Findings from the Human Genome Project and from Genome-Wide Association (GWA) studies indicate that many diseases and traits manifest a more complex genomic pattern than previously assumed. These findings, and advances in high-throughput sequencing, suggest that there are many sources of influence-genetic, epigenetic, and environmental. This volume investigates the role of the interactions of genes and environment (G x E) in diseases and traits (referred to by the contributors as complex phenotypes) including depression, diabetes, obesity, and substance use.

In this report, we address a scenario that uses synthetic genotype case-control data that is influenced by environmental factors in a genome-wide association study (GWAS) context. The precise way the environmental influence contributes to a given phenotype is typically unknown. Therefore, our study evaluates how to approach a GWAS that may have an environmental component. Specifically, we assess different statistical models in the context of a GWAS to make association predictions when the form of the environmental influence is questionable. We used a simulation approach to generate synthetic data corresponding to a variety of possible environmental-genetic models, including a “main effects only” model as well as a “main effects with interactions” model. Our method takes into account the strength of the association between phenotype and both genotype and environmental factors, but we focus on low-risk genetic and environmental risks that necessitate using large sample sizes (N = 10,000 and 200,000) to predict associations with high levels of confidence. We also simulated different Mendelian gene models, and we analyzed how the collection of factors influences statistical power in the context of a GWAS. Using simulated data provides a “truth set” of known outcomes such that the association-affecting factors can be unambiguously determined. We also test different statistical methods to determine their performance properties. Our results suggest that the chances of predicting an association in a GWAS is reduced if an environmental effect is present and the statistical model does not adjust for that effect. This is especially true if the environmental effect and genetic marker do not have an interaction effect. The functional form of the statistical model also matters. The more accurately the form of the environmental influence is portrayed by the statistical model, the more accurate the prediction will be. Finally, even with very large samples sizes, association predictions involving recessive markers with low risk can be poor

Disorders of the ovary can lead to a wide range of endocrinologic and malignant conditions, many of which are linked with fertility. This comprehensive, yet succinct book presents a multidisciplinary approach to address the major issues in diagnosing and managing ovarian disorders. Beginning with the complex functioning of the normal ovary, the editors address many of the major issues in women's health. New chapters on ovarian cysts, menopause, the aging ovary, early detection and risk assessment of ovarian cancer, screening, stage I ovarian cancer and many other topics have been added to this third edition. Assisted reproductive techniques, diagnostic imaging modalities, minimally invasive surgery, and chemotherapy have advanced dramatically and the chapters have been updated accordingly. This well-documented volume has been fully updated with contemporary references and chapters written by current leaders in their field. A must-read for gynecologists, oncologists, obstetricians, pathologists and researchers in human reproductive sciences.

Living with a chronic condition like hemophilia is not just a physical challenge; it impacts every aspect of life—emotional, psychological, and social. Hemophilia, a genetic disorder affecting the blood’s ability to clot properly, requires individuals to navigate a complex web of medical treatments, lifestyle adjustments, and emotional hurdles. For many, the weight of managing a genetic condition can lead to feelings of isolation, anxiety, and depression. This book, "Psychological Support by Cognitive Behavioral Therapy for Hemophilia," was written with the purpose of providing a comprehensive approach to address not only the physical but also the psychological aspects of living with hemophilia. By merging insights from genetics, biology, and psychology, particularly through the lens of Cognitive Behavioral Therapy (CBT), this book seeks to empower individuals with hemophilia to develop coping strategies, manage emotional distress, and lead fulfilling lives despite their condition. Cognitive Behavioral Therapy has been widely recognized as an effective therapeutic approach for managing a variety of mental health challenges, and it offers valuable tools for those grappling with the emotional and psychological burdens of chronic illness. This book covers essential topics such as trauma, genetic counseling, independence in one’s genetic journey, and the practical application of CBT techniques. By addressing both the biological underpinnings of hemophilia and the cognitive and emotional toll it takes, this book aims to create a balanced and supportive guide for patients, caregivers, and mental health professionals alike. In the chapters that follow, we explore the intricate connection between mind and body, offering both theoretical knowledge and practical tools to manage the emotional impact of hemophilia. From learning how to manage pain and fatigue, to developing strategies for mental resilience and emotional regulation, this book is designed to be a go-to resource for anyone affected by hemophilia. It is my hope that this book provides a source of comfort, guidance, and empowerment to those living with hemophilia, helping them to navigate their journey with greater confidence, mental fortitude, and emotional well-being.

Plant phenotyping is the thorough assessment of plant traits such as growth, development, adaptation, yield, quality, tolerance, resistance, architecture, and the basic measurement of individual quantitative parameters that form the basis for understanding of traits. Genetic approaches to understand plant growth and development have always benefitted from phenotyping techniques that are simple, rapid and measurable in units. The forward genetics approach is all about understanding the trait inheritance using the phenotypic data and in most cases it is the mutant phenotypes that formed the basis for understanding of gene functions. With rapid advancement of genotyping techniques, high throughput genotyping has become a reality at costs people never imagined to be that low, but the phenotypic methods did not receive same attention. However, without quality phenotyping data the genotyping data cannot be effectively put to use in plant improvement. Therefore efforts are underway to develop high-throughput phenotyping methods in plants to keep pace with revolutionary advancement in genotyping techniques to enhance the efficiency of crop improvement programs. Keeping this in mind, we described in this book the best phenomic tools available for trait improvement in some of the world’s most important crop plants.

Genetic epidemiology plays a key role in discovering genetic factors influencing health and disease, and in understanding how genes and environmental risk factors interact. There is growing interest in this field within public health, with the goal of translating the results into promoting health and preventing disease in both families and populations. This textbook provides graduate students with a working knowledge of genetic epidemiology research methods. Following an overview of the field, the book reviews key genetic concepts, provides an update on relevant genomic technology, including genome-wide chips and DNA sequencing, and describes methods for assessing the magnitude of genetic influences on diseases and risk factors. The book focuses on research study designs for discovering disease susceptibility genes, including family-based linkage analysis, candidate gene and genome-side association studies, assessing gene-environment interactions and epistasis, studies of Non-Mendelian inheritance, and statistical analyses of data from these studies. Specific applications of each research method are illustrated using a variety of diseases and risk factors relevant to public health, and useful web-based genetic analysis software, human reference panels, and repositories, that can greatly facilitate this work, are described.
