ABO blood type is associated with cardiovascular disease, although the underlying mechanisms are presumed to be complex. While the relationship between non-O blood types and von Willebrand Factor (vWF) is well-established, associations with cellular adhesion molecules (CAMs) across diverse populations are understudied. We genetically inferred ABO alleles for N = 6202 participants from the Multi-Ethnic Study of Atherosclerosis. Linear regression was used to evaluate associations between major ABO allele dosages and log-transformed measurements of vWF (N = 924), soluble E-selectin (sE-selectin, N = 925), soluble P-selectin (sP-selectin, N = 2392), and soluble ICAM-1 (sICAM-1, N = 2236) by race/ethnicity. For the selectins, the A1 allele was associated with significantly lower levels for all races/ethnicities, with each additional allele resulting in a 28–39% decrease in sE-selectin and 10–18% decrease in sP-selectin relative to Type O subjects. However, the A2 allele demonstrated effect heterogeneity across race/ethnicity for sE-selectin, with lower levels for non-Hispanic whites (p = 0.0011) but higher levels for Hispanics (p = 0.0021). We also identified elevated sP-selectin levels for B-allele carriers solely in Hispanic participants (p = 1.0E-04). ABO-by-race/ethnicity interactions were significant for both selectins (p < 0.0125). More modest associations were observed between A1 allele dosage and levels of sICAM-1, with ABO alleles explaining 0.8–1.1% of the total phenotypic variation within race/ethnicity. ABO associations with vWF activity were consistent across race/ethnicity, with B allele carriers corresponding to the highest vWF activity levels. ABO blood type demonstrates complex associations with endothelial markers that are largely generalizable across diverse populations. •ABO blood type and adhesion markers are understudied in diverse populations.•We study ABO and vWF, sE-selectin, sP-selectin, and sICAM-1 in four races/ethnicities.•ABO-protein associations are largely generalizable across populations.•Associations with sP-selectin and sE-selectin demonstrate racial/ethnic heterogeneity.
