Book Description
Gene Environment Interactions: Nature and Nurture in the Twenty-first Century offers a rare, synergistic view of ongoing revelations in gene environment interaction studies, drawing together key themes from epigenetics, microbiomics, disease etiology, and toxicology to illuminate pathways for clinical translation and the paradigm shift towards precision medicine. Across eleven chapters, Dr. Smith discusses interactions with the environment, human adaptations to environmental stimuli, pathogen encounters across the centuries, epigenetic modulation of gene expression, transgenerational inheritance, the microbiome's intrinsic effects on human health, and the gene-environment etiology of cardiovascular, metabolic, psychiatric, behavioral and monogenic disorders. Later chapters illuminate how our new understanding of gene environment interactions are driving advances in precision medicine and novel treatments. In addition, the book's author shares strategies to support clinical translation of these scientific findings to improve heath literacy among the general population. Offers a thorough, interdisciplinary discussion on recent revelations from gene environment interaction studies Illuminates environmental factors affecting disease-gene etiology and treatment Supports the clinical translation of gene environment interaction findings into novel therapeutics and precision medicine

Book Description
Neurodevelopmental disorders (NDDs) are severe, heritable conditions characterized by impaired brain development and disability in cognition, social interaction and behavior. Genetic predisposition appears to interact with environmental factors to produce the onset of the disease. In the last decade genomic analysis on NDDs advanced the knowledge of the genetic causes of these disorders: most of the genes identified were not predicted from known biology, and almost all of them engage in neurodevelopmental processes. However, the same studies revealed an unexpected outcome regarding the molecular etiology: many of the same susceptibility genes as well as molecular pathways are emerging across hitherto unrelated disorders- such as autism and schizophrenia- challenging how we conceptualize these conditions. These new discoveries call for the establishment of additional criteria for the classification of the genes and related phenotypes. Beyond the classical distinction according to diagnostic criteria, new parameters should be taken into account: the genetics, the neurobiology of the gene products and the molecular mechanisms that they control. Our broad understanding of NDDs, requires a combination of approaches, including human studies, animal models and theoretical computation. Indeed, progress in technology and the generation of accurate models are advancing the field, and the research is rapidly growing. This Research Topic presents recent advances in neurodevelopmental disorders from genes to systems, in single conditions and across different phenotypes, and report the newest treatments in use. Recognized experts in the field discuss recent findings in molecular studies, in vivo imaging, neuropsychology, neuropharmacology and computational neuroscience. This multidisciplinary approach enriches our understanding of the mechanisms involved in the onset and progression of NDDs with the perspective of revealing the biological signs of the disorders and identifying new therapeutics.

This book covers a wide array of topics relevant to behavioral genetics from both a preclinical and clinical standpoint. Indeed in juxtaposing both areas of research the reader will appreciate the true translational nature of the field. Topics covered range from technical advances in genetic analysis in humans and animals to specific descriptions of advances in schizophrenia, attention disorders, depression and anxiety disorders, autism, aggression, neurodegeneration and neurodevelopmental disorders. The importance of gene-environment interactions is emphasised and the role of neuroimaging in unravelling the functional consequences of genetic variability described. This volume will be valued by both the basic scientist and clinician alike who may use it as a detailed reference book. It will also be of use to the novice to the field, to whom it will serve as an in-depth introduction to this exciting area of research.

Book Description
Schizophrenia is a multi-factorial disease characterized by a high heritability and environmental risk factors (e.g. stress and cannabis use). In recent years, an increasing number of researchers worldwide have started investigating the ‘two-hit hypothesis’ of schizophrenia predicting that genetic and environmental risk factors interactively cause the development of the disorder. This work is starting to produce valuable new animal models and reveal novel insights into the pathophysiology of schizophrenia. Eventually, it might help advance studies of the molecular pathways involved in this mental disorder and propose more specific molecular medicine. However, the complexity of this multi-factorial line of research has also caused difficulties in data interpretation and comparison. Our research topic is intended to cover past and current directions in research dedicated to the understanding and measurement of gene-environment interactions (GxE) in schizophrenia, the neurobiological and behavioural consequences of such interactions as well as the challenges and limitations one encounters when working on complex aetiological systems.

Book Description
Autism Spectrum Disorder is a complex neurodevelopmental disorder which is often associated with increased anxiety and deficits in cognitive ability. The present research investigated a potential gene*environment interaction between two factors previously implicated in ASD in a rat model; prenatal exposure to valproate (VPA) and genetic reduction of the serotonin transporter (SERT). Wildtype and heterozygous SERT knockout rats prenatally exposed to VPA or saline on gestational day12.5 (G12.5) were assessed on measures of anxiety: elevated plus-maze and novelty suppressed-feeding and cognitive ability: prepulse inhibition and latent inhibition. A significant main effect was found for VPA exposure in all paradigms, showing increased anxiety-typical behaviour and abnormal cognitive ability. However, no significant effect of genotype or interaction was observed. Results from the present study do not confirm gene*environment interaction between prenatal VPA and heterozygous SERT knockout but this may be due to several factors that are discussed within the thesis. In any case, this study represents a starting point for further studies investigating other combinations of genetic and environmental factors as models of ASD pathogenesis.

Book Description
Bringing together foremost experts, this book reviews groundbreaking gene–environment research and explores implications for clinical practice, prevention, and public policy. Presented is cutting-edge work on the interplay of genetic factors and childhood experiences in the development of mental disorders such as depression, conduct disorder, and schizophrenia. Essential topics include what scientists currently know about "susceptibility genes"; the mechanisms by which maltreatment and other stressors interact with biological susceptibilities across development; and factors that make certain children more resilient than others. Future directions for personalizing treatment and prevention efforts, thus making them more effective, are discussed.

Book Description
This book examines the current research in gene-environment transactions (GEX) and its potential use in developing interventions and applications tailored to individual genetic makeups. Key concepts underlying GEX studies in this area are defined, identifying fundamental challenges in devising informed research questions and conducting valid and useful experiments. Chapters analyze GEX models inspired by the present day genome-based frameworks, particularly in terms of advances in identifying and understanding complex environmental factors, using examples from common psychological conditions, such as antisocial behavior, chronic physical aggression, and chronic internalizing disorder. In addition, the book presents new and potential applications of the framework in the contexts of prevention science and intervention research. Topics featured in this book include: Epigenetics and the biology of gene x environment interactions. Gene by environment interactions and its potential use for intervention strategies in anxiety disorders. The challenges and potential for research on gene-environment interactions within autism spectrum disorder. Using genetically informed prevention trials to test gene x environment hypothese. Challenges for intervention research within the GEX framework. Gene-Environment Transactions in Developmental Psychopathology is a must-have resource for researchers/professors, clinicians, and related professionals as well as graduate students in developmental psychology, psychiatry, human genetics, and related disciplines.
