In what the researchers describe as the primary examine of its form, they analyzed and deciphered your complete genetic codes of a person and a lady who lived previous the age of 114. The 2 so-called supercentenarians had:
- DNA that seemed to be similar to individuals who didn't have lengthy lives
- about the identical variety of gene variants linked to elevated illness danger as seen in folks from the overall inhabitants whose genomes have been sequenced
- greater than 50 potential longevity-associated variants in genes, a few of which had been surprising and had not been seen earlier than.
