The association design is a potential limitation of our study, and a longitudinal study might provide more robust data. Unfortunately, no longitudinal studies in humans have been performed to obtain more robust conclusions, espe- cially in long-lived subjects ((cid:7) 85 yr of age), in which a long follow-up period would be extremely difficult to achieve. Furthermore, it should be pointed out that the rationale for assessing the potential role of the IGF-I signaling pathway on longevity derives from a large number of studies performed in laboratory models of longevity and in which a cause-effect mechanism has already been proven.

In conclusion, our study shows that genetic variability at
