PAX9

Paired box gene 9, also known as PAX9, is a human gene which is also found in mammals generally.

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