okay... is an enzyme deficiency... but do get it under this scenario as well, bc most of time BUZZWORDS are not thereraised eyebrow lets try it now

  #11

17-hydroxylase def?

  #12

Good job me007 ! wink
Excellent and do remember this wild scenario !!!

  #13

17 hydroxylase enzyme NOT expressed in Z glomerulosa, only expressed in Z fascic, retic---> Cortisol down, Androgens down----> incr ACTh---> adrenal hyperplasia and incr in all products before blockade----> incr 11 DeoxyCorticosterone= weak mineralocorticoid ( im sure you guys love this 11 DeoxyCorticosterone by now grin) --> this is responsible for HTN---> decr Renin--->decr AII---> wich is the main stimulus for Z glomerulosa----> therefore Aldosterone secr DOWN
