People with HIV (14,013) and 112,132 matched people without HIV were included in a genome-wide association study, an observational search across DNA for variants linked to dementia. The researchers used All of Us Research Program data and adjusted the analysis for age, sex, race, ethnicity and genetic ancestry.
Three variants met the study’s strict statistical threshold in the combined sample and among people without HIV. Among people with HIV, three other variants showed suggestive links that fell short of that threshold. The analysis also identified 143 statistically significant interactions between genetic variants and HIV status, meaning that variants’ links to dementia differed according to whether people had HIV.
Why it matters
For dementia, an age-related condition, the authors suggest these genetic clues could help identify high-risk people with HIV and inform prevention strategies.
Caveats
The three links identified within the HIV group were suggestive rather than genome-wide significant. The analysis did not test whether these genetic findings could improve risk prediction or dementia prevention.
