Variation in DARC Gene Causes More Suscesptibilty to HIV in Peoples of African Descent


“People with the Duffy protein carry on their red cells and in their circulatory system a larger amount of immune molecules known as chemokines, which confers protection against HIV. In addition, the Duffy protein can act as a sponge and soak up infectious HIV particles, providing additional protection against the virus. People who have a variation of the gene – which includes a large proportion of people of African descent – don’t carry the Duffy protein, and are therefore at higher risk of getting infected when exposed to HIV.”
