Abstract:
Human immunodeficiency virus type 1 (HIV-1) infection is generally characterized by a long-term, chronic disease course that gradually progresses to acquired immunodeficiency syndrome (AIDS). However, a small fraction of HIV-1-infected individuals remain both clinically and immunologically healthy for 10 years or more after seroconversion. Conversely, the disease of another significant fraction is characterized by an extremely rapid progression to AIDS within 1 year. There are also individuals not infected with HIV-1 who have had repetitive sexual exposure to HIV-1 in extremely high-risk situations. Determining the host factors involved in these different susceptibility and disease courses would be helpful for better understanding AIDS and its control. Today, a worldwide scientific endeavor called the Human Genome Project has completed the production of a full-length sequence of the 3 billion base pairs that make up the human genome. The Human Genome Project has also revealed the presence of variation in human genomes. Relating these genetic differences to human phenotypes offers a very attractive prospect for a genetic understanding of the different sensitivities to various human diseases, including cancer, brain and heart diseases, allergy, and infectious diseases. In this review, we present examples of human genetic variation that can affect HIV-1 infection and disease progression.
