During this treatment at our hospital, the levels of serum sarcoidosis markers of angiotensin-converting enzyme (ACE) and soluble interleukin-2 receptor (sIL-2R) were 7.8 U/L (normal range: 8.321.4 U/L) and 3550 U/mL (normal range: 154–474 U/mL) at the highest point, respectively, suggesting enhanced activity of sarcoidosis. The gene discussed is ACE; the disease is sarcoidosis.
