...edicine. Drug resistance is one of the most common reasons why therapy for HIV, the virus that causes AIDS, fails. The test, which detects genetic changes, or mutations, in HIV, also may help scientists understand how the constantly evolving virus develops drug resistance, Gao said.

"This genetic marker may influence some of the variables that lead to drug use, but there are many other variables that are not related to this gene. This is part of the reason that there are inconsistencies in the ...Longevity gene also protects memory, cognitive function
.... "But little effort has been made to identify the reasons for longevity in exceptionally old people, and why they don't develop disease. In studying these centenarians, we hope to learn what factors lessen their risk for diseases that affect the general population at a much younger age.
