However, the possible influence of other genetic factors is still under debate. This study investigated the role of the a 1-antichymotrypsin (ACT) gene as a susceptibility factor for developing late-onset AD in the population of Navarra.Patients and methodsThe study group included 98 patients with late-onset AD and 188 control individuals 70-71 years of age. APOE*epsilon2,*epsilon3,*epsilon4 and ACT codon -17*A,*T polymorphisms were analyzed by PCR-RFLP. Statistical analyses were performed determining the chi-square test, using 2 x 2 contingency tables and logistic regression to calculate odds ratios.ResultsAPOE*epsilon4 allele frequency was significantly higher in AD patients than in controls (odds ratio [OR] = 3.02; 95% confidence interval [CI], 1.59-5.73; p < 0.001 in heterozygous carriers, and OR = 9.40; 95% CI, 1.84-64.43; p = 0.001 in homozygous individuals). We found no significant differences in the distribution of ACT polymorphisms between AD cases and controls. However, APOE*epsilon4 carriers had a 2.5-fold increased risk of developing AD in the presence of the ACT/AA genotype (OR = 10.13; 95% CI, 1.98-97.81; p < 0.001). The risk difference, however, did not reach statistical significance (p = 0.271).ConclusionsAPOE*epsilon4 heterozygous and homozygous carriers have a 3 and 9 times higher risk, respectively, of developing AD. We could not demonstrate an effect of ACT polymorphisms as a independent risk factor for this disease; however, the ACT/AA genotype seems to act as an additional susceptibility factor, duplicating the APOE*epsilon4-associated AD risk."xsd:string |
