Whether you turn red when drinking alcohol, dislike certain smells, or metabolize drugs differently from others, the explanation often lies in your DNA, or more precisely, your gene types.

Many of the ancient southern Africans, including those who lived between about 10,200 and 1,400 years ago, "fall outside the range of genetic variation among modern-day individuals," the researchers wrote in the study, "and form an extreme end of human genetic variation."

In a breakthrough study, scientists have discovered that a variant in one gene, GRIN2A, can directly cause mental illness – something previously believed to be the result of several mutations working together.

After more than 50 years of research, scientists still don't know exactly what causes autism. But the data make clear that genetics are an essential piece of the puzzle.

Sequencing diverse populations revealed over 41,000 transcripts missing in Eurocentric references, exposing ancestry bias that limits insights into global disease risk.

A new study has developed a powerful computational method that can detect how genes interact with each other to influence complex traits in humans at a scale previously impossible. The new method was applied to massive datasets that pair individual genomes and traits to find evidence for such interactions.

Human gene maps contain major blind spots because they were built largely from the DNA sequences of people with European ancestry, according to a study published today in Nature Communications.

Doctors have now used a gene-edited pig liver to keep a human alive, not as a thought experiment in a lab but as a real bridge for a failing organ. The procedure signals a turning point in transplant medicine,
