Abstract:
DNA samples were collected from clinical well characterized MS patients, which attended our out-patients department for several years. First, we identified functional relevant gene polymorphisms in known immunoregulatory factors. The in vitro phenotypes of these mutations were investigated by appropriate functional tests and correlated to course of the disease, severity of symptoms and results of magnetic resonance images. First, we observed a correlation of the CTLA-4 (exon1+49) mutation with a reduced expression of this molecule on the surface of blood lymphocytes and chronic progressive disease course.
Furthermore, we looked for polymorphisms in neurotrophic factor genes and detected an association of a CNTF null mutation with early disease onset and severe course. Currently, we are establishing a new DNA collection of familiar MS cases together with Dr. B. Hemmer (Marburg).
