Toxic exposure creates disease risk over 20 generations, epigenetic inheritance study suggests
A single exposure to a toxic fungicide during pregnancy can increase the risk of disease for 20 subsequent generations—with inherited health problems worsening many generations after exposure. Those are the findings of a new Washington State University…

Gene variants help explain why food allergies run in families
People often remark that allergies run in their family, but the genetic causes have remained unclear. Previous food allergy genetic research has relied upon broad but surface-level methods called genome-wide association studies.

New method estimates Epstein-Barr virus in blood using standard genome sequencing data
The Epstein-Barr virus (EBV) can cause certain types of cancer or autoimmune diseases, but how the body controls this common viral infection is largely unknown. Researchers at the University Hospital Bonn (UKB) and the University of Bonn have now ident…

Household cat could hold the key to understanding breast cancer
The first study of multiple cancer types in cats has identified genetic changes that could help treat the condition in humans and animals. By analyzing different types of tumors from almost 500 pet cats across five countries, experts at the Wellcome Sa…

DeepRare AI outperforms doctors on rare disease diagnosis in head-to-head test
Rare diseases are complex medical disorders that are notoriously difficult to diagnose because many present with a wide variety of symptoms that can overlap with more common illnesses. Currently, around 300 million people globally are affected by these…

Urine DNA test may spot Lynch syndrome urinary cancers before symptoms
A pioneering genetic test is improving early diagnosis and treatment for people with hereditary cancer caused by a genetic condition. The test, developed with the help of Newcastle University scientists, identifies specific signs in a person’s DNA that…

Huntington’s disease offers a rare clean test case for brain research
Neuroscience rarely enjoys clean experiments. Most brain disorders are mosaics of risk genes, aging, lifestyle and chance that leave their origins obscured. Huntington’s disease (HD) is different. It begins with a single genetic expansion—a repeated st…
