Most cancers displayed moderate to strong cytoplasmic immunoreactivity with additional nuclear staining in some cases. A majority of gliomas were weakly stained or negative.
GENE INFORMATION
Gene name
PPOX (HGNC Symbol)
Synonyms
PPO, VP
Description
Protoporphyrinogen oxidase (HGNC Symbol)
Entrez gene summary
This gene encodes the penultimate enzyme of heme biosynthesis, which catalyzes the 6-electron oxidation of protoporphyrinogen IX to form protoporphyrin IX. Mutations in this gene cause variegate porphyria, an autosomal dominant disorder of heme metabolism resulting from a deficiency in protoporphyrinogen oxidase, an enzyme located on the inner mitochondrial membrane. Alternatively spliced transcript variants encoding the same protein have been identified. [provided by RefSeq, Jul 2008]
