Previous GeneCards Identifiers for PAX8 Gene
This gene encodes a member of the paired box (PAX) family of transcription factors. Members of this gene family typically encode proteins that contain a paired box domain, an octapeptide, and a paired-type homeodomain. This nuclear protein is involved in thyroid follicular cell development and expression of thyroid-specific genes. Mutations in this gene have been associated with thyroid dysgenesis, thyroid follicular carcinomas and atypical follicular thyroid adenomas. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Mar 2010]
PAX8 is one of nine transcription factors within the PAX gene family. It has been observed to be expressed during embryonic development however expression attenuates after development in all but a few tissues. Research has indicated that over-expression of PAX proteins in general are not an initiating event in tumorgenesis however they may facilitate malignant development. PAX8 is expressed in 80-96% of all High-grade serous carcinomas (HGSC) and is commonly used as a marker for the disease. In addition PAX8 has become a useful biomarker for differentiating between mullerian mucinous and non-mullerian tumors. PAX8 has also been associated with neoplasms in the kidney and thyroid.
