Individuals with multiple sclerosis (MS) are assumed to have one or more populations of dividing T cells that are being stimulated by autoantigens. Mutant T cell clones from MS patients were isolated and tested for reactivity to myelin basic protein, an antigen that is thought to participate in the induction of the disease. The hypoxanthine guanine phosphoribosyltransferase (\n            <jats:italic>hprt<\/jats:italic>\n            ) clonal assay was used to determine mutant frequency values in MS patients with chronic progressive disease.
