Treacher Collins Syndrome is believed to be caused by a change in the gene on chromosome 5, which affects facial development. About 40 percent of the time, one parent has the Treacher Collins Syndrome gene. Geneticists can now determine whether the Treacher Collins gene is a new mutation or one that has been passed on. There are new studies being done to see about the possibilities of there being other genes that could be involved with this syndrome.
