Immunity To AIDS?

Many people don't know that it is possible to be naturally immune to HIV, the virus that cause AIDS. This is thanks to a genetic mutation in ones DNA called Delta 32 (CCR5-delta 32). This mutation cuts off the means for a virus, to attach to our white blood cellsand enter the immune system. It must come from both parents to cause immunity,but if in possession of only one chromosome for delta-32 it is likely to delaythe virus from spreading for long periods of time. This mutation always have a positive effect on any individual and never negative.
