Summaries for PAX8 Gene

Entrez Gene Summary 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]

GeneCards Summary for PAX8 Gene

PAX8 (Paired Box 8) is a Protein Coding gene. Diseases associated with PAX8 include hypothyroidism, congenital, due to thyroid dysgenesis or hypoplasia and nephrogenic adenoma of urinary bladder. Among its related pathways are Pathways in cancer and Transcriptional misregulation in cancer. GO annotations related to this gene include sequence-specific DNA binding transcription factor activity and RNA polymerase II core promoter sequence-specific DNA binding. An important paralog of this gene is PAX4.

(1) OMIM Diseases for PAX8 Gene (167415)


  • Hypothyroidism, congenital, non-goitrous, 2 (CHNG2) [MIM:218700]: A disease characterized by thyroid dysgenesis, the most frequent cause of congenital hypothyroidism, accounting for 85% of case. The thyroid gland can be completely absent (athyreosis), ectopically located and/or severely hypoplastic. Ectopic thyroid gland is the most frequent malformation, with thyroid tissue being found most often at the base of the tongue. {ECO:0000269 PubMed:11232006, ECO:0000269 PubMed:11502839, ECO:0000269 PubMed:9590296}. Note=The disease is caused by mutations affecting the gene represented in this entry.
