Angiotensinogen gene T235 variant: a marker for the development of persistent microalbuminuria in children and adolescents with type 1 diabetes mellitus

Abstract Aim We examined genetic polymorphisms in the renin–angiotensin system (RAS) coding for angiotensin I-converting enzyme ( ACE ) insertion/deletion ( I/D ) for angiotensinogen ( AGT ) M235T and angiotensin II receptor type 1 ( AGTR1 ) A1166C as predictors for the development of microalbuminur...

Kaplan–Meier survival curves and Cox proportional multivariate model estimated the probability of developing MA and the relative risk for MA among different variables. Results MA developed in 41 (9.1%) subjects. The frequencies of genotypes were as follows: ACE-II 112 (25%), ACE-ID 221 (49%), and ACE-DD 117 (26%) ( n =450); AGT-MM 144 (32%), AGT-MT 231 (51%), and AGT-TT 77 (17%) ( n =452); AGTR1-AA 211 (47%), AGTR1-AC 204 (45%), and AGTR1-CC 37 (8%) ( n =452).
