• Whole Genome Sequencing Analysis in a Family of Discordant Twins With Non-Syndromic Microtia and Hemifacial Microsomia: Identification of Novel Candidate Genes and Variants

  This research is a non-NIH effort to discover the pathogenesis of non-syndromic microtia and to detect potential candidate genes. Microtia (OMIM 600674, 612290, 251800) is a spectrum of congenital anomalies and facial abnormalities, 90% of the cases followed by hearing loss. Two types of the disease are described in terms of connection to the affected syndromes: anomalies (syndromic) and only clinical manifestation (non-syndromic) associated with other symptoms. Though the exact pathogenesis of microtia remains unknown, pathogenic genes of majority of the microtia syndromic types have been identified. However, the genetic mutation of the non-syndromic microtia has not been confirmed. In this study, whole genome sequencing (WGS) was utilized to screen mutations in monozygotic discordant twins of congenital microtia-atresia and their family members. One of the twins, along with her grandfather, was discordant for microtia-atresia. By bioinformatic analysis of the WGS data from monozygotic twins with microtia and their non-microtia relatives, we proposed that among 28 identified potential genes, 4 of them (CNOT1, ODAD4, TBX15, and GIPC3) could be more responsible for non-syndromic microtia development and phenotypic features. Interested investigators may request to access the DNA genomic sequencing data of the study participants via dbGaP authorized access. In addition to raw genomic sequencing data, datasets of germline mutations and candidate gene mutations may also be available for investigators to request.

• Public Access Defibrillation Community Trial (PAD)(PAD-BioLINCC)

  Data Access NOTE: Please refer to the “Authorized Access” section below for information about how access to the data from this accession differs from many other dbGaP accessions. Objectives The Public Access Defibrillation (PAD) Community Trial sought to evaluate broad implementation of Public Access Defibrillators (PAD) in urban community units. Survival to hospital discharge of participants with out-of-hospital cardiac arrest was the main outcome measure. Survival was compared in community units (e.g., apartment or office buildings, gated communities, sports venues, senior centers, shopping malls) served by non-medical responders trained in CPR and use of automated external defibrillators (AEDs), to units receiving the traditional optimum community standard of care (i.e., rescuers trained to recognize a cardiac emergency, call 911, and initiate CPR). Background Sudden out-of-hospital cardiac arrest (OOH-CA) remains a significant cause of death, in spite of recent declines in overall mortality from cardiovascular disease. Existing methods of emergency resuscitation are inadequate due to time delays inherent in transporting trained responders with defibrillation capabilities to the side of the OOH-CA victim. Existing Emergency Medical Services (EMS) systems typically combine paramedic Emergency Medical Technician (EMT) services with some level of community involvement, such as bystander cardiopulmonary resuscitation (CPR) training. Some communities include automated external defibrillators (AEDs) at isolated sites or in mobile police or fire vehicles. Such an approach typically varies in effectiveness, with an incremental improvement in effectiveness seen in communities that organize and integrate services with the existing EMS system. However, optimal improvement in survival from sudden OOH-CA may require a program that utilizes volunteer non-medical responders (who may not have a traditional duty to respond to an emergency) trained to use AEDs. Participants The PAD trial was a prospective, randomized community based trial. More than 19,000 volunteer responders from 993 community units in 24 North American regions participated. The two study arms had similar unit and volunteer characteristics. Participants with treated out-of-hospital cardiac arrest in the two groups were similar in age (mean: 69.8 years), proportion of men (67 perecnt), rate of cardiac arrest in a public location (70 percent), and rate of witnessed cardiac arrest (72 percent). Conclusions Community units with volunteers trained in CPR and AEDs had significantly more participants surviving to hospital discharge than units with volunteers trained to use CPR only. There were 30 survivors among 128 definite cardiac arrests in the CPR+AED units and 15 survivors among 107 definite cardiac arrests in the CPR only units (p = 0.03). Serious adverse effects were rarely reported. No volunteers received inadvertent shocks, and no participants were shocked unnecessarily. AED maintenance problems were infrequent. A few participating volunteers reported severe stress related to responding to emergency situations. Although residential complexes represented 16% of the units and 29% of the treatable cardiac arrests, only 5% of the survivors were from residential complexes. Such information should be helpful for individual facilities that are considering implementing PAD programs. (NEJM 2004; 351:637-46).

• Introducing Federated EGA Affiliates: a newly defined tier in the Federated EGA Network

  We're happy to announce that we are now accepting Affiliates in the Federated EGA Network! Federated EGA is a global network of repositories enabling secure discovery and access to sensitive human data. Currently, Federated EGA consists of Central EGA (CEGA), which serves the global community, and nine national Nodes that serve respective jurisdictions. Did you know that the Federated EGA (FEGA) has always envisioned a third tier within the network? This brings us to FEGA Affiliates, recently defined in the newly approved "Federated EGA Structure and Organisation" document. This new tier broadens the range of institutions or organisations that can become part of FEGA. Thus begins a new era for the network. What is a FEGA Affiliate? A FEGA Affiliate archives and serves controlled-access data within its own governance scope, while still participating in federated discovery through the EGA catalogue. Affiliates can be individual organisations or institutions, healthcare genomics initiatives, consortia of institutions, as well as project-specific consortia (national or international). In practical terms, a FEGA Affiliate: Hosts and safeguards the data it archives. Submits non-personal metadata to CEGA so studies are discoverable and can receive EGA accessions. Manages permissions and data access workflows for its datasets. Provides data access and/or distribution, along with support, to authorised users. Key takeaways about FEGA Affiliates FEGA is now organised into three tiers: CEGA, FEGA Nodes, and FEGA Affiliates. Affiliates archive data from their own organisation and/or selected partner institutions (for example, an international consortium). Affiliates make studies discoverable through the EGA catalogue by submitting non-personal metadata for accessioning. Access decisions and conditions are managed locally by the Affiliate (e.g. distribution or access in a trusted research environment). Are you considering whether your institution or project might be a good fit as a FEGA Affiliate? Would you like to learn more about this tier? We have published a blog post that addresses potential common questions, providing answers on this topic. You can read it here.

