk). Operations and resilience Maintain a data storage system and a defined backup/recovery approach. Ensure operational capacity (personnel and infrastructure) to deliver Affiliate services. Maintain systems and practices that support local data security and align with EGA best-practices. Access and user support Provide data distribution or access (e.g in a trusted research environment) to authorised users to datasets hosted at the Affiliate. Provide permissions management for datasets archived by the Affiliate (the CEGA DAC (Data Access Committee) Portal is always at your disposal to use). Provide a minimal helpdesk with sufficient capacity to support relevant DACs and approved users. Membership term Commit to a minimum membership term of four years. Governance and participation (lightweight by design) Affiliates integrate into the FEGA network operationally, but without the committee obligations associated with Nodes. When is becoming an Affiliate the right fit? Consider the Affiliate tier if: You host (or plan to host) controlled-access datasets that must be managed under your organisation’s or consortium’s governance, you want studies to be discoverable through EGA, but need access control and/or distribution to remain local, and you are not aiming to operate a national submission service tier.. What if a FEGA Node already exists in my jurisdiction? We encourage any potential Affiliate to reach out to their national FEGA Node to explore collaboration at the national level. Why? Federated models within a country already exist in FEGA, where a national Node operates like a Central EGA for their country. FEGA Nodes can also represent the interests of any Affiliates within their jurisdiction at the FEGA Committees. FEGA Nodes have experience and can support you on your FEGA journey. Ready to join as a FEGA Affiliate? We’re excited to open this formally defined pathway for organisations and consortia to participate in the federation. If you think the FEGA Affiliate tier fits your needs, start by assessing: Your scope (organisation/consortium-held data rather than public external submissions), Your ability to provide the core services (permissions, distribution/access, helpdesk, monitoring), and Your readiness to submit non-personal metadata to CEGA for accessioning and discovery. To express interest, please contact us here, and we'll help you understand the onboarding steps and how Affiliates integrate into the FEGA network.

• Resistance to Latent Mycobacterium tuberculosis Infection in South Africa: Immunologic Profiling

  Despite significant exposure to Mycobacterium tuberculosis (Mtb), some humans remain uninfected, as defined by persistently negative immune sensitization tests (tuberculin skin test, TST; interferon gamma release assays, IGRA). To explore mechanisms of natural resistance to Mtb infection, we profiled tissues from highly-exposed Mtb contacts from South Africa. The cohort in this submission were gold miners in South Africa who had worked in the mining industry ≥ 15 years with presumed high Mtb exposure, based on extreme tuberculosis incidence rates and high prevalence of latent Mtb infection (Chihota et al. 2022, PMID: 35302992; Ntshiqa et al. 2021, doi: 10.12688/gatesopenres.13191.1). TST and IGRA testing were performed at enrollment of gold miners, some of whom remained available for repeat testing at 12 months.

• Urothelial Cancer - Genomic Analysis to Improve Patient Outcomes and Research (UC-GENOME): A Bladder Cancer Advocacy Network (BCAN)-Led Collaborative Research Pilot Study

  UC-GENOME is a real-world cohort of patients with metastatic urothelial carcinoma (UC). The study consisted of two co-equal aims: 1) to provide targeted DNA sequencing for clinical decision making at no cost to patients; and 2) to create a resource for collaborative translational science including a clinically annotated biobank. The submitted data represents the foundational analysis of 218 patients accrued at 7 academic medical centers. The analysis includes 176 patients with both targeted DNA sequencing and RNA sequencing. The genomic data was combined with clinical variables to model response to chemotherapy and immune checkpoint inhibitors (ICI). Due to additional sharing restrictions, data from one site can be found in phs003094.

• Germline Whole-Exome Sequencing of Lung Cancer in EAGLE

  EAGLE is a large population-based case-control study designed and conducted to investigate the genetic and environmental determinants of lung cancer and smoking persistence using an integrative approach that allows combined analysis of genetic, environmental, clinical, and behavioral data. Here, we applied whole exome sequencing (WES) to EAGLE study, in a group of 2,777 Italian subjects (including 1,461 lung cancer cases and 1,316 healthy controls). We derived gene-level burden tests to explore the cumulative effect of deleterious rare variants within protein-coding genes and the lung cancer risk. Additionally, at this site we include WES datasets of 1259 healthy controls from 1054 PLCO (The Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial) subjects and 205 ACS (The American Cancer Society study) subjects.

• Cergentis FFPE-TLC

  In this study, formalin-fixed paraffin-embedded targeted locus capture (FFPE-TLC) sequencing is used as a novel technology for targeted detection of tumor-specific genomic structural variants (SVs) in the primary tumor of 29 colorectal cancer patients with metastatic disease. The tumor region was macrodissected and sequenced for 29 patients, and the "normal" region of the same slide was macrodissected and sequenced for 8 of these patients. SVs were found in the common fragile site (CFS)-associated genes MACROD2, PRKN, FHIT and WWOX as well as SVs caused by three LINE transposable elements. Tumor-specificity of selected SVs was independently verified by droplet digital PCR of tumor tissue DNA and their applicability as plasma circulating tumor DNA biomarkers was demonstrated.

