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 mega-database of half a million mutations may flag new ways of treating genetic disease, scientists say. When you purchase through links on our site, we may earn an affiliate commission.

one shared by family members and present at birth. Yet what physicians are only now beginning to realize is that somatic mutations may help explain illnesses that were never considered “genetic ...

To achieve this, the donated cells must replicate again and again — and again. It’s a cycle that might put recipients at risk if a new, potentially harmful mutation arises or if a mutation present in ...

2 in family 1, Figure 1A ... This missense, Tyr351Asn, mutation was confirmed by amplification refractory mutation system polymerase chain reaction (ARMS-PCR; Figure 1). Familial isolated ...

"The analysis identified low frequency mutations in the hemagglutinin gene of a sample sequenced from the patient, which were not found in virus sequences from poultry samples collected on the ...

But there is no sign that mutations are widespread in nature. By Benjamin Mueller After someone in southwest Louisiana was hospitalized with a severe case of bird flu, the first such illness ...

The first severe case of bird flu in the U.S. is showing signs of mutation, stoking fears that the virus could become more transmissible among humans, the U.S. Centers for Disease Control and ...

The day after Christmas, the Centers for Disease Control and Prevention announced that it had identified new mutations to the H5N1 bird-flu virus in a “severely ill” patient in Louisiana.

Genetic sequences of H5N1 bird flu viruses collected from a person in Louisiana who became severely ill show signs of development of several mutations thought to affect the virus’ ability to ...
