RELA and supratentorial ependymoma: Recently, a specific translocation was identified in around 2/3 of supratentorial ependymoma in children, involving the genes RELA (v‐rel avian reticuloendotheliosis viral oncogene homolog A) and C11orf95, resulting in an oncogenic fusion gene, leading to nuclear translocation of p65‐RelA protein and pathological activation of NFκB signaling.
