Scientists have uncovered a breakthrough in the fight against a rare genetic condition that causes children to age much faster than normal. The discovery involves “longevity genes” found in people who live exceptionally long lives, often beyond 100 years. Researchers from the University of Bristol and IRCCS MultiMedica found that these genes, which help maintain the health of the heart and blood vessels during aging, could reverse some of the damage caused by this devastating disease.

The study, published in Signal Transduction and Targeted Therapy, is the first to show that a gene from long-lived individuals can slow down heart aging in a model of Progeria. Known scientifically as Hutchinson-Gilford Progeria Syndrome (HGPS), this rare and fatal disorder causes children to exhibit signs of “accelerated aging.”

Progeria stems from a mutation in the LMNA gene, which leads to the creation of a harmful protein called progerin. This protein disrupts normal cell function, particularly in the heart and blood vessels. Most affected children die in their teenage years from heart complications, though some, like Sammy Basso — the oldest known person with Progeria — live longer. Sammy passed away on October 24, 2024, at the age of 28.
