Description: Host-parasite coevolution has been likened to a molecular arms race, with particular parasite genes evolving to evade specific host defenses. Study of the variants of an antigenic epitope of Plasmodium falciparum that induces a cytotoxic T cell response supports this view. In African children with malaria, the variants present are influenced by the presence of a human leukocyte antigen (HLA) type that restricts the immune response to this epitope. The distribution of parasite variants may be further influenced by the ability of cohabiting parasite strains to facilitate each other's survival by down-regulating cellular immune responses, using altered peptide ligand antagonism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gilbert, S C -- Plebanski, M -- Gupta, S -- Morris, J -- Cox, M -- Aidoo, M -- Kwiatkowski, D -- Greenwood, B M -- Whittle, H C -- Hill, A V -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1998 Feb 20;279(5354):1173-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Centre for Human Genetics, Nuffield Department of Medicine, University of Oxford, Windmill Road, Oxford OX3 7BN, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9469800" target="_blank"〉PubMed〈/a〉

Description: Given the importance of Africa to studies of human origins and disease susceptibility, detailed characterization of African genetic diversity is needed. The African Genome Variation Project provides a resource with which to design, implement and interpret genomic studies in sub-Saharan Africa and worldwide. The African Genome Variation Project represents dense genotypes from 1,481 individuals and whole-genome sequences from 320 individuals across sub-Saharan Africa. Using this resource, we find novel evidence of complex, regionally distinct hunter-gatherer and Eurasian admixture across sub-Saharan Africa. We identify new loci under selection, including loci related to malaria susceptibility and hypertension. We show 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. Using whole-genome sequencing, we demonstrate further improvements in imputation accuracy, strengthening the case for large-scale sequencing efforts of diverse African haplotypes. Finally, we present an efficient genotype array design capturing common genetic variation in Africa.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4297536/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4297536/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gurdasani, Deepti -- Carstensen, Tommy -- Tekola-Ayele, Fasil -- Pagani, Luca -- Tachmazidou, Ioanna -- Hatzikotoulas, Konstantinos -- Karthikeyan, Savita -- Iles, Louise -- Pollard, Martin O -- Choudhury, Ananyo -- Ritchie, Graham R S -- Xue, Yali -- Asimit, Jennifer -- Nsubuga, Rebecca N -- Young, Elizabeth H -- Pomilla, Cristina -- Kivinen, Katja -- Rockett, Kirk -- Kamali, Anatoli -- Doumatey, Ayo P -- Asiki, Gershim -- Seeley, Janet -- Sisay-Joof, Fatoumatta -- Jallow, Muminatou -- Tollman, Stephen -- Mekonnen, Ephrem -- Ekong, Rosemary -- Oljira, Tamiru -- Bradman, Neil -- Bojang, Kalifa -- Ramsay, Michele -- Adeyemo, Adebowale -- Bekele, Endashaw -- Motala, Ayesha -- Norris, Shane A -- Pirie, Fraser -- Kaleebu, Pontiano -- Kwiatkowski, Dominic -- Tyler-Smith, Chris -- Rotimi, Charles -- Zeggini, Eleftheria -- Sandhu, Manjinder S -- 090770/Wellcome Trust/United Kingdom -- G0600718/Medical Research Council/United Kingdom -- G0801566/Medical Research Council/United Kingdom -- G0901213-92157/Medical Research Council/United Kingdom -- MR/K013491/1/Medical Research Council/United Kingdom -- P20 MD006899/MD/NIMHD NIH HHS/ -- WT077383/Z/05/Z/Wellcome Trust/United Kingdom -- Z01 HG200362-01/Intramural NIH HHS/ -- Z01HG200362/HG/NHGRI NIH HHS/ -- ZIA HG200362-02/Intramural NIH HHS/ -- ZIA HG200362-03/Intramural NIH HHS/ -- ZIA HG200362-04/Intramural NIH HHS/ -- ZIA HG200362-05/Intramural NIH HHS/ -- ZIA HG200362-06/Intramural NIH HHS/ -- England -- Nature. 2015 Jan 15;517(7534):327-32. doi: 10.1038/nature13997.
