title: SCE, X-radiation sensitivity and mutation rate in multiple sclerosis.
abstract: In order to detect any underlying DNA abnormality that may be present in multiple sclerosis (MS), the incidence of SCE, X-radiation sensitivity and the frequency of 6-thioguanine-resistant cells were determined in the lymphocytes of 34 MS patients. As a group, MS patients showed an increase in the SCE rate compared to control. However, there was no increase in X-radiation sensitivity. The frequency of 6-thioguanine-resistant mutant cells was also normal.
