Does Chromosome 4 Hold the Secret to Human Longevity? http://www.hhmi.org/news/kunkel.html After comparing the DNA of siblings who are extremely long-lived, HHMI researchers believe they have found a region on chromosome 4 that may hold an important clue to understanding human longevity. According to the researchers, their finding is "highly suggestive" that somewhere in the hundreds of genes in that region of chromosome 4 is a gene or genes whose subtle modifications can give a person a better chance of living well beyond the average life expectancy. The researchers believe that additional genetic analyses of nonagenarians and centenarians will lead to the identification of a few genes that confer longevity in humans. They also believe that their studies may turn up "good" versions of a multitude of genes that enable people to avoid age-associated diseases such as heart disease, stroke, diabetes, cancer and Alzheimer's disease. Research published in the August 28, 2001, issue of Proceedings of the National Academy of Sciences.
