Its known why and is not a possible reason but fact. Its a naturally occurring genetic mutation. HIV seeks out and uses CD4 the protein that covers the T helper cell that HIV infects. The mutation creates a different protein on the T helper cell that HIV is not able to detect. Without binding to T helper cells HIV will wither and die. 4% of Scananavians,3% of western Europeans and sadly 0% of sub-sahran Africans have the mutation.
