title: Association between apolipoprotein E4 genotype and human immunodeficiency virus-associated dementia in younger adults starting antiretroviral therapy in South Africa.
abstract: It is not known whether the apolipoprotein E (ApoE) &#x03B5;4 allelic variant is associated with human immunodeficiency virus (HIV)-associated dementia (HAD) in a South African population, where HIV clade C is predominant. ApoE genotyping was performed on 144 participants in a larger study of HIV-associated neurocognitive disorders (HAND). There was a lower frequency of the &#x03B5;2 and &#x03B5;3 alleles in the HIV-positive group, compared to a group of 300 community-based newborn infants. There were no differences in ApoE genotype across different categories of HAND. The &#x03B5;4 allelic variant was less common in individuals with HAD than in those without HAD. These findings suggest that the &#x03B5;4 allelic variant in HIV-positive individuals is not associated with the development of HAD in Southern Africa.
