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 ...

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 ...

Researchers have detected a human genetic variant that influences the sex ratio of children. Additionally, they found that many hidden genetic variants of sex ratio may exist in human populations.

Researchers have developed a new framework to study the functional impact of genetic background on the expression and severity of neurodevelopmental features associated with a deletion of a portion of ...

Individuals that share the same deletion of a portion of chromosome 16 are at risk of developing neurodevelopmental disorders, but some experience severe intellectual disability or developmental delay ...

The root causes of most forms of Alzheimer's disease largely remain a mystery. Now, researchers have revealed a new piece of the puzzle. Neurogeneticists at the University of Florida led by Lien ...

Researchers identified a new genetic mutation that may allow some people to survive, even thrive, on three hours of sleep. The mutation is called SIK3-N783Y. Scientists said mice test subjects ...

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 ...

Earth's biodiversity is in crisis. An imminent "sixth mass extinction" threatens beloved and important wildlife. It also threatens to reduce the amount of genetic diversity—or variation—within species ...
