A small mutation, a big impact: New findings on rare heart conditions

Cardiomyopathies are a group of mostly hereditary, rare heart diseases in which the structure of heart muscle tissue is impaired. This limits the heart's pumping capacity, leading to shortness of breath, reduced exercise ...

How brain cells restore healthy growth and connections after a disease-causing genetic deletion

Scientists at Virginia Tech's Fralin Biomedical Research Institute at VTC have discovered how an experimental therapy can help brain cells overcome the effects of a disease-causing genetic deletion. Instead of repairing the ...

Our genes may shape what we eat and our metabolic health

Ever wonder why some people crave sweets while others can take them or leave them? Preliminary findings from a new study suggest that people who carry certain genetic variants associated with a preference for sweet or fatty ...

Misfolded DNA blueprint: A new origin for genetic disease

Congenital heart disease is the most common birth defect, affecting approximately 1 in 100 babies born each year. One of the many causes of this disorder is having only one functional copy of the gene TBX5, rather than the ...

Rare aging disorder links 'biological clock' to disease

Scientists have discovered a rare genetic condition that causes people to age at a much faster rate, offering fresh insights into the aging process. The study shows for the first time how a "biological clock" present in every ...

Gene discovery could help prevent stroke in young people

UVA Health stroke researchers have identified a distinct and temporary pattern of gene behavior during cervical artery dissections, a leading cause of stroke in young people. These unusual gene changes may help explain the ...

Reproduction affects health—and so does biological sex

Starting one's sex life and having children at a young age can run in the family. But can pregnancy have beneficial health effects, and do the partner's genes contribute to them? "We are just beginning to understand how pregnancy ...

What a 'silenced' chromosome can tell us about autoimmunity

Systemic lupus erythematosus (SLE), the most common form of lupus, is an autoimmune disorder that occurs more frequently in women. Having multiple X chromosomes has been associated with an increased risk of developing lupus; ...

Why pollution affects some asthma patients more than others

For many people with asthma, air-quality advisories are harbingers of worsening symptoms. But for reasons science has struggled to explain, the extent to which pollution exacerbates asthma varies widely from person to person.

Ménière's disease may begin early in inner ear development

By analyzing genetic data from nearly 2 million people, researchers have unlocked a new scientific understanding of Ménière's disease, a chronic and often debilitating inner ear disorder. A team from the Perelman School of ...

AI and polygenic scores improve breast cancer risk assessment

A risk model that combines a mammographic artificial intelligence (AI) risk score with polygenic and clinical risk scores more accurately identifies women at high risk of developing breast cancer than clinical risk scores ...
