In meningiomas, over 10% of tumor cells in angiomatous meningioma expressed N-cadherin in 7/10 (70%) cases, whereas 3/10 meningothelial, 2/10 fibrous, and 1/10 atypical meningiomas revealed expression of N-cadherin in ≥10% of tumor cells (P = 0.001). The gene discussed is CDH2; the disease is meningioma.
