Abstract To test the hypothesis that centenarians are free from deleterious mitochondrial variations, we analyzed amino acid variations in the cytochrome b molecule of 64 Japanese centenarians. Although the frequencies of some variations, such as N260D and G251S, differed significantly between centenarians and patients with Parkinson's disease, the most striking feature of centenarian cytochrome b was the rareness of amino acid variations in contrast to the variety of amino acid replacements in patients with Parkinson's disease. These results suggest that centenarians are genetically hitting the “golden mean” (less variation from the consensus cytochrome b sequence or less mismatch with other subunits). A multiplex detection system for various deleterious variations in combination with genetic tests for longevity‐associated genotypes will be necessary to predict longevity or age‐related diseases. © 2002 Wiley‐Liss, Inc.
