Steroid metabolites revealed significant abnormalities of the renin‐angiotensin‐aldosterone axis, as well as of pituitary‐adrenal function. Analysis of our patient's DNA showed only one deleterious CYP21 mutation, an intron 2 base pair change activating a cryptic splice site. We speculate that expression of this patlent's CYP21 genes may be altered by the effects of ageing or by changes in the steroid
