Genes Reveal Your Biological Age
A team of reasearchers say they're able to determine a person's "biological age," through a signature based on 150 genes, and that it may be a better indicator than chronological age of how long a person may live, according to a new study published in the journal Genome Biology.
The scientists analyzed genetic material from healthy people who were 65 years old, looking for genes that indicated whether people staying healthy as they aged. They found 150 genes to analyze and calculate a person’s “healthy age gene score.”
To evaluate these scores in tracking overall health, the researchers tested the method in a group of 70 year olds, finding that the good scores were an indicator of better health, including cognitive ability.
They found that people diagnosed with Alzhemier’s had lower healthy age gene scores, suggesting dementia could be a type of accelerated aging. However, it was unclear whether a healthy gene score could be used to predict the likelihood of Alzheimer’s disease.
