Abstract excerpt
AIMS: Mutations and epimutations in genes encoding the succinate dehydrogenase complex (SDHx) are associated with multiple tumour types in which identification of SDH-deficiency has significant management implications. Immunohistochemistry (IHC) for the succinate dehydrogenase B (SDHB) subunit can help to detect SDH-deficiency, which manifests as complete loss of staining in tumour cells. However, a subset of...
