A tiny fraction of people are naturally resistant to HIV infections, and scientists want to understand why.
Researchers have more recently begun studying African populations. In 2021 genetic variants were uncovered in Botswana that appear to either make peopleIn this new study of African people living with HIV-1 – the most common type of the virus – researchers found the opposite: a collection of 16 genetic variants that seems to limit HIV replication.
"By studying a large sample of people of African ancestry, we've been able to identify a new genetic variant that only exists in this population and which is linked to lower HIV viral loads," Although researchers don't yet know how CHD1L controls viral load, they're keen to find out because it could lead to new treatment options.
