Is HIV progression sex-linked?

German researchers have identified a single-nucleotide polymorphism (SNP) on the X chromosome that appears to be connected to a slower development of AIDS after HIV infection in women with the characteristic compared to men (with or without the SNP) or women who lack it. The study was done with data from American women of European descent; when scientists searched for the prevalence of the SNP in other ethnicities, they found that Asian women of Japanese and Chinese descent had it in much higher numbers than those of European descent, but it is very rare amongst women of African descent, which could help explain some of the differences in how different races respond to the disease. Perhaps in the future, scientists can find a way to use this information to boost the chances for those who lack this polymorphism.
