Geisinger research identifies genetic risk factor for stroke

DANVILLE, Pa. – A team of Geisinger researchers has identified a common genetic variant as a risk factor for stroke, especially in patients older than 65. Cerebral small vessel disease (SVD) causes about a quarter of ischemic strokes worldwide and is the most common cause of vascular dementia. SVD can manifest as lesions on […]

Genetic rewiring behind spectacular evolutionary explosion in East Africa

How do viruses protect their genetic information?

Researchers uncover the mystery of how viruses avoid encapsulating unwanted genetic material from the crowded cell cytoplasm. Image credit: Juan Gaertner/Science Photo Library Understanding the intricate mechanisms behind viral infections is crucial to fighting them — as evidenced by the current global pandemic caused by the SARS-CoV-2 virus. Intensive research efforts have gone into understanding […]

New statistical method exponentially increases ability to discover genetic insights — ScienceDaily

Pleiotropy analysis, which provides insight on how individual genes result in multiple characteristics, has become increasingly valuable as medicine continues to lean into mining genetics to inform disease treatments. Privacy stipulations, though, make it difficult to perform comprehensive pleiotropy analysis because individual patient data often can’t be easily and regularly shared between sites. However, a […]

Common brain malformation traced to its genetic roots

IMAGE: The lowest part of a child’s brain is visible below the bottom of the skull in this MRI scan and shows evidence of a Chiari 1 malformation. Researchers at Washington… view more  Credit: David Limbrick About one in 100 children has a common brain disorder called Chiari 1 malformation, but most of the time such […]

Clinical criteria for diagnosing autism inadequate for people with genetic conditions

People with certain genetic conditions are likely to have significant symptoms of autism, even if they do not meet all diagnostic criteria, a study concludes. Researchers at Cardiff University say their findings show clinical services need to adapt so that people diagnosed with autism-linked genetic conditions are not denied access to vital support and interventions. […]

Light flips genetic switch in bacteria inside transparent worms

New mammal reference genome helps ID genetic variants for human health

The rhesus macaque is the most widely studied nonhuman primate in biomedical research. A genome sequencing project for this species, led by researchers at Baylor College of Medicine, the University of Missouri and the University of Washington, has created a new framework for study of this important primate. Research published in the journal Science has […]
