Paired box gene 9, also known as PAX9, is a protein which in humans is encoded by the PAX9 gene.[1][2] It is also found in mammals generally.[3]


This gene is a member of the paired box (PAX) family of transcription factors. PAX9 is responsible for tooth development[3] and may more generally involve development of stratified squamous epithelia as well as various organs and skeletal elements.[1] PAX9 plays a role in the absence of wisdom teeth in some human populations (possibly along with the less well studied AXIN2 and MSX1).[3]

Clinical significance

This gene was found amplified in lung cancer. The amplification covers three tissue developmental genes - TTF1, NKX2-8, and PAX9.[4] It appears that certain lung cancer cells select for DNA copy number amplification and increased RNA/protein expression of these three coamplified genes for functional advantages.


PAX9 has been shown to interact with JARID1B.[5]
