Original sentence: First, the affected enzyme in most cases (StAR) is a transport protein rather than a steroidogenic enzyme.Second, because the defect is so proximal, all steroid synthesis is compromised and thus, there are no effects of excessive mineralocorticoids or androgens to be suppressed
Edited sentence: First, the affected gene in most cases is that for a transport protein (StAR) rather than a steroidogenic enzyme.Second, because the defect compromises all steroid synthesis.Thus, there are no problems due to excessive mineralocorticoids or androgens
