TL;DR: In this article , the authors analyzed new autosomal genetic variation data of 1333 individuals from over 150 ethnic groups from Cameroon, Republic of the Congo, Ghana, Nigeria, and Sudan, and demonstrated a previously underappreciated fine-scale level of genetic structure within these countries, for example, correlating with historical polities in western Cameroon.

TL;DR: A review of the current insights derived from the analyses of new large-scale, genome-wide autosomal variation data studies incorporating Ethiopians can be found in this article, where the authors demonstrate how genetic analyses can complement findings from anthropological and linguistic studies on Ethiopians.

TL;DR: It is shown that Zoroastrian in Iran and India show increased genetic homogeneity relative to other sampled groups in their respective countries, consistent with their current practices of endogamy, and genomic regions showing signatures of positive selection in present-day Zoroastrians that might correlate to the prevalence of particular diseases amongst these communities are reported.

TL;DR: Moderate powered genome-wide association studies (GWAS) have enabled more than 20 additional risk loci to be identified and have shown that multiple variants exerting modest individual effects have a key role in disease susceptibility.

TL;DR: In this paper, the authors used the Illumina Exomechip microarray to compare 1504 cases with AS and AAU, 1805 with AS but no AAU and 21 133 healthy controls.
