Paired box gene 8, also known as PAX8, is a protein which in humans is encoded by the PAX8 gene.[1]


This gene is a member of the paired box (PAX) family of transcription factors. Members of this gene family typically encode proteins which 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. Also functions in very early stages of kidney organogenesis, the mullerian system, and the thymus.[2]

Clinical significance

Mutations in this gene have been associated with thyroid dysgenesis, thyroid follicular carcinomas and atypical follicular thyroid adenomas. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.[1] A fusion protein, PAX8-PPAR-γ, is implicated in some follicular thyroid carcinomas and follicular-variant papillary thyroid carcinoma.[3]


PAX8 has been shown to interact with NK2 homeobox 1.[4]
