Genome-wide SNP genotyping and DNA methylation epigenotyping of African rainforest hunter-gatherers and neighbouring agriculturalists

ABSTRACT: The epigenomic landscape of the human genome, in particular DNA methylation, is increasingly recognised as an important driver of phenotypic diversity in health and disease. However, the impact that genetic variation and changes in lifestyle and ecological habitat have on this epigenetic mark remains unknown. To address this question, we analysed genome-wide SNP and DNA methylation profiles of 362 individuals from African populations of rainforest hunter-gatherers and sedentary farmers with different past and present lifestyles and ecologies.

The genetic history of African populations is increasingly well documented, yet their patterns of epigenomic variation remain uncharacterized. Moreover, the relative impacts of DNA sequence variation and temporal changes in lifestyle and habitat on the human epigenome remain unknown. Here we generate genome-wide genotype and DNA methylation profiles for 362 rainforest hunter-gatherers and sedentary farmers. We find that the current habitat and historical lifestyle of a population have similarly  ...[more]
