An analysis of genetic data from over 900,000 people shows that certain stretches of DNA, made up of short sequences repeated ...

A large genetic study shows that many people carry DNA sequences that slowly expand as they get older. Common genetic ...

There is a genetic feature known as a repeat expansion, in which short sequences are repeated continuously. Some of them ...

Scientists discovered that aging DNA repeats expand at wildly different speeds—and in some people, the consequences can be devastating. A sweeping genetic study drawing on data from more than 900,000 ...

But some Neanderthal DNA helped modern humans survive and reproduce, and thus it has lingered in our genomes. Nowadays, ...

The tiny little powerhouses of our cells, the mitochondria, are unique among organelles because they carry their own tiny ...

In a recent study published in the journal Nature, an international team of researchers developed a novel approach to infer parent-of-origin (PofO) of alleles without parental genomes. Genome-wide ...

The AHA recommended whole exome or whole genome sequencing as first-line diagnostic tools for mitochondrial diseases.
