Each year, roughly the same numbers of boys and girls are born. But in individual families, some couples have four or more daughters and no sons, and some have all male children and no female children ...

In simple terms: a mutation is a stable change in genetic sequence that can be copied when cells or viruses replicate. Most mutations have no detectable effect, some contribute to disease, and a small ...

A massive genetic analysis reveals a rare mutation that drives lung cancer risk sharply higher in non-smokers, suggesting ...

Modern HIV medicine is based on a common genetic mutation. Now, researchers have traced where and when the mutation arose—and how it protected our ancestors from ancient diseases. What do a ...

Rerunning tumour evolution in mice shows how cancer develops after DNA damage and reveals that background genetics and acquired mutations interact to shape genome stability and selection. This ...

Research co-authored by an Oklahoma Museum of Natural History curator, her graduate student and an international team of scientists has shed new light on the evolutionary "toolkit" animals use to ...

Mutation rates govern the introduction of genetic variation and influence evolutionary trajectories, disease susceptibility and species diversity. Rates are shaped by a balance between DNA damage, ...

Neurogeneticists have discovered a novel genetic mutation and associated buildup of toxic proteins in the brain -- a type of buildup distinct from amyloid or tau, proteins that have long been the ...

A multi-ancestry polygenic risk score improved HCM risk prediction in a diverse U.S. population of more than 258,000 people.

The root causes of most forms of Alzheimer’s disease largely remain a mystery. Now, researchers have revealed a new piece of the puzzle. Unexpectedly, the investigators found that 45 of 80 autopsy ...