• The dataset of Southeast Borneo individuals (Banjar and Ngaju ethnic groups) was used as comparative data to determine the Asian parental population of the Malagasy. Our study found strong support for an origin of the Asian ancestry of Malagasy among the Banjar.

  Malagasy genetic diversity results from an exceptional proto-globalisation process that took place over a thousand years ago across the Indian Ocean. Previous efforts to locate the Asian origin of Malagasy have highlighted Borneo broadly as a potential source, but so far no firm source populations have been identified. Here, we have generated genome-wide data from two Southeast Borneo populations, the Banjar and the Ngaju, together with published data compiled from populations across the Indian Ocean region. We find strong support for an origin of the Asian ancestry of Malagasy among the Banjar. This group emerged from the long-standing presence of a Malay Empire trading post in Southeast Borneo, which favoured admixture between the Malay and an autochthonous Borneo group, the Ma’anyan. Reconciling genetic, historical and linguistic data, we show that the Banjar, in Malay-led voyages, were the most probable Asian source among the analysed groups in the founding of the Malagasy gene pool.

• The_Genomic_Advances_in_Sepsis__GAinS__RNA_seq

  Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. This cohort comprises a subset of patients enrolled in the Genomic Advances in Sepsis (GAinS) study, an established biobank of adult sepsis patients. Patients with sepsis due to community acquired pneumonia or faecal peritonitis were recruited from 34 hospitals across the UK from 2005-2018, with samples for functional genomics and detailed clinical information collected on the first, third and/or fifth day following ICU admission. RNA was extracted from leukocytes isolated at the bedside using LeukoLOCK kits. We have previously identified sepsis response signatures (SRSs), transcriptomic endotypes that are associated with differential early mortality (Davenport et al, Lancet Respir Med, 2016; Burnham et al, AJRCCM, 2017) and response to treatment in a clinical trial (Antcliffe et al, AJRCCM, 2018). We generated RNA sequencing data on 903 samples, including 134 samples repeated from our previously released microarray data. Libraries were prepared using NEB Ultra II Library Prep kits (Illumina) and sequenced on a NovaSeq 6000. Reads were aligned to the reference genome (GRCh38) using STAR and gene counts quantified using featureCounts (annotation Ensembl v99). Counts were TMM-normalised and log-transformed. Following QC, processed data were available on 864 samples from 667 unique patients.

• Clinical evaluation of long read sequencing-based episignature detection in developmental disorders

  Some developmental disorders (DD) are marked by specific genome-wide methylation changes, known as episignatures, which can support diagnosis and reveal underlying mechanisms. Current methods rely on indirect methylation profiling. Here, we assessed whether long-read whole genome sequencing with nanopore technology could directly detect both episignatures and genetic variants. We sequenced forty controls and twenty DD patients, using clustering and dimensional reduction to compare methylome patterns with microarray-based signatures. Our classifiers accurately identified episignatures in 17 of 19 patients with pathogenic variants, matching microarray results. This study shows nanopore sequencing enables comprehensive, haplotype-aware genomic and epigenomic analysis for DD diagnostics.

• Human Epilepsy Genetics: Mosaic Mutations in Focal Epilepsy

  This study investigates the role of somatic mosaic mutations in human focal epilepsies, including focal cortical dysplasia (FCD) and mesial temporal lobe epilepsy (mTLE). It leverages genomic and single-cell transcriptomic data from surgically resected brain tissue to identify pathogenic variants and characterize their effects on specific cell types and molecular pathways. The study employs methods such as deep whole-exome and targeted sequencing, single-nucleus RNA sequencing (snRNA-seq), and integrated genotype-transcriptome profiling (e.g., GO-TEN) to define the cellular architecture and functional consequences of mosaic mutations. Data generated under this project aim to elucidate mechanisms of epileptogenesis and support discovery of potential therapeutic targets.

• Molecular response of AML blasts to Aza-treatment.

  Azacytidine (Aza) treatment is effective in some patients with acute myeloid leukemia (AML). Clinical observations suggest that DNMT3A-mutant patients represent a subgroup of AML patients that responds particularly well to Aza-treatment. Data coming from a mouse model support this finding and we have already generated molecular data suggesting a molecular pathway involved in Aza-response in DNMT3A-mutant AML patients. We now aim to validate these findings in primary AML-blasts. To this end, we have FACS-sorted blasts from patients with AML prior to and under Aza-treatment and plan to correlate pre-treatment as well as on-treatment methylomes to clinical Aza-response.

• Methylation-based classification of human mesenchymal chondrosarcoma

  We applied methylome and copy number profiling to a set of 45 well characterized MCS cases to evaluate their potential diagnostic value. Notably, the findings were reproducible also when analysing the round cell and cartilaginous component separately. Furthermore, four outliers were identified by methylome profiling for which the diagnosis had to be revised. Methylome profiling represents a sensitive, specific and reliable tool to support the diagnosis of MCS, particularly if only the round cell component is obtained in a biopsy and the diagnosis is not suspected. It can furthermore aid in confirming the diagnosis in case RNA sequencing for the HEY1::NCOA2 fusion transcript is not available.
