Moderate cytoplasmic positivity was observed in few cases of melanoma. Weak to moderate membranous staining was displayed mainly in colorectal cancer. Weak cytoplasmic positivity was detected in few cases of other cancer types.
GENE INFORMATION
Gene name
PRAME (HGNC Symbol)
Synonyms
CT130, MAPE
Description
Preferentially expressed antigen in melanoma (HGNC Symbol)
Entrez gene summary
This gene encodes an antigen that is preferentially expressed in human melanomas and that is recognized by cytolytic T lymphocytes. It is not expressed in normal tissues, except testis. The encoded protein acts as a repressor of retinoic acid receptor, and likely confers a growth advantage to cancer cells via this function. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2014]
