I wouldn't bank on it though, Stronzo. The prevalence of the D 32 gene in Europeans is 1:7 tops. But to have the resistance to HIV you'd need to be homozygous, i.e. a matching pair, one from each parent. So both parents would need to be heterozygous, i.e. carry one, with the other gene being the normal, non-D 32 gene varient (allele).
Doing math: the chance of both parents carrying one allele is 1 in 7x7 = 1:49. That would only give you a 1:4 chance of ending up as homozygous. So if you don't know the D 32 status of your parents, the chance of you being homozygous is 4 x 49 = 196. Let's call it 0.5%. Pretty long odds.
However, being heterozygous is said to delay the onset of AIDS by an average of 2yrs if you get infected with HIV.
Ironically, the D 32 mutation is a damaged gene, which is meant to express a protein in the wall of certain white blood cells that helps fight infection, and the lack of it would reduce resistance to viruses. However, HIV actually binds to this protein and uses it to enter the white blood cell so that it cannot be attacked by antibodies. If this protein is missing HIV cannot enter the cell.
It does however raise the possiblitiy of gene therapy to turn people into homozygous D 32, and therefore resistant to HIV and then the pope can keep his condoms
