Characterization of the genetic landscape of Alzheimer's disease (AD) and related dementias (ADD) provides a unique opportunity for a better understanding of the associated pathophysiological processes. We performed a two-stage genome-wide association study totaling 111,326 clinically diagnosed/'proxy' AD cases and 677,663 controls. We found 75 risk loci, of which 42 were new at the time of analysis. Pathway enrichment analyses confirmed the involvement of amyloid/tau pathways and highlighted microglia implication. Gene prioritization in the new loci identified 31 genes that were suggestive of new genetically associated processes, including the tumor necrosis factor alpha pathway through the linear ubiquitin chain assembly …

The effectiveness of artemisinin-based combination therapies (ACTs) depends not only on that of artemisinin but also on that of partner molecules. This study aims to evaluate the prevalence of mutations in the Pfdhfr, Pfdhps, and Pfmdr1 genes from isolates collected during a clinical study. Plasmodium genomic DNA samples extracted from symptomatic malaria patients from Dogondoutchi, Niger, were sequenced by the Sanger method to determine mutations in the Pfdhfr (codons 51, 59, 108, and 164), Pfdhps (codons 436, 437, 540, 581, and 613), and Pfmdr1 (codons 86, 184, 1034, and 1246) genes. One hundred fifty-five (155) pre-treatment samples were …

For Whom The Bell Tolls: Psychopathological And Neurobiological Correlates Of The Dna Methylation Index Of Time-To-Death, Sage E. Hawn, Xiang Zhao, Danielle R. Sullivan, Mark Logue, Dana Fein-Schaffer, William Milberg, Regina Mcglinchey, Mark W. Miller, Erika J. Wolf

Psychology Faculty Publications

Psychopathology is a risk factor for accelerated biological aging and early mortality. We examined associations between broad underlying dimensions of psychopathology (reflecting internalizing and externalizing psychiatric symptoms), PTSD, and age-adjusted GrimAge (“GrimAge residuals”), a DNA methylation biomarker of mortality risk relative to age. We also examined neurobiological correlates of GrimAge residuals, including neurocognitive functioning, blood-based biomarkers (of inflammation, neuropathology, metabolic disease), and cortical thickness. Data from two independent trauma-exposed military cohorts (n = 647 [62.9% male, M_age = 52], n = 434 [90% male, M_age = 32]) were evaluated using linear regression models to test associations between …

Evaluating A Test For Shedding Propensity Using Tape Lifts From Different Skin Locations, Xiao M. Chen

Student Theses

The shedding propensity of a person can assist data interpretation in casework when assessing the possibility of passive transfer for DNA analysis. Past studies on shedding propensity evaluated palmar skin (washed and unwashed) deposits. This study compared different skin locations with respect to shedding propensity, and explored the potential of tape-lifts as a skin surface collection method. Eight different skin types and samples were collected with adhesive tape disks from 28 participants over three non-consecutive days; the washed and unwashed fingers from both hands, toe, and arm, neck below ear, and nape. Samples were extracted, quantified, amplified, genotyped, and evaluated …

Otoliths Of South-Western Australian Fish: A Photographic Catalogue, Chris Dowling, Kim Smith, Elaine Lek, Joshua Brown

Fisheries Research Reports

Due to the species-specific nature of otoliths and given they are often the only part of the fish preserved when fish die, otolith catalogues can be used in numerous applications, such as diet studies in fish eating animals, including pinnipeds, fish and sea birds; archaeological purposes such as reconstructing indigenous people’s diets from otoliths found in middens or evolutionary history of fish species by comparing fossilized otoliths. Given the unique mixture of subtropical and temperate fish, including many endemic species that occur off the southwest corner of WA having a catalogue for this area is extremely important for people working …

Informed Consent: Foundations And Applications, Joanna Smolenski

Dissertations, Theses, and Capstone Projects

Since its advent in the 20th century, informed consent has become a cornerstone of ethical healthcare, and obtaining it a core obligation in medical contexts. In my dissertation, I aim to examine the theoretical underpinnings of informed consent and identify what values it is taken to protect. I will suggest that the fundamental motivation behind informed consent rests in something I’ll call bodily self-sovereignty, which I argue involves a coupling of two groups of values: autonomy and non-domination on the one hand, and self-ownership and personal integrity on the other. I will then go on to consider two 'case …

Having A High-Activity Catechol-O-Methyltransferase Allele Is Associated With Elevated Anxiety And Lower Salivary Dehydroepiandrosterone But Also Lower Alpha Amylase In Children With Chromosome 22q11.2 Deletion Syndrome., Jessie Beebe

