Juan Ponce de LeÃ³n never found his Fountain of Youth, but researchers may have discovered a genetic equivalent hidden in the DNA of centenarians.
Only one in 6,000 people reaches the century mark and just one in 7 million lives to be a supercentenarian â€” someone who is 110 or older. But a new study, published online July 1 in Science, suggests that more people may have the right genetic stuff for extreme longevity.
In the new study, researchers looked at genetic markers called single nucleotide polymorphisms, or SNPs, in 1,055 centenarians and 1,267 younger people, all of European descent. The scientists found 150 genetic SNP variants linked to extreme longevity.
