Angiotensin type 2 receptor is important in the normal development of the ureter

1999

In humans, the actions of angiotensin II are transduced through the AT1 and AT2 receptors which have recently been implicated in renal organogenesis. Polymorphisms in the human angiotensin II receptor genes have been linked to cardiovascular and nephrological disorders. In this study we evaluated 35 patients with either primary obstructive megaureter or posterior urethral valves. Each was genotyped for the A1166 AT1 polymorphism and the recently described A-1332G AT2 transition. The incidence of these genetic variants was also evaluated in normal controls without any ultrasonographic urological abnormalities. Similar to our previous findings in congenital urological abnormalities, the AT1 r…
