Scientists Claim they can Estimate Life Expectancy from DNA

A group of scientists from the University of Edinburgh claim to be able to estimate whether a person has a life expectancy of 5 years more than another by looking at their DNA.

After studying the DNA of more than half a million people, scientists at the University of Edinburgh say they can analyze the DNA of two people of any age and predict if one will live longer than another.

More than estimating the exact number of years they will live, from a DNA analysis they give a note of life expectancy.

For example, if you select a group of 100 individuals and divide them into groups according to their life expectancy score, the group with a higher score would have a life expectancy of 5 years more than those with less grade.

By analyzing the genes of more than 500,000 donors and comparing them to the age at which they died, they were able to identify 12 parts of the human genome that seem to influence life expectancy. Some were already known to be associated with Alzheimer’s or heart disease, but 5 of them were identified for the first time.

What is the goal of predicting life expectancy with DNA?

What the scientists wanted with the study was to identify the genes that accelerate aging, but they failed to detect them. However, the 5 new parts associated with life expectancy could serve as a starting point for new research.

Thus, researchers also believe that in the future you can submit to a test and know if you are more likely to have a longer life than the average or not. However, it is worth wondering what is the utility of having this information if we can not alter it yet.
