A GENETIC mutation common in African Americans slows the progression of HIV, yet paradoxically increases the risk of contracting the virus in the first place. A clue that race-specific genes are involved in HIV came in 2002, when Sunil Ahuja of the University of Texas Health Science Center in San Antonio and colleagues discovered a mutation in the CCL5 gene that accelerates the progression of HIV-1, the most common form of the virus. Though the mutation was found in people of all races,
