In Mendelian inheritance patterns, you receive one version of a gene, called an allele, from each parent. These alleles can be dominant or recessive. Non-Mendelian genetics don’t completely follow ...

Genetic testing can help doctors diagnose some neurological disorders, such as Huntington’s disease. It can also provide insights into a person’s risk of future health conditions. Genetic testing ...

"Monogenic" diseases, triggered by mutations in just one gene, may actually be more complex than scientists thought.

— The genetic roots of a disease or disorder do not always grow into clear cut, easily diagnosed clinical features. Even if a parent and child have the same genetic marker implicated in an outcome, ...

Rare genetic traits are features that are uncommon within the general population. They can lead to different observable features or to rare physical abilities. Rare genetic traits are typically ...

Rapidly testing hundreds of thousands of DNA sequences, scientists identified specific genetic variations contributing to blood pressure, cholesterol, and blood sugar.

Researchers have uncovered shared genetic pathways that link multiple psychiatric disorders. These new findings have the potential to change the way psychiatric disorders are diagnosed and treated, ...

"It's a slow-moving train wreck," Mike Graglia says about his 12-year-old son Tony's rare genetic disease with no cure. Caused by a tiny fluke of nature—a mutation in a gene known as a SYNGAP1—the non ...

Scientists have identified how specific genetic changes function in cells to influence disease risk and other human health ...

“Ultimately, we'll help the people we discriminate against if we try to understand more about them; genetics will lead to a world where there is a sympathy for the underdog.”—James D. Watson A recent ...
