Gene Mutation Results In Missing Teeth

Summary:
Approximately 20 percent of the population are born unable to develop a full set of teeth. Although the underlying causes are mostly unknown, members of a Houston, Texas family who lack mainly their first and second molars were found to have a mutation in a gene called PAX9. This is the first report of a human disorder linked to PAX9, one of a family of "master" genes that help determine body shape and organ formation during embryological development.

Approximately 20 percent of the population are born unable to develop a full set of teeth. Although the underlying causes are mostly unknown, members of a Houston, Texas family who lack mainly their first and second molars were found to have a mutation in a gene called PAX9. This is the first report of a human disorder linked to PAX9, one of a family of "master" genes that help determine body shape and organ formation during embryological development. This discovery is an important contribution to understanding the genetics of human tooth development and brings scientists a step closer to someday replicating the process.
