Common genetic marker associated with faster Parkinson’s disease progression
A new study by investigators from the Mass General Brigham Neuroscience Institute has identified common genetic variants in the MC1R gene as markers of faster motor decline in people with Parkinson’s disease (PD). The findings, published in JAMA Neurol…

Spleen scans reveal genetic clues to coronary artery disease risk
A new study led by investigators from Mass General Brigham reveals that certain features in the spleen hidden within imaging scans may signal a person’s risk of coronary artery disease (CAD), suggesting targets for prevention and treatment. The finding…

Blood protein analysis could help diagnose rare diseases missed by genome sequencing
Researchers from Queen Mary University of London, the Berlin Institute of Health at Charité (BIH) and Genomics England have shown that measuring proteins in the blood can provide important additional clues about the effects of genetic variants, helping…

Certain DNA signatures may reveal which prostate cancers are most likely to spread
Prostate cancer is the second most common form of cancer among men globally. Yet, we still know relatively little about why the disease develops or why some men live with it for years while it progresses aggressively in others.

Calorie restriction reveals a potential way to slow age-related DNA mutations
Mutations are changes in the molecular «letters» that make up DNA, the genetic blueprint for cells. Mutations build up with age in every cell when DNA is damaged or when cells make mistakes in fixing or copying it. Most mutations are harmless, but when…

Nearly half of depression risk factors overlap with physical illnesses, especially gut disease
QIMR Berghofer researchers have identified a strong genetic link between gut-related health conditions and depression in a study offering new insights into why physical illnesses often accompany the mental health condition.

New framework boosts the accuracy of disease risk prediction from genetic data
Investigators at Cedars-Sinai Health Sciences University have developed a computational framework to improve how genetic data is used to estimate an individual’s inherited risk of developing conditions like Alzheimer’s disease, type 2 diabetes, high bl…

How losing the ‘guardian of the genome’ can damage DNA and drive cancer
A new study finds that when p53, one of the most important cancer-protecting genes, stops working, cells produce too much RNA and consume excessive amounts of the building blocks needed to copy their DNA. This shortage disrupts DNA replication, leading…

Origins of COPD may lie in how some children’s lungs develop, but only when they are exposed to polluted air
Chronic obstructive pulmonary disease (COPD) is a serious, incurable lung disease that is common in older people. However, researchers are learning that the origins of the disease may lie decades earlier in how children’s lungs grow and develop.
