A new study finds some people are less likely to become infected with HIV and less likely to develop AIDS.
Apparently, it depends on whether they are born with some extra copies of a specific gene. This study comes from the University of Texas where researchers analyzed the genes of 4,300 people, half of whom were HIV positive. They found that those with multiple copies of the gene called CCl3l1 were less likely to be infected with HIV, but those with fewer copies were more likely to have HIV and more likely to develop a rapid progression to aids.
Researchers are hopeful that testing for levels of this gene could someday predict who is most vulnerable to aids and tailor therapy to those patients.
