Angiotensin-converting enzyme I/D gene polymorphism and risk of multiple sclerosis

Objectives - Angiotensin-converting enzyme (ACE) activity is increased in blood and cerebrospinal fluid of patients with multiple sclerosis (MS). In addition, in experimental autoimmune encephalomyelitis (EAE), an animal model of MS, the blockade of ACE suppresses the disease itself. To analyze the genetic association of the ACE gene with MS, we examined ACE gene insertion/deletion (I/D) polymorphism in MS patients. Materials and methods - A total of 313 MS patients from Slovenia and Croatia and 376 healthy controls were genotyped by polymerase chain reaction method. Results - We found statistically significant differences in the distribution of ACE I/D allele frequencies (P<0.01) and genotypes (P<0.04) in male patients. ACE DD genotype was associated with MS in men at an odds ratio of 1.86 (95% CI 1.09-3.19, P=0.02). Conclusions - DD genotype of ACE gene might contribute to a higher risk of developing MS in men.
