The field of Mitochondrial Medicine has been dominated by symptom constellation-based diagnostic categorization since the first clinical syndrome was described three decades ago. Now, as rapidly expanding knowledge has revealed that mitochondrial diseases may result from several hundred distinct gene disorders with extensive clinical and mutation heterogeneity, the most useful guide for clinical care and research embraces a gene-centric approach to each individual’s disorder. Together with international colleagues, Dr. Marni Falk has developed the Mitochondrial Disease Sequence Data Resource (MSeqDR), an online, community curated, centralized data resource of mitochondrial disease data from a genomic perspective. MSeqDR provides tens of thousands of users with interactive access to mitochondrial disease feature descriptions in a defined human phenotype ontology, mitochondrial proteome-based gene and variant curation, and a suite of easily accessible tools to facilitate analysis of complex genomic datasets in nuclear and mitochondrial genomes as well as accurate interpretation of mitochondrial disease genes, variants, and diseases. Here, in the Mitochondrial Disease Genes Compendium, Dr. Marni Falk and a team of international experts have built off their work on MSeqDR to provide an all-in-one, readily accessible, and easy-to-use at point of care reference on mitochondrial disease from a gene-based perspective. In this book, clinicians and researchers will find a complete overview of mitochondrial disease genes relevant across all specialties, cataloging and building context around clinical features and the genetic basis of each condition. Within, each "gene page" offers an in-depth, referenced view of the relevant clinical disease spectrum, including gene and protein descriptions, year discovered, inheritance pattern(s), age ranges affected, major clinical features and severity range, clinical pearls, known therapies, available support groups, animal models, and gene-specific basic, translational, or clinical research activities now underway. Links provided on each gene page direct readers to MSeqDR for new findings, up-to-date genomic variant data, and user friendly informatics tools accessible to general clinicians and sophisticated geneticists or bioinformaticians alike, ensuring access to updated information on each condition. Covering 256 mitochondrial disease genes that have been expert-curated to assure they cause human diseases and have known mitochondrial localization or impact mitochondrial function, the Mitochondrial Disease Genes Compendium is directed at clinicians and researchers, facilitating bedside access to high-level, curated knowledge on mitochondrial disease genetics that rapidly enables patient diagnosis, counseling, management, treatment, and research. Provides a readily intelligible, all-in-one reference of known mitochondrial disease genes and their associated conditions Features live links to Mitochondrial Disease Sequence Data Resource (MSeqDR) pages with regularly updated genetic variant data and bioinformatics tools Covers the inheritance patterns, age spectrum affected, major clinical features, therapeutics, support groups, and research currently under way for over 250 mitochondrial diseases

This collection of reviews and protocols provides the reader with an introduction to the current state of knowledge on how various diseases are related to mitochondrial dysfunction. Mitochondria contain their own genome, a small, circular double-stranded DNA (mtDNA), and alterations in mtDNA may play an important role in the multistep carcinogenesis of at least some types of human cancer. In addition to mutations of mtDNA, many mitochondrial syndromes are due to abnormalities in nuclear genes related to oxidative phosphorylation (OXPHOS). Mitochondrial tRNA (MTT) gene mutations are an important cause of human morbidity and are associated with a wide range of pathology, from isolated organ?]specific diseases such as myopathy or hearing loss, to multisystem disorders with encephalopathy, gastrointestinal dysmotility, and life?]threatening cardiomyopathy. The relationship of the mitochondrion organelle to aging and longevity is also discussed. Laboratory protocols describe methodology to characterize mtDNA heteroplasmy by parallel sequencing. Each eukaryotic cell contains hundreds of mitochondria with hundreds of mitochondria genomes. Mutant and wild-type mtDNA may co-exist as heteroplasmy, and cause human disease. The purpose of this protocol is to simultaneously determine mtDNA sequence and quantify the heteroplasmic level. Another protocol describes procedures for obtaining tissue sections and cell material suitable for histological evaluation of OXPHOS activity and integrity and immunodetection of the complexes in tissue from patients suspected of mitochondrial disease. Emphasis lies on the diagnostic potential of these techniques to differentiate mtDNA from nuclear mutations. This e-book — a curated collection from eLS, WIREs, and Current Protocols — offers a fantastic introduction to the field of mitochondrial diseases for students or interdisciplinary collaborators.

Mitochondrial cytopathies are mutations in the inherited maternal mitochondrial genome, or the nuclear DNA-mutation. Mitochondrial respiratory chain disorders (RCD) are a group of genetically and clinically heterogeneous diseases, due to the fact that protein components of the respiratory chain are encoded by both mitochondrial and nuclear genomes and are essential in all cells. In addition, the biogenesis, structure and function of mitochondria, including DNA replication, transcription, and translation, all require nuclear encoded genes. Since mitochondria are present in every cell, every tissue, mitochondrial disorder usually affects multiple organs.

The Human Mitochondrial Genome: From Basic Biology to Disease offers a comprehensive, up-to-date examination of human mitochondrial genomics, connecting basic research to translational medicine across a range of disease types. Here, international experts discuss the essential biology of human mitochondrial DNA (mtDNA), including its maintenance, repair, segregation, and heredity. Furthermore, mtDNA evolution and exploitation, mutations, methods, and models for functional studies of mtDNA are dealt with. Disease discussion is accompanied by approaches for treatment strategies, with disease areas discussed including cancer, neurodegenerative, age-related, mtDNA depletion, deletion, and point mutation diseases. Nucleosides supplementation, mitoTALENs, and mitoZNF nucleases are among the therapeutic approaches examined in-depth. With increasing funding for mtDNA studies, many clinicians and clinician scientists are turning their attention to mtDNA disease association. This book provides the tools and background knowledge required to perform new, impactful research in this exciting space, from distinguishing a haplogroup-defining variant or disease-related mutation to exploring emerging therapeutic pathways. Fully examines recent advances and technological innovations in the field, enabling new mtDNA studies, variant and mutation identification, pathogenic assessment, and therapies Disease discussion accompanied by diagnostic and therapeutic strategies currently implemented clinically Outlines and discusses essential research protocols and perspectives for young scientists to pick up Features an international team of authoritative contributors from basic biologists to clinician-scientists

Mitochondrial dysfunction is increasingly being recognized as the basis of a wide variety of human diseases. Providing an authoritative update on our current knowledge of mitochondrial medicine, this text draws together world authorities from various fields to present general therapeutic strategies, as well as the treatments presently available in different specialties - thus making it essential reading for clinicians involved with the management of patients with mitochondrial diseases. A unique work, this text covers a range of specialties, including cardiology, ophthalmology, otology, nephrology, gastroenterology, hematology-oncology, and reproductive medicine, and does not focus exclusively on the more commonly known neurologic conditions. An accessible, user-friendly text, it also presents translational concepts of mitochondrial biogenesis and genetics in vignettes related to specific questions raised by the disease under discussion, rather than concentrating on basic science, which can often intimidate clinicians. This pioneering work is primarily directed to a clinical audience who are interested in the diverse and diagnostically challenging clinical presentations of mitochondrial diseases and their pathophysiology.
