A total of 195 patients with multiple sclerosis (MS) and 126 controls were investigated for angiotensinogen/(-6)A/G, M235T/and angiotensin converting enzyme I/D gene polymorphisms to test their association with MS susceptibility and/or disease progression using Global Multiple Sclerosis Severity Score (MSSS). We demonstrated a significant association of M235T polymorphism with MSSS. The MM homozygotes had the lowest (3.8), heterozygotes MT higher (5.2) and homozygotes TT the highest (5.4) mean MSSS values (P=0.02). For polymorphisms (-6)A/G of ATG, only a trend was observed (P=0.06), where the homozygotes GG carried lower MSSS values than heterozygotes and homozygotes AA. No significant association with susceptibility was observed. For ACE I/D polymorphism, neither significant differences in the genotype-phenotype study nor in the case-control study were observed.
