A gene has been identified that could predict the susceptibility of an individual to contracting HIV or developing AIDS, a report in the Journal of AIDS reveals. Scientists at the National Institute of Allergy and Infectious Diseases discovered the gene, called RANTES. Variations in the gene means it works in two ways: while it could double a person's susceptibility to contracting HIV, it also delays the length of time for progression to AIDS in HIV infected people by about 40%.
