Circulating tumor DNA (ctDNA), small pieces of DNA released from dying tumor cells into the bloodstream, can be easily and non-invasively identified and examined through a simple blood test. This ...

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 ...

Only around two percent of the human genome codes for proteins, and while those proteins carry out many important functions of the cell, the rest of the genome cannot be ignored. However, for decades ...

(Top) Point mutations (red star) in the DNA give rise to mutant mRNA and polypeptides that either misfold and are degraded—resulting in loss‐of‐function—or evade quality control to form toxic ...

A new 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, including cancer. A ...

Researchers have discovered how orange cats got their coats — and why so many of them are male. The coat color comes from a genetic mutation on the X chromosome of orange, calico and tortoiseshell ...

Experiments on an ultra-rare genetic mutation that causes neurodegeneration in children have helped uncover a new mechanism ...

From Tama, Japan's most famous stationmaster calico cat, to the lasagna-loving, ginger Garfield, cats with orange fur are both cultural icons and beloved pets. But their distinctive color comes with a ...

Researchers are adding new evidence to the emerging concept that 'silent' or synonymous mutations may have crucial consequences. Their study showed how a synonymous mutation in one gene can ...
