  • Mitochondria play a key role in cell homeostasis as a major source of intracellular energy (adenosine triphosphate), and as metabolic hubs regulating many canonical cell processes. Mitochondrial dysfunction has been widely documented in many common diseases, and genetic studies point towards a causal role in the pathogenesis of specific late-onset disorder. Together this makes targeting mitochondrial genes an attractive strategy for precision medicine. However, the genetics of mitochondrial biogenesis is complex, with over 1,100 candidate genes found in two different genomes: the nuclear DNA and mitochondrial DNA (mtDNA). Here, we review the current evidence associating mitochondrial genetic variants with distinct clinical phenotypes, with some having clear therapeutic implications. The strongest evidence has emerged through the investigation of rare inherited mitochondrial disorders, but genome-wide association studies also implicate mtDNA variants in the risk of developing common diseases, opening to door for the incorporation of mitochondrial genetic variant analysis in population disease risk stratification.

  • Mitochondrial disorders are a highly diverse group of conditions that can affect almost every major system in the human body, often mimicking common disorders. This clinical variety often results in prolonged and often dangerous, diagnostic delays. This textbook provides a practical framework, to enable rapid identification, investigation, and treatment of mitochondrial disorders across the spectrum of clinical practice. Clinically relevant and comprehensive, this textbook employs a system- and case-based approach for practitioners of all levels. It focuses on major phenotypic features, syndromes and management relevant for clinical practice, within a broad overview of the field. This interactive book supports readers with knowledge distilled from over 20 internationally recognized, mitochondrial experts.
