The genotype distributions of AT1R A1166C polymorphism in genetic model AA vs. AC (OR = 1.31; 95% CI = 0.14-11.78; p < 0.867) and allelic model A vs. C (OR = 1.29; 95% CI = 0.15-11.2; p < 0.811) were not found to be significantly associated between the non-hypertensive and hypertensive groups of ADPKD. This evidence concerns the gene AGTR1 and autosomal dominant polycystic kidney disease.