• The Primary Open-Angle Glaucoma Genes and Environment (GLAUGEN) Study

  Background Information: Primary open-angle glaucoma (POAG) is an age-related, intraocular pressure (IOP)-dependent progressive optic neuropathy that ultimately leads to irreversible blindness. Vision loss from POAG is a condition of public health significance. Current evidence suggests that POAG is a polygenetic disease modified by environmental influences. Despite the fact that a positive family history of disease is an important risk factor for POAG, conventional linkage and candidate gene approaches have revealed less than 5% of the genetic component of the disease. Furthermore, there is no consensus on environment risk factors for POAG. Elevated IOP is the only modifiable risk factor for POAG; yet, lowering IOP slows, but does not halt the disease process. Study Objectives: The overall goal of our research is to elucidate the pathogenesis of POAG so that cost-effective disease detection and primary prevention strategies can be implemented. The primary aim of the Glaucoma Gene Environment Initiative (GLAUGEN), funded by the Human Genome Research Institute (NHGRI), is to discover genetic loci associated with POAG. The secondary aim of GLAUGEN, funded by NHGRI and the National Eye Institute, is to discover gene environment interactions in POAG. Methods and study populations: For this study, we have assembled cases and controls from three studies: the Nurses' Health Study (NHS), the Health Professionals Follow-up Study (HPFS) and the Genetic Etiologies of POAG (GEP) project based at Massachusetts Eye and Ear Infirmary (MEEI). This case-control group includes 1057 unrelated cases and 1272 controls. Members of the NHS and HPFS also have repeated environmental exposure data collected prior to a diagnosis of POAG. NHS - The Nurses Health Study started in 1976 under the direction of Dr. Frank E. Speizer. With funding from the NIH, registered nurses from 11 US states were invited to complete a detailed questionnaire regarding lifestyle and health biennially. Initially, 121,000 women responded to the baseline questionnaire. Currently, Dr. Susan Hankinson serves as the program director for the NHS. HPFS - The Health Professionals Follow-up Study began in 1986 under the direction of Drs. Walter Willett and Meir Stampfer. Under the auspices of the NIH, they enlisted 51,529 male health professionals from throughout the US to complete similarly designed biennial questionnaires. Beginning in 1990, questions regarding ocular health were added to biennial questionaires completed by health professionals participating in the NHS and HPFS. This allowed us to formulate (PI: S. Hankinson; NEI) and maintain (PI: L. Pasquale; NEI) a cohort at risk for POAG derived from the respective general cohorts who were under ophthalmic care. We then developed a definition of POAG that allowed us to identify cases from a population that was geographically dispersed. The centerpiece of this definition is the presence of reproducible visual field loss consistent with nerve fiber layer (NFL) dropout (the NFL contains the axons that comprise the optic nerve) on reliable tests. Reproducible visual field loss occurred in the context of anterior segment findings that did not suggest a secondary cause of elevated IOP and posterior segment findings that did not suggest a secondary cause of visual field loss. We selected controls from the cohort at risk for POAG on the basis of age, gender and time period when cases were identified. GEP - The Genetic Etiologies of POAG was initiated in 1996 with funding from the National Eye Institute under the direction of Dr. Janey Wiggs. The purpose of this work was to discover novel genetic loci associated with POAG. In the GEP, cases were derived predominantly from the Glaucoma Service at MEEI. The majority of cases had an examination by a glaucoma specialist and met the definition for POAG used in NHS and HPFS. Cases with only one reliable visual field consistent with NFL dropout were included if there was a cup-disc ratio of 0.7 or more. The majority of controls were patients who presented to the MEEI comprehensive ophthalmology service for routine eye examination or from spouses of MEEI patients with secondary forms of glaucoma. Other controls were identified from regional glaucoma screenings held throughout Massachusetts. Members of GEP have detailed ocular phenotype data but limited information on environmental exposures. This study is part of the Gene Environment Association Studies initiative (GENEVA, http://www.genevastudy.org) funded by the trans-NIH Genes, Environment, and Health Initiative (GEI). The overarching goal is to identify novel genetic factors that contribute to primary open-angle glaucoma through large-scale genome-wide association studies of three well-characterized cohorts of cases and controls, some in matched pairs. Genotyping was performed at the Broad Institute of MIT and Harvard, a GENEVA genotyping center. Data cleaning and harmonization were performed at the GEI-funded GENEVA Coordinating Center at the University of Washington.

• English Longitudinal Study of Ageing Genome-wide genotyping using the Illumina HumanOmni2.5-8

  These data are for a Genome Wide Association Study (GWAS) in the English Longitudinal Study of Ageing (ELSA, www.ifs.org.uk/elsa), building on the existing ELSA DNA Repository (EDNAR). This will establish a valuable resource for UK and international scientists, giving them access to GWAS genotyping data. Phenotype data, available on request, includes measures of personality, attitudes, behaviours as well as detailed social and economic outcomes; high quality biomarkers and other intermediate phenotypes; a range of more distal phenotypes, such as direct assessments of health (for example, hypertension, diabetes, muscle strength and cognitive function), and the opportunity to analyse existing biological samples for additional biomarkers, including metabolomic studies. Importantly, this resource would be matched with a near identical resource established in the United States for the Health and Retirement Study (HRS), giving the potential for high quality replication studies and comparative analyses.
