Sixteen gene variations
linked to life expectancy, of
which 14 are newly
discovered, have been
recently identified by
specialists. They also
revealed three genes whose
low expression in the brain is
linked with longevity.
In the United States, life expectancy is
currently averaged at 78.8 years,
according to data from the Centers for
Disease Control and Prevention (CDC).
They also identify the leading causes of
death, naming heart disease, cancer , and
chronic respiratory diseases as some of
the main culprits.
Scientists have previously looked at our
genetic makeup for clues that indicate
how long each person is likely to live.
However, until now, only two genes had
been identified as linked with longevity
(defined as living beyond age 85) in
humans.
A new study led by Prof. Zoltán Kutalik -
from the Institute of Social and
Preventive Medicine and the Swiss
Institute of Bioinformatics, both in
Lausanne, Switzerland - has now
identified a total of 16 genetic markers
that dictate how long a person will live.
Of these, 14 are completely new
discoveries.
