Associated Diseases (KEGG IDs)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}. The disease is caused by mutations affecting the gene represented in this entry.
General Description of Pax-8 .
PAX 8 is expressed in a high percentage of renal cell carcinomas and ovarian cancers. This mouse monoclonal PAX 8 antibody [4H7B3] has been designed to target restricted epitopes, and exhibits higher specificity and provides sharper staining than the PAX 8 rabbit polyclonal antibody. Unlike the polyclonal PAX 8, this mouse monoclonal antibody does not stain B-cells, and does not recognize epitopes of pancreatic origin and neuroendocrine cells in stomach and colon; thus providing superior specificity. The expression of the mouse monoclonal PAX 8 targets antigens found in normal kidney, thyroid and cervix, but not normal ovary. PAX 8 stains nuclei exclusively and performs well in formalin-fixed paraffin-embedded tissues.

Pax-8 Information for Pathologists


Also called Paired box 8. Discovered in 1990 (Development 1990;110:643). Paired domains are composed of two helix-turn-helix subdomains. The N-terminal subdomain and the C-terminal subdomain, both of which can bind DNA independently (Cell 1995;80:639). Structurally similar to PAX2 and PAX5.

Common Uses By Pathologists:

Differentiate PAX8+ primary or metastatic tumors (kidney, Müllerian [but not mucinous, Am J Surg Pathol 2011;35:1837], thymic, thyroid) from PAX8- tumors (adrenal, breast, GI [most], lung, prostate, Am J Surg Pathol 2011;35:816). Differentiate prostatic mesonephric remnant hyperplasia (PAX8+) from prostatic adenocarcinoma (PAX8-, Am J Surg Pathol 2011;35:1054). Differentiate metastatic clear cell renal cell carcinoma (PAX2+ or PAX8+ / inhibinA neg) from hemangioblastoma (PAX2-, PAX8-, inhibin A+, Am J Surg Pathol 2011;35:262). Differentiate endosalpingiosis in axillary lymph nodes (PAX8+ / WT1+) from metastatic breast carcinoma (PAX8-, WT1-, Am J Surg Pathol 2010;34:1211). Differentiate renal collecting duct carcinoma (PAX8+ / p63-) from urothelial carcinoma of upper urinary tract (PAX8- / p63+, Am J Surg Pathol 2010;34:965).
