Tissue typing was used to study characteristic features of class I and II HLA-antigens distribution in two populations of young IHD patients: Russians (n-32) and Georgians (n-72). Healthy donors (267 Russians and 579 Georgians) served as controls. Genetic markers of IHD predisposition are revealed: for Russians relative risk for B12, DR1 equaled 2.95 and 3.65, respectively, and for Georgians 6.60, 3.02 and 2.33 for B21, Bw22 and DR2, respectively. The differences in markers of IHD predisposition in two populations belonging to the same race suggest than IHD predisposition gene in each population may be bound to various HLA antigen(s). This necessitates study of the markers not only in each race, but in each population as well.
