Predicting Life Expectancy – with DNA

Genetics play a role in estimating an individual’s longevity. By analyzing their DNA, it is possible to make predictions about how long a person may live.

A recent study has revealed that DNA can be used to predict life expectancy. Led by Doctor Peter Joshi and his team, the study produced a scoring system that evaluates the effect of genes on an individual’s life expectancy. This scoring system is based on genetic mutations that are associated with a higher risk of premature death. By analyzing these genetic markers, scientists are able to accurately predict how long someone will live. The implications of this research could have far-reaching effects in terms of healthcare and public policy.

Research conducted on over 500,000 individuals found that those belonging to the top 10th percentile of the population could expect to live up to five years longer compared to those who were in the bottom tenth.

Researchers have discovered twelve sections of the genome that impact life expectancy. Of these, five were not previously reported and had a major effect on one’s lifespan. These same areas were connected to deadly conditions such as cardiovascular disease, highlighting the importance of their findings.

The primary focus of this study was to identify genes that impact the rate of aging in humans. Unfortunately, the effects were too insignificant for detection in this research. This implies that if such genes exist, they are yet to be found.
