BBC NEWS | Health | Gene determines risk of HIV/Aids: "Scientists suggest people with more copies of a certain gene are less likely to become infected with the HIV virus or to develop Aids.
The US National Institutes of Health team say their finding could lead to a screening test to determine someone's susceptibility to HIV/Aids.
The gene the researchers studied is one which helps the body to fight the HIV virus.
The research was published online by the journal Science.
The gene encodes CCL3L1, a protein which blocks HIV which also interacts with CCR5 - a receptor protein that HIV uses as a doorway to enter and infect immune system blood cells."
Very cool shit... too bad it means more dumbasses will still try to reproduce!
