Merlin immunohistochemistry is a reliable surrogate marker for NF2 gene alterations in meningioma

Histopathology, EarlyView.
This study found that complete loss of Merlin immunostaining could serve as a reliable surrogate marker for NF2 gene alterations in low‐grade meningioma. We also introduce some pitfalls in the interpretation of its staining pattern. Aims Molecular characterization as well as histologic grading has proven useful in predicting the biological behaviour of
