His height corresponds to the 99th percentile for his age, and pubic hair is present upon physical examination. Serum renin and potassium levels are high, as is 17-hydroxyprogesterone. Which of the following is likely deficient in this patient?? A: 17a-hydroxylase, B: 11ß-hydroxylase, C: 21-hydroxylase, D: Aromatase, E: 5a-reductase,  <response>: This is a clinical vignette describing a 5-year-old boy with signs of precocious puberty, including tall stature, pubic hair development, and elevated renin and potassium levels. The high 17-hydroxyprogesterone level indicates a defect in steroidogenesis. The key finding is the combination of precocious puberty and elevated 17-hydroxyprogesterone, which points to a deficiency in 21-hydroxylase, an enzyme required to synthesize cortisol and aldosterone. Deficiencies in the other enzymes listed can result in varying clinical presentations, but 21-hydroxylase deficiency best matches this vignette.C: 21-hydroxylase
