Role of Mitochondrial Genetics in Complex Diseases
The study of genetic disease is often centered on the human nuclear genome consisting of ~3.1 billion nucleotides and 25,000–30,000 genes located on the 23 pairs of chromosomes, whereas the mitochondrial genome has received less attention. Each cell contains numerous mitochondria and each mitochondrion contains several copies of mitochondrial DNA (mtDNA). Thus, a cell contains several thousand ...
متن کاملMitochondrial genetics: a paradigm for aging and degenerative diseases?
Studies of diseases caused by mitochondrial DNA mutations suggest that a variety of degenerative processes may be associated with defects in oxidative phosphorylation (OXPHOS). Application of this hypothesis has provided new insights into such diverse clinical problems as ischemic heart disease, late-onset diabetes, Parkinson's disease, Alzheimer's disease, and aging.
متن کاملMitochondrial genetics
INTRODUCTION In the last 10 years the field of mitochondrial genetics has widened, shifting the focus from rare sporadic, metabolic disease to the effects of mitochondrial DNA (mtDNA) variation in a growing spectrum of human disease. The aim of this review is to guide the reader through some key concepts regarding mitochondria before introducing both classic and emerging mitochondrial disorders...
متن کاملMitochondrial genetics
The mitochondrial genome is vital for Caenorhabditis elegans metabolism, physiology, and development. The C. elegans mitochondrial DNA is typical of animal mitochondrial genomes in its size and gene content. It is 13,794 nucleotides in length and encodes 36 genes: 2 ribosomal RNAs, 22 transfer RNAs, and 12 protein subunits of the mitochondrial respiratory chain. Although it represents only a sm...
