Mitochondrial DNA heteroplasmy is independently associated with an increased risk of CLL, suggesting potential as a novel biomarker for early risk identification.

The human genome is contained in the nucleus of almost every cell in the body. But those cells also contain multitudes of mitochondria, and these incredible little power-generating organelles carry ...

Mitochondria are well known as the powerhouses of the cell because of their energy generating capabilities. These little organelles are very special, because they also carry their own tiny little ...

In a step toward treating mitochondrial diseases, researchers in the Netherlands have successfully edited harmful mutations in mitochondrial DNA using a genetic tool known as a base editor. The ...

Tsukuba, Japan—The human genome is broadly classified into the genome residing in the cell nucleus (nuclear DNA) and the genome residing in the mitochondria (mitochondrial DNA: mtDNA). Mitochondria ...

It often starts with something small—a dark spot on the skin that looks a little off. A dermatologist takes a closer look, runs a biopsy, and soon after, the diagnosis arrives: melanoma. If the cancer ...

For decades, the dream of fixing harmful mutations in mitochondrial DNA felt out of reach. Scientists have long known these mutations cause serious diseases that pass down only through mothers. They ...

Cancer Research UK-funded scientists have made an unusual discovery that could help to identify patients who are up to two and a half times more likely to respond to currently available cancer drugs.

The identification of alleles associated with complex hearing defects, such as presbyacusis (age-related hearing loss, AHL), presents a formidable challenge to geneticists. In the February Nature ...

Mutations in the mitochondrial genome have been associated with several genetic diseases. In an Advanced Online Publication of Nature Genetics, Robert McFarland and colleagues from the University of ...
