LONDON , March 31 (Xinhua) -- Researchers have identified gene changes that can cut a person's lifespan by up to three years, according to a study published online Thursday in the journal Nature Communications.
A team led by researchers from the University of Edinburgh made the discovery by analyzing genetic information from more than 152,000 people who participated in the UK Biobank study - a long-term record of the health of thousands of volunteers.
They have discovered two separate areas of the human genome where differences in the DNA code may affect how long a person lives.
The two changes - known as variants - are relatively common in the population.
More than two thirds of us will inherit a single copy of one of them from either our mother or father, according to the study.
