Caltech Researchers Find Longevity-Linked Mutation

CBNobi writes "A study headed by researchers at CalTech have found a genetic mutation occuring in mitochondrial DNA that may signify longevity. The researchers found that the particular mutation occurred in 17% of centenarians, but only 3.7% of younger individuals. They also found the mutations in identical twins, which is a possible sign of inheritance. Researchers believe the mutation controls factors in DNA replication. The report information is available in a press release by CalTech, and the research abstract is also available."