LSU New Orleans Theses and Dissertations

Chromosome 22q11.2 deletion syndrome (22q11.2DS) results from a hemizygous deletion located on the long arm of chromosome 22. The most common deletion sizes affect between 30 and 90 genes. Individuals with 22q11.2DS may develop serious developmental and psychiatric disorders. The phenotype is highly variable, however, and may be influenced by allelic variation of the retained copies of genes covered by the deletion. I set out to examine the effects of two genes, catechol-O-methyltransferase (COMT) and proline dehydrogenase (PRODH), in relation to anxiety in children and adolescents with 22q11.2DS. Individuals with the major COMT allele (higher activity) have significantly higher anxiety …

Patterns Of Recent Natural Selection On Genetic Loci Associated With Sexually Differentiated Human Body Size And Shape Phenotypes, Audrey M. Arner, Kathleen E. Grogan, Mark Grabowski, Hugo Reyes-Centeno, George H. Perry

Anthropology Faculty Publications

Levels of sex differences for human body size and shape phenotypes are hypothesized to have adaptively reduced following the agricultural transition as part of an evolutionary response to relatively more equal divisions of labor and new technology adoption. In this study, we tested this hypothesis by studying genetic variants associated with five sexually differentiated human phenotypes: height, body mass, hip circumference, body fat percentage, and waist circumference. We first analyzed genome-wide association (GWAS) results for UK Biobank individuals (~194,000 females and ~167,000 males) to identify a total of 114,199 single nucleotide polymorphisms (SNPs) significantly associated with at least one of …

Influence Of Drd4 Receptor Gene Polymorphism On Aspirational Quality And Approach Motivation, Harry Henry-Ojo

ATU Theses and Dissertations 2021 - Present

The present study investigates the presence of a molecular genetic basis of the quality of aspiration and motivation for behavior described by Ryan and Deci’s self-determination theory and Gray’s biopsychological theory of personality respectively. In this study, investigation was carried out to determine the impact of DRD4 receptor gene polymorphism on intrinsic and extrinsic aspiration as well as approach motivation using the Aspiration Index scales and Behavioral Inhibition and Activation (BIS/BAS) scales as our psychometric instrument of evaluation. In a pilot study consisting of 9 healthy subjects, the 7R allele of DRD4 receptor gene was associated with higher mean score …

The Role Of Placental Genes On Intellectual Disability And Developmental Delay, Maedot A. Yidenk

Dissertations, Theses, and Capstone Projects

The complex interaction between gene expressions and environmental factors plays a key role in the pathogenesis of various diseases, including neurodevelopmental disorders (Lenroot & Giedd, 2008). This study aimed to evaluate first, the magnitude of association between placental gene Methyl-CpG Binding Protein 2 (MeCP2) and intellectual disability (ID) in the offspring and second, the synergy between placental gene Forkhead box protein 1(FOXP1) and developmental delay (DD) in the offspring. We focused on assessing two specific paradigms, i) placental gene expressions of MeCP2 among children that have ID vs. children without ID; and ii) placental gene expression of …

Detecting Bacterial Species From Ancient Human Skeletal Samples, Ariel Owens, Daisy Mcgrath, Tsai-Tien Tseng

Symposium of Student Scholars

This paleopathological study aims to identify Mycobacterium tuberculosis complex (MTBC), Mycobacterium avium complex (MAC) and other Mycobacterium species in silico from skeletal samples that belonged to 28 Polish individuals in the Neolithic period under PRJNA422903 from the Sequence Read Archive (SRA). After next-generation sequencing (NGS), bioinformatics methods are heavily relied upon for identification of pathogens from complex samples. We implemented a bioinformatics pipeline, with custom-built databases, utilizing the following software tools: Trim Galore! and Kraken2. After adapter trimming, Kraken2 was used for taxonomic classifications. We have found that Mycobacterium is present in all 28 individuals. The average percentage of MAC …

Extraction Of Human Dna From Soil In A Simulated Clandestine Grave, Arely Joaly Parra Lopez

Honors Theses

Locard’s Exchange Principle states that “every contact leaves a trace.” The same principle applies when a perpetrator of a homicide decides to bury a victim in a clandestine grave. If a perpetrator originally buried a murder victim in haste to prevent discovery and then decided to later move the victim’s body to a remote location for disposal, decomposition fluids from the victim’s body (which contain cellular material and therefore DNA) would remain in the surrounding grave soil at the original burial site. It is possible that investigators could: 1) prove that a human body had once laid in that location …

