TL;DR: It is shown that modern imputation panels (sets of reference genotypes from which unobserved or missing genotypes in study sets can be inferred) can identify association signals at highly differentiated loci across populations in sub-Saharan Africa.
Journal ArticleDOI

TL;DR: If the dearth of genomics research involving Africans persists, the potential health and economic benefits emanating from genomic science may elude an entire continent.
Journal ArticleDOI

TL;DR: A comparison of the rates of substitution in genes in the melanocortin receptor family indicates that MC1R has evolved the fastest, and the nucleotide diversity at theMC1R locus is shown to be several times higher than the average nucleotide Diversity in human populations, possibly due to diversifying selection.
