Graph of first 2 principle components of autosomal genome-wide AIMs among Crohn’s disease (black triangles), ulcerative colitis (black crosses), and indeterminate colitis (black diamonds) cases, and healthy controls (black circles), all self-described as African Americans, relative to positions of HapMap populations as follows: CEU, Utah residents with Northern and Western European ancestry; CHD, Chinese in Denver, CO; YRI, Yoruba in Ibadan, Nigeria; CHB, Han Chinese in Beijing, China; JPT, Japanese in Tokyo, Japan; LWK, Luhya in Webuye, Kenya; ASW, African Americans in the Southwest USA (all having 4 grandparents also identified as African American); MXL, Mexican ancestry in Los Angeles, CA; TSI, Toscani in Italy; GIH, Gujarati Indians in Houston, TX; MKK, Maasai in Kinyawa, Kenya.
