Something interesting for those who have their 23andme.com genetic results: 1% of the population have genetic immunity (high resistance) to the most common strains of HIV: these HIV-immune individuals are those who carry two copies of the genetic mutation called CCR5 Delta32. To check if you have this genetic immunity to HIV, click ➤ HERE. This will take you to the appropriate webpage on 23andme.com, where you can see how many copies of this CCR5 Delta32 mutation you have. On that webpage, you will see this: Gene · · · Position· · · SNP · · · · Versions· · · Your Genotype CCR5 · · · 46414947· · · i3003626· · · · · · · · · ??? If your genotype is DD, then you have immunity / resistance to HIV. If your genotype is II or DI then you are not resistant to HIV infection. More specifically: • If your genotype is II then you have no copies of the CCR5 Delta32 mutation, and are not resistant to HIV infection. • If your genotype is DI then you have one copy of the CCR5 Delta32 mutation, are not resistant to HIV infection, but may have slower progression to AIDS after infection. Around 10% of Caucasians have one copy of CCR5 Delta32. • If your genotype is DD then you have two copies of the CCR5 Delta32 mutation, and are resistant to infection by the most common strain of HIV people usually encounter, though protection is not complete. Around 1% of Caucasians have two copies of CCR5 Delta32. Notes: The CCR5 Delta32 mutation has the RSID of rs333. However 23andme call this mutation i3003626.
