Figure 1. PIK3CA gene copy number detected by qPCR in different subtypes of pituitary adenomas. Positive amplification is defined as ≥4 copies. ACTH = adrenocorticotropic hormone-secreting adenoma; GH = growth hormone-secreting macroadenoma; PRL = prolactin-secreting macroadenoma; NF = nonfunctioning pituitary adenoma.
