The National Institute of Neurological Disorders and Stroke (NINDS) Human Genetics Resource Center: DNA and Cell Line Repository (the NINDS Repository): Cerebrovascular Disease/Stroke Study

ABSTRACT:

The National Institute of Neurological Disorders and Stroke (NINDS) Human Genetics Resource Center: DNA and Cell Line Repository (the NINDS Repository), banks phenotypic data and biological samples, including from individuals with cerebrovascular disease, in order to facilitate gene discovery in neurological disorders. Those samples are used in a number of studies, and genotyping data from studies using this resource are encouraged to be shared via dbGaP. Many studies have already shared data in this fashion, which in turn, can be linked back to the biologicals banked at the NINDS Repository.

Stroke is the third leading cause of death in the United States, and is an acute neurological event leading to death of neural tissues. Although the majority of strokes are ischemic strokes, meaning there is oxygen deprivation to the brain, almost 20% of strokes are hemorrhagic, resulting from bleeding into the brain. Samples available in cerebrovascular disease in the NINDS Repository, include but are not limited to those from individuals affected with the following: ischemic stroke, hemorrhagic stroke, intracranial aneurysm (both ruptured and unruptured), transient ischemic attack, arteriovenous malformations, and others. Many studies contribute to the NINDS Repository collection in an ongoing manner and others are being added regularly. These studies include samples from the Vitamin Intervention for Stroke Prevention (VISP) study, the Ischemic Stroke Genetics Study (ISGS), the Familial Intracranial Aneurysm study, and many others.

There is also an associated Control collection (see dbGaP and Coriell). Others studies may use cases from the NINDS repository, controls from the NINDS repository, as well as cases, and controls, from other sources. A subset of subjects from The National Institute of Neurological Disorders and Stroke (NINDS) Human Genetics Resource Center: DNA and Cell Line Repository (the NINDS Repository): Cerebrovascular Disease/Stroke Study was utilized in the Ischemic Stroke Genetics Study (ISGS) study.

<h4>Background and purpose</h4>The Phosphodiesterase 4D (PDE4D) gene was reported recently to be associated with ischemic stroke in an Icelandic population. The association was found predominately with large vessel and cardioembolic stroke. However, 2 recent reports were unable to confirm this association, although a trend toward association with cardioembolic stroke was reported. None of the reports included significant proportions of blacks. We tested for genotype and haplotype association of ...[more]

Project description:The third leading cause of death in the United States, stroke is an acute neurological event leading to death of neural tissues. Although the majority of strokes are ischemic strokes, meaning there is oxygen deprivation to the brain, almost 20% of strokes are hemorrhagic, resulting from bleeding into the brain. Stroke is a complex disorder and likely multigenic in nature, resulting from a combination of genetic and environmental factors. These well characterized risk factors that contribute to the incidence of stroke include hypertension, cardiac disease, sickle cell disease, hyperhomocysteinemia, family history of stroke and smoking. ISGS aim is to perform a prospective genetic association study of ischemic stroke focusing on the hemostatic system. ISGS is a 5-center case-control study of first-ever ischemic stroke cases and concurrent controls individually matched for age, sex and recruitment site. This data includes that from subjects both banked in the <a href="http://ccr.coriell.org/Sections/Collections/NINDS/?SsId=10"> NINDS repository</a> with biologicals publicly available, and those whose samples are not banked/not available.  This study utilized the <a href="./study.cgi?id=phs000005">NINDS Repository Cerebrovascular/Stroke Study</a>, and <a href="./study.cgi?id=phs000004">neurologically normal controls</a> from the sample population which are banked in the National Institute of Neurological Disorders and Stroke (NINDS Repository) collection for a first stage whole genome analysis.

Project description:The National Institute of Neurological Disorders and Stroke (NINDS) Human Genetics Resource Center: DNA and Cell Line Repository (<a href="http://ccr.coriell.org/Sections/Collections/NINDS/?SsId=10">the NINDS Repository</a>), banks phenotypic data and biological samples, including from individuals with motor neuron disease, in order to facilitate gene discovery in neurological disorders. Those samples are used in a number of studies, and genotyping data from studies using this resource are encouraged to be shared via dbGaP. Many studies have already shared data in this fashion, which in turn, can be linked back to the biologicals banked at the NINDS Repository. Motor Neuron Disease is characterized by selective degeneration of the motor neurons of the spinal cord, brainstem, or motor cortex. Clinical subtypes are distinguished by the major site of degeneration. In Amyotrophic Lateral Sclerosis (ALS), there is involvement of upper, lower, and brainstem motor neurons. In progressive muscular atrophy and related syndromes, the motor neurons in the spinal cord are primarily affected. With progressive bulbar palsy, the initial degeneration occurs in the brainstem. In primary lateral sclerosis, the cortical neurons are affected in isolation (Adams et al, Principles of Neurology, 6th ed, p 1089). The Motor Neuron Disease Collection of DNA and cell lines in the NINDS Repository is largely Amyotrophic Lateral Sclerosis cases (others include progressive muscular atrophy, primary lateral sclerosis, progressive bulbar palsy, Kennedy's disease). Amyotrophic lateral sclerosis (ALS) is the most common form of motor neuron disease (MND). Although ALS is the most common MND, it is still a relatively rare disease with an incidence of around 1.6 per 100,000 in the United States. It is currently incurable and treatment is largely limited to supportive care. Family history is associated with an increased risk of ALS, and many Mendelian causes have been discovered (including SOD1). However, most forms of the disease are not obviously familial. It is suspected that the sporadic forms of neurodegenerative disorders are caused by multiple genetic variants that individually make relatively weak contributions to risk. There is also an associated Control collection (see <a href="./study.cgi?study_id=phs000004.v1.p1">dbGaP</a> and <a href="http://ccr.coriell.org/Sections/Collections/NINDS/Population.aspx?PgId=194&coll=ND"> Coriell</a>). Studies in motor Neuron Disease may use cases from the NINDS repository, controls from the NINDS repository, as well as cases, and controls, from other sources. A subset of subjects from The National Institute of Neurological Disorders and Stroke (NINDS) Human Genetics Resource Center: DNA and Cell Line Repository (the NINDS Repository): Motor Neuron/Amyotrophic Lateral Sclerosis (ALS) Study was utilized in the <a href="./study.cgi?id=phs000101">Genome-wide genotyping in amyotrophic lateral sclerosis and neurologically normal controls: first stage analysis and public release of data</a> study.

