From: ATRX immunostaining predicts IDH and H3F3A status in gliomas
ATRX immunohistochemistry: a loss of immunoreactivity in necrotic/perinecrotic tumor areas, b Ambiguous ATRX status; areas with clear ATRX retention bordering areas with nuclear ATRX loss. c Diffuse astrocytoma grade II with ATRX loss, d Anaplastic Astrocytoma grade III with ATRX loss, e Oligodendroglioma grade II with ATRX retention, f Anaplastic Ependymoma with ATRX retention (f magnification ×200, a, c–e magnification ×100, b magnification ×40)
