A genetic marker that may protect some people against HIV infection has been found, a new study from researchers in France suggests.
This genetic marker occurs less frequently in people infected with HIV than in people who do not have the virus, the study showed.
If confirmed, it would be the second genetic marker ever found to give people some resistance to the infection that causes AIDS. The only such marker known to date is a particular mutation in a gene called CCR5. This gene, which is found in about 1 percent to 2 percent of people of European decent, provides near-complete protection against HIV infection, the researchers say.
