THURSDAY, Nov. 6, 2014 (HealthDay News) -- Even among people who live well into their 90s, those with a particular gene variant may survive the longest, a new study finds.
The variant is in a gene known as CETP, and researchers have known for more than a decade that people who carry it have a better shot at an exceptionally long life -- past 95 or even 100.
CETP is involved in cholesterol metabolism, and the longevity-linked variant raises blood levels of HDL cholesterol (the "good" kind) and promotes larger-than-normal HDL particles, researchers say.
The new findings show that even when you look at people who've already lived beyond age 95, those with the "favorable" CETP variant survive longer, said Dr. Sofiya Milman, an assistant professor at the Albert Einstein College of Medicine in New York City.
Milman was scheduled to present the findings Thursday at the annual meeting of the Gerontological Society of America in Washington, D.C. Data and conclusions presented at meetings are usually considered preliminary until published in a peer-reviewed medical journal.
The results build on work that began at Einstein in the late 1990s. Researchers there have been studying centenarians in and around New York City, all of Ashkenazi Jewish descent. They've found that people in this long-lived group often carry the CETP variant, and have very high HDL levels.
