Genetic disease contributes to a major portion of our health care costs. While most of the human genetic burden is transmitted from generation to generation, environmental chemicals capable of reacting with germ cell DNA could produce new mutations, resulting in an even greater genetic liability for the next generation. The potential impact of environmental mutagens on the health and viability of other living things is important to consider as well. Methods for Genetic Risk Assessment features contributions from international experts to provide a comprehensive review of the current status of genetic risk assessment. You'll learn about various methods and strategies for when and how to conduct genetic risk assessments on human populations. You will also learn about the potential effects of environmental genotoxins on nonhuman organisms.

New Trends in Genetic Risk Assessment is based on the Fifth International Round Table of the Rhône-Poulenc Santé Foundation, held in Nice 1987. The conference was an attempt to review the latest theories and mechanisms stipulated for the various aspects of genotoxicity; it was above all an open forum to discuss the new trends, the new tests, and the new battery of tests for assessing the genetic risk of chemicals and especially drugs. This volume is actually not a proceedings of the meeting but a monograph specially edited to report the reviews which were presented and the discussions which took place; it was designed to provide a better understanding of the knowledge obtained in the most recent years and to help in the practical choice of approaches or tests for the prediction of the various forms of genotoxicity. The main subjects of this review concern molecular analysis of mutagenesis, detection of DNA damage, gene mutation, clastogenesis, aneuploidy, and germ cells. Each theme is preceded by a short overview summarizing the state of the art and the contributions of each author. Finally, special attention was given to the personal views of some leading toxicologists as to the battery of tests presently available or recommended.

This eBook contains the 19 articles that were part of a Special Topic in Frontiers in Genetics entitled “Genetics Research in Electronic Health Records Linked to DNA Biobanks”. The Special Issue was published on-line in 2014-2015 and contained papers representing the diverse research ongoing in the integration of electronic health records (EHR) with genomics through basic, clinical, and translational research. We have divided the eBook into four Chapters. Chapter 1 describes the Electronic Medical Records and Genomics (eMERGE) network and its contri-bution to genomics. It highlights methodological questions related to large data sets such as imputation and population stratification. Chapter 2 describes the results of genetic studies on different diseases for which all the phenotypic information was extracted from the EHR with highly specific ePhenotyping algorithms. Chapter 3 focuses on more complex analyses of the genome including copy number variants (CNV), pleiotropy com-bined with phenome-wide association studies (PheWAS), and epistasis (gene-gene interactions). Chapter 4 discusses the use of genetic data together with EHR-derived clinical data in clinical settings, and how to return genetic results to patients and providers. It also contains a comprehensive review on genetic risk scores. We have included mostly Original Research Articles in the eBook, but also Reviews and Methods papers on the relevant topics of analyzing and integrating genomic data. The release of this eBook is timely, since several countries are launching Precision Medicine initiatives. Precision Medicine is a new concept in patient care taking into account individual variability in genetic, environmental and lifestyle factors, when treating diseases or trying to prevent them from developing. It has become an important focus for biomedical, clinical and translational informatics. The papers presented in this eBook are well positioned to educate the readers about Precision Medicine and to demonstrate the potential study designs, methods, strategies, and applications where this type of research can be performed successfully. The ultimate goal is to improve diagnostics and provide better, more targeted care to the patient.