Big Five Personality Traits And Political Orientation: An Inquiry Into Political Beliefs, Ian E. Phillips

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

Personality research centered on the Big Five personality traits has heavily impacted our understanding in regards to what forces orient a person on a political spectrum. Examining how personality differences interact with political orientation, this research seeks to provide information on what makes someone either more or less likely to be liberal or conservative based on their temperament. In this paper, previous personality research is synthesized into one discussion, centered on what the effects of each trait are and how they impact political orientation, the heritability of personality, and what implications there are for such research in the realm of …

Assessing Genetic Counselors' Clinical Approach And Practices Regarding Pathogenic/Likely Pathogenic Variant Downgrades, Grant Bonesteele

Dissertations and Theses (Open Access)

Although rare, variant downgrades from a pathogenic/likely pathogenic (P/LP) variant to a variant of uncertain significance can have a significant impact on patients and their families in the clinical cancer setting. However, there is a lack of literature about how to approach these potentially challenging cases as a genetic counselor. Therefore, we aimed to characterize genetic counselors’ experiences, approach, and practices to variant downgrade cases using an online survey. The survey asked participants how they would approach variant downgrade scenarios involving the CDH1 or ATM genes with variable family histories. Genetic counselors appear to be united in whether they would …

Determination Of Human Shedding Propensity Based On Str Results, Genevieve Trapani

Student Theses

Trace DNA evidence may be discovered at a crime scene after having been deposited by a person of interest via active or passive transfer. Based on previous studies, passive transfer of one’s DNA is influenced by their shedding propensity, or probability of depositing a detectable amount of DNA through touch. Determining the shedding propensity of a person of interest can aid in trace DNA interpretation in forensic casework. This study explored STR profile quality and the presence of a DNA mixture for different skin surface locations, including fingertips before and after handwashing. As expected, unwashed fingers showed a higher prevalence …

Evaluating Insurance Approval Rates Of Exome Sequencing And Its Effect On Minority Patients' Access To Genetic Care, Katlyn Frane

Dissertations and Theses (Open Access)

Exome sequencing (ES) is often a standard step in the genetic testing process for patients with rare or complex disease. Despite clinical implementation of ES, insurance companies (payers) continue to deny this test. We investigated if the payer barrier is influenced by payer type, and if other demographic or clinical information correlated to ES approval and obtainment. To do this, a retrospective chart and clinical database review was completed on patients seen at a tertiary care center and community-based clinic. Patient demographics, clinical indications, and testing recommendations and outcomes were used to assess ES approval and obtainment. We found that …

The Genetic Links Between Archaic And Modern Humans, Maria J. Orellana Rosales

Thinking Matters Symposium

Our modern physiology is the mixture of many archaic humans that once roamed our planet. The evidence of these archaic humans is still present in our DNA. This poster reviews how our understanding of ancient human genetics has drastically changed due to advances in molecular genetics. Neanderthal and Denisovan remains have been sequenced for nuclear and mitochondrial DNA. Neanderthal and Denisovan genetic ancestry have been identified by genomic studies in modern human populations across Eurasia and Pacific Island regions. Studies have shown a gene flow of 4±1% from Neanderthals to present-day Eurasians. Whereas, Papuan and Melanesian individuals share 4±0.7% more …

Genetically Modified Organisms Are Important But Also Controversial, Masen Pelletier

Thinking Matters Symposium

Genetically modified organisms (GMOs) are organisms containing a set or multiple sets of genes that have been introduced into the organism using laboratory techniques. In the instance of agriculture, the genes introduced provide advantages for the farmer and consumer by yielding plants that produce greater yields, longer growing seasons, longer shelf lives, greater concentrations of vitamins or add additional vitamins that are novel to the plant. There are two general ways that GM (genetically modified) crops are produced: the addition or removal of genes. This review focuses on an example of each strategy. An example of the latter is GM …

Attitudes And Opinions About Direct-To-Consumer Genetic Testing In Undergraduate Science Students, Morgan N. Driver, Sally I-Chun Kuo, Olivia Nayeri, Chloe J. Walker, Chelsea Derlan Willians, Tricia Smith, Amy E. Adkins, Danielle M. Dick

Graduate Research Posters

Background: There has been exponential growth in the number of direct-to-consumer genetic testing kits sold in the past decade. Consumers utilize direct-to-consumer genetic tests for a number of reasons which include learning about one’s ancestry and potential ways to manage health. Emerging adults tend to be early adopters of new technologies; however, there has been little research regarding the opinions about direct-to-consumer genetic testing in emerging adults.

