To investigate whether there is an association between (–6)A/G a M235T polymorphisms of angiotensinogen (ATG) and susceptibility to multiple sclerosis and/or the course of the disease.

Materials and methods:
A total of 195 patients (49 men and 146 women) with multiple sclerosis (MS) and 126 healthy controls were investigated for two angiotensinogen polymorphisms using PCR and restriction analysis. The data were analysed with the support Statistica software, version 8.0 (StratSoft, Inc., Tulsa, OK, USA) and using the Fisher’s, Chi-squared and Holm’s tests.

We observed no significant differences in genotype or allelic distribution between groups of patients and control subjects for tested ATG polymorphisms. Double homozygotes MMGG were less frequent in the group of MS patients (p = 0.029, Odds ratio = 0.57, CI 0.33–0.98). However, using the Holm’s test for multiple comparisons, the results lacked statistical significance (pcorr= 0.17). We did not find significant differences either in genotype distribution or in allele frequencies among MS patients with the different disease courses.

Our study did not find an association between (–6)A/G a M235T polymorphisms of ATG and susceptibility to multiple sclerosis or the course of this disease.
