Treacher Collins syndrome is inherited in an autosomal-dominant pattern. Mutations in TCOF1, POLR1C, or POLR1D genes can cause Treacher Collins syndrome. [17] TCOF1 gene mutations are the most common cause of the disorder, with POLR1C and POLR1D gene mutations causing an additional 2% of cases. In individuals without an identified mutation in ...
Researchers have found that most patients with Treacher Collins syndrome have symmetric external ear canal abnormalities and symmetrically dysmorphic or absent ossicles in the middle ear space. Inner ear structure is largely normal. Most patients show a moderate hearing impairment or greater, and the type of loss is generally a conductive ...

More than 120 mutations in the TCOF gene have been identified in people with Treacher Collins syndrome. Most of these mutations insert or delete a small number of DNA building blocks in the TCOF1 gene. TCOF1 mutations lead to the production of an abnormally small, nonfunctional version of treacle or prevent the cell from producing this protein.