Methods: Data came from a study conducted in an upper-level biology course focusing on understanding undergraduate science students’ overall experiences with receiving personalized genetic testing results from 23andMe. The present study used data …

Principal Components Analysis Corrects Collider Bias In Polygenic Risk Score Effect Size Estimation, Nathaniel S. Thomas, Peter B. Barr, Fazil Aliev, Sally I. Kuo, Danielle M. Dick, Jessica E. Salvatore

Graduate Research Posters

BACKGROUND: Genome-wide polygenic scoring has emerged as a way to predict psychiatric and behavioral outcomes and identify environments that promote the expression of genetic risks. An increasing number of studies demonstrate that the effects of polygenic risk scores (PRS) may be biased by the inclusion of heritable environments as covariates when the environment is influenced by unmeasured confounding variables, an example of collider bias. Inclusion of the principal components of observed confounders as covariates may correct for the effect of unmeasured confounders.

METHODS: A simulation study was conducted to test principal components analysis (PCA) as a correction for collider bias. …

Faculty, Staff and Student Publications

Variation in levels of the human metabolome reflect changes in homeostasis, providing a window into health and disease. The genetic impact on circulating metabolites in Hispanics, a population with high cardiometabolic disease burden, is largely unknown. We conducted genome-wide association analyses on 640 circulating metabolites in 3,926 Hispanic Community Health Study/Study of Latinos participants. The estimated heritability for 640 metabolites ranged between 0%-54% with a median at 2.5%. We discovered 46 variant-metabolite pairs (p value < 1.2 × 10

Dietary Development And Nutritional Ontogeny In Gorilla Beringei : A Multi-Layered, -Omics Approach, Emma C. Cancelliere

Dissertations, Theses, and Capstone Projects

In species who consume folivorous diets, immature individuals must contend with the challenges of extracting nutrients from fibrous foods before dietary adaptations and strategies are fully developed. Additionally, immatures have distinct nutritional needs to support their stage-specific metabolic and biophysiological requirements. To meet these stage-specific needs, while constrained by underdeveloped feeding strategies and digestive capacities, immatures may adopt distinct diets better suited to their specific developmental context. However, where dietary modification is constrained by low dietary diversity or landscape homogeneity, it is unclear how immature individuals compensate through alternative strategies. In turn, little is known about the nutritional and life …

Microrna Gene Expression States Underlying Individual Variation In Aging And Lifespan In Isogenic C. Elegans, Holly Kinser

McKelvey School of Engineering Graduate Student Theses & Dissertations

Average lifespan differs greatly between species, but lifespan among same-species individuals is also highly variable. While much effort has been devoted to uncovering longevity-associated traits and lifespan-extending perturbations in humans and model organisms, how differences in lifespan arise between individuals is unknown. Studies of human identical twins demonstrate that surprisingly little of the variation in lifespan between individuals can be explained by genetics and shared environment. Furthermore, even genetically identical C. elegans reared in highly homogeneous environments display a degree of variability in lifespan similar to that of outbred human populations. Thus, longevity must be determined at least in part …

Discrimination Of Monozygotic Twins Using Dna Methylation Levels Of One Cpg Site At Chromosome 3, Dino O. Robinson

Student Theses

Conventional STR typing, commonly used in forensics for human identification, poses a problem in criminal cases and paternity disputes involving monozygotic (MZ) twins because they share identical DNA sequences. To date, no routine method is available in forensics to differentiate between individuals of MZ pairs. Recently, epigenetic methods measuring differential DNA methylation patterns have been applied to MZ twin differentiation. In this study, we investigated the potential to identify MZ twins using a previously identified DNA methylation site in chromosome 3, cg18562578, in a sample of 129 MZ and 37 dizygotic (DZ) twin pairs. We used bisulfite converted saliva DNA …

A Review Of The Characteristics Of Super-Utilizers And Evidence-Based Approaches To Reduce Healthcare Utilization, Suswara Mandala Rayabandla

Capstone Experience: Master of Public Health

A significant fraction of health care resources in the United States of America is utilized by a comparatively small number of people. An examination of the attributes and patterns and associated evidence-based interventions for such high-utilizing patients might aid clinicians to improve interventions to address the distinctive needs of these patients, decrease their risks for numerous hospitalizations, and contribute to reducing the costs. This study aims at exploring the existing literature on the characteristics of super-utilizers and interventions to reduce avoidable use of health care among this population. The method used for this research is a comprehensive literature review. Search …
