Abstract Summary

Genome-wide study of 6,578 women identifies genetic variants at ICAM1 and ABO loci strongly associated with circulating sICAM-1 levels, a biomarker linked to heart attack, stroke, and diabetes. Notably, the ABO blood group locus showed the strongest association, revealing a previously unknown role of blood type antigens in regulating inflammatory adhesion processes.

Why Brain? 🧠

Large genetic study of 6,578 women reveals ABO blood type affects levels of sICAM-1, an inflammatory marker linked to heart attack, stroke, and diabetes, suggesting blood type influences inflammation.
