[Immunogenetic markers of disseminated sclerosis in western Siberia].

The contents of class 1 HLA antigens was compared in patients with disseminated sclerosis, their first-grade relatives and healthy donors. Patients, as compared to healthy persons, had higher occurrence rate of A1, A9, B7, A0/B0, A9/B7, A1/B7, A1/B12, A2/B7, B7, 27, B5, 0, B7, 12, B7, 15, B5, 7, and lower A28, B13, Bw22, B35, 40, B7, 35, A2, w19, A0/B35, A0/B13, A2/B15, A3/B35. In male patients, as compared to female patients, B40 and A1/B15 were more frequent, and B12 less frequent. The subgroup of patients with the diseases onset before 20 years considerably differed from other patients in their rates of A1, A1, 2, A1w19, A1/B0 increased and A3 and A9/B17 decreased. Compared to donor group, the patients' relatives had differences similar to those between patients and relatives. High relative risk values were characteristic of some of the above associations.