Project description:The NINDS repository <a href="http://ccr.coriell.org/ninds">(http://ccr.coriell.org/ninds/)</a> was established in October 2001 with the goal of developing standardized, broadly useful diagnostic and other clinical data, as well as a collection of DNA and cell line samples to further advance gene discovery of neurological disorders. All samples and both phenotypic and genotypic data are available to the research community including academic and industry scientists. A set of samples from individuals who do not have neurological disease was felt to be essential to allow gene discovery in neurological disorders to proceed. Towards this goal, the NINDS has and is collecting samples and phenotypic data on neurologically normal individuals. The data being collected includes demographic, ethnic, and exclusion of neurological disease information. Variables were measured using the <a href="javascript:getPage('document.cgi', 43);">Control Clinical Data Elements form</a>. As of June 2007, there are a total of 2157 publicly available and an additional >2000 which will be added to the publicly available biomaterials collection shortly. Blood samples were drawn from neurologically normal, unrelated, individuals at many different sites. Spouses, convenience controls, and population controls were all included in this collection. Each participant underwent a detailed medical history interview and had no family history on specific query of Alzheimer's disease, amyotrophic lateral sclerosis, ataxia, autism, bipolar disorder, brain aneurysm, dementia, dystonia, or Parkinson's disease. Folstein Mini-mental state examination scores ranged from 26-30 and are available on a subset of individuals. All participants were interviewed for family history in detail and specifically had no first degree relative with any of the following: amyotrophic lateral sclerosis, ataxia, autism, brain aneurysm, dystonia, Parkinson's disease, and schizophrenia. A subset of neurologically normal control subjects was utilized in <a href="./study.cgi?id=phs000089">NINDS Parkinson's Disease</a>, <a href="./study.cgi?id=phs000101">NINDS Amyotrophic Lateral Sclerosis and Controls</a> and <a href="./study.cgi?id=phs000102">NINDS Ischemic Stroke Genetics Study (ISGS)</a>.

Project description:Prenatal alcohol exposure (PAE) is linked to elevated risk for systemic adult-onset diseases like hypertension, impaired glucose and immune regulation, and in animal models, to impaired recovery from acute onset diseases like cerebrovascular ischemic stroke. Recent evidence suggests that the gastrointestinal system rapidly becomes dysbiotic following cerebrovascular stroke, resulting in systemic inflammation. We hypothesized that a history of PAE would modify the systemic effects of stroke, and transduce exposure-dependent transcriptomic changes in downstream sentinel tissues of the enteric portal circulation that have previously been linked to biobehavioral outcomes in rodent PAE models. Pregnant Sprague Dawley rats were exposed to repeated episodes of vaporized ethanol or room air from gestational day 8 to 19. At 5 months, progeny from each treatment condition were subjected to unilateral endothelin-1 induced occlusion of the middle cerebral artery and outcomes evaluated after 2 days while other progeny stayed stroke-naïve. Stroke induced disabilities were assessed by behavioral assays (adhesive removal, Vibrissae evoked fore-limb placement, circling) and infarct size. The mesenteric adipose tissue and liver transcriptomes were assessed by sequencing, from age-matched stroke-exposed and stroke-naïve offspring. In stroke-naïve animals, pathway analysis identified rRNA processing as downregulated and citric acid cycle as upregulated in mesenteric adipose. Weighted gene correlation network analysis (WGCNA) identified, in the liver of stoke-naïve animals, a moderate but significant correlation between PAE status and necroptosis, a proinflammatory form of programmed cell death (Pearson’s r=0.554, p<0.05). Two days after a stroke, PAE rats exhibited worse neurological scores compared to controls (p<0.05). WGCNA after stroke identified an adipose gene network associated with B cell differentiation and NF-kappa B signaling as moderately correlated with post-stroke neurological function (Pearson's r=0.52, p=0.05). Post-stroke WGCNA also identified a liver proinflammatory gene network strongly correlated with post-stroke neurological function (Pearson's r=-0.63, p<0.01). PAE persistently alters the transcriptome of afferent tissue targets of enteric circulation in adult rat offspring. Moreover, PAE-linked enteric inflammation is correlated to worse outcomes following cerebrovascular ischemic stroke in adulthood. Enteric disturbances may mediate adverse brain health outcomes due to PAE in adulthood.
