Genetic Testing For Developmental Disabilities Intellectual Disability And Autism Spectrum Disorder Technical Brief Number 23

This Technical Brief collects and summarizes information on genetic tests clinically available in the United States to detect genetic markers that predispose to DDs. It also identifies, but does not systematically review, existing evidence addressing the tests' clinical utility. This Brief primarily focuses on patients with idiopathic or unexplained DDs, particularly intellectual disability, global developmental delay, and autism spectrum disorder. Several better-defined DD syndromes, including Angelman syndrome, fragile X syndrome, Prader-Willi syndrome, Rett syndrome, Rubinstein-Taybi syndrome, Smith-Magenis syndrome, velocardiofacial syndrome, and Williams syndrome are also included. Patient-centered health outcomes (e.g., functional or symptomatic improvement) and intermediate outcomes (e.g., changes in clinical decisions or family reproductive decisions, the tests' diagnostic accuracy and analytic validity) are examined.

According to the CDC "about one in six, or about 15%, of children aged 3 through 17 years have one or more developmental disabilities," such as ADHD, autism spectrum disorders, cerebral palsy, intellectual disability, and learning disability. Intellectual disorders are characterized by significant limitations in both intellectual functioning and in adaptive behavior, which covers many everyday social and practical skills, impacting learning, reasoning, problem solving, and other cognitive processes. These disabilities originate before the age of 18 and continue across the life span. Developmental disorders are chronic disabilities that can be cognitive or physical or both. The disabilities appear before the age of 22 and are likely to progress across the lifespan. Some developmental disorders are largely physical issues, such as cerebral palsy or epilepsy. Some individuals may have a disorder that includes a physical and intellectual disability; for example, Down syndrome or fetal alcohol syndrome. Intellectual and developmental disorders are significant and growing issues that are studied across a number of disciplines. The SAGE Encyclopedia of Intellectual and Developmental Disorders is aimed at students interested in psychology, counseling, education, social work, psychiatry, health sciences, and more. This encyclopedia will provide an in-depth look at a wide range of disorders, alongside interventions, the latest research translated for an undergraduate audience, historical context, and assessment tools for higher-level students. We will take a truly interdisciplinary approach by also covering sociocultural viewpoints, policy implications, educational applications, ethical issues, and more.

This book is open access under a CC BY 4.0 license. ​This handbook synthesizes and analyzes the growing knowledge base on life course health development (LCHD) from the prenatal period through emerging adulthood, with implications for clinical practice and public health. It presents LCHD as an innovative field with a sound theoretical framework for understanding wellness and disease from a lifespan perspective, replacing previous medical, biopsychosocial, and early genomic models of health. Interdisciplinary chapters discuss major health concerns (diabetes, obesity), important less-studied conditions (hearing, kidney health), and large-scale issues (nutrition, adversity) from a lifespan viewpoint. In addition, chapters address methodological approaches and challenges by analyzing existing measures, studies, and surveys. The book concludes with the editors’ research agenda that proposes priorities for future LCHD research and its application to health care practice and health policy. Topics featured in the Handbook include: The prenatal period and its effect on child obesity and metabolic outcomes. Pregnancy complications and their effect on women’s cardiovascular health. A multi-level approach for obesity prevention in children. Application of the LCHD framework to autism spectrum disorder. Socioeconomic disadvantage and its influence on health development across the lifespan. The importance of nutrition to optimal health development across the lifespan. The Handbook of Life Course Health Development is a must-have resource for researchers, clinicians/professionals, and graduate students in developmental psychology/science; maternal and child health; social work; health economics; educational policy and politics; and medical law as well as many interrelated subdisciplines in psychology, medicine, public health, mental health, education, social welfare, economics, sociology, and law.

Recent years have seen spectacular advances in the field of circadian biology. These have attracted the interest of researchers in many fields, including endocrinology, neurosciences, cancer, and behavior. By integrating a circadian view within the fields of endocrinology and metabolism, researchers will be able to reveal many, yet-unsuspected aspects of how organisms cope with changes in the environment and subsequent control of homeostasis. This field is opening new avenues in our understanding of metabolism and endocrinology. A panel of the most distinguished investigators in the field gathered together to discuss the present state and the future of the field. The editors trust that this volume will be of use to those colleagues who will be picking up the challenge to unravel how the circadian clock can be targeted for the future development of specific pharmacological strategies toward a number of pathologies.

Autism spectrum disorders are developmental disorders. Individuals with autism spectrum disorders develop differently. These differences are usually present in social interaction, communication, and sensory processing, and become visible through a wide variety of behavioral responses that differ from individuals without autism spectrum disorders. Despite significant research efforts, the exact causes of autism spectrum disorders remain poorly understood; however, researchers have gained extensive insights into possible pathomechanisms, even at the molecular level of cells. Many diagnostic criteria have been developed, adapted, and improved. The eight chapters in this book highlight the current state-of-the-art in many areas of autism spectrum disorders. Chapter 1 provides an overview of the epidemiology of autism spectrum disorders and the current knowledge of the underlying pathogenic mechanisms. Chapter 2 summarizes the diagnostic criteria and procedures and highlights present and upcoming therapeutic strategies. Chapter 3 reviews the adverse events and trauma in people with autism spectrum disorders. Chapters 4 and 5 focus on atypical sensory processing, and Chapter 6 discusses the genetic overlap of autism spectrum disorders with other neuropsychiatric disorders such as attention deficit hyperactivity disorder (ADHD), depression, and schizophrenia. Chapter 7 focuses on the contribution of abnormalities in mitochondria, and chapter 8 discusses gut-brain interactions and a potential role for microbiota in autism spectrum disorders. This book is aimed primarily at clinicians and scientists, but many areas will also be of interest to the layperson.

This book is a printed edition of the Special Issue "The Identification of the Genetic Components of Autism Spectrum Disorders 2017" that was published in IJMS

Neurodevelopmental diseases affect three percent of children and the specific cause is difficult to determine in many cases. Genetic research uncovered many loss or gain of function mutations in genes that are associated with synaptic development and or remodeling. However, more an more data are accumulating regarding the importance in gene regulations in neurodevelopmental diseases. Thjis issue addresses many aspects of the genomics of neurodevelopmental diseases, including articles devoted to genomic variations of brain malformations; neuroimaging of brain development; update on autism evaluation and genetics; prader-willi and angelman syndromes; tuberous sclerosis complex; genetics of pediatric epilepsy; pediatric leukodystrophies; autoimmune encephalopathies; inherited neuropathies and motor neuron diseases; and muscular dystrophies and congenital myopathies.
