Mutations are changes in the molecular 'letters' that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

A new single-cell profiling technique has mapped pre-malignant gene mutations and their effects in solid tissues for the ...

A new study headed by teams at the Wellcome Sanger Institute, EMBL’s European Bioinformatics Institute (EMBL-EBI), and Open Targets has indicated how mutations that cause cancer drug resistance fall ...

Researchers have refined a powerful DNA sequencing tool that can uncover hidden mutations that occur naturally in our bodies as we age. In the largest study to date, they have used the tool to provide ...

Despite progress in defining functional elements of noncoding DNA, it is still not fully understood. UCLA researchers, using an experiment that elucidated the function of tens of thousands of ...

From the time we are conceived and through old age, genetic mutations accumulate in all our tissues, eluding the body’s typically efficient DNA repair machinery and potentially affecting our health ...

A Ludwig Cancer Research study has punctured a longstanding assumption about the source of the most common type of DNA mutation seen in the genome—one that contributes to many genetic diseases, ...

New research published in Nature Communications into hidden mutations in mitochondrial DNA has uncovered how high mutational levels coincide with later life and link to aging markers. Mitochondria are ...

A research group led by the University of Osaka has discovered that the DNA repair enzyme Polβ plays a crucial role in protecting the developing brain from harmful mutations. The study found that a ...
