Scientists Discover Genetic Variant Limiting HIV Spread

Scientists have discovered a genetic variant that limits the spread of HIV. An international group of researchers has identified a new genetic variant in individuals of African descent that appears to restrict HIV replication after infection. The discovery was made through a combined analysis of nearly 3900 people. It could aid in the development of new antiviral drugs, similar to previous studies. However, scientists note that genetic resistance to HIV is likely associated with a complex interaction between two or more genetic variants, rather than a single exclusive characteristic.
