Population substructure of the study participants. (Top Panel) STRUCTURE analysis for 10,295 autosomal markers for eight ancestral populations and including the 68 Black (50 cases and 18 controls) and 84 Coloured South African (SA) study participants compared with African Americans and reference populations from Africa (Ju/‘hoansi, Mandinka, Yoruba, Bamoun, Fang and Luhya) and outside of Africa (European and Han Chinese) for a total of 397 subjects. (Middle Panel) Using STRUCTURE analysis we determined the African ancestral fractions, defined as KhoeSan, West/Proto-Bantu, East Bantu and Southern Bantu, as well as the non-African ancestral fractions, defined as European and Eurasian, within our study cohort with comparisons made with the African Americans
