Immunohistochemical assays of the epithelial membrane antigen (EMA), S100, vimentin, KI67, creatine kinase (CK), Leber congenital amaurosis (LCA), CD68, antibodies against glial fibrillary acidic protein (GFAP), BCL2, anaplastic lymphoma kinase (ALK), and synaptophysin levels were performed. Here, GFAP is linked to Leber congenital amaurosis.
