Treacher Collins syndrome (TCS, also called mandibulofacial dysostosis and Franceschetti-Klein Syndrome) is a genetic condition involving underdevelopment of the structures of the head and face caused by a mutation in the genes on chromosome 5 (FACES, September 8, 1999) The child affected by Treacher Collins Syndrome can experience a cognitive delay. Cognition is the process of understanding or acquiring knowledge. A child can learn and understand the surroundings with thoughts, senses, and experiences. When the child experiences cognitive delays, it leads to failure in reaching developmental milestones Treacher Collins syndrome and anauxetic dysplasia demonstrate that defects in ribosome synthesis can cause clinical syndromes that do not include bone marrow failure. Moreover, the pathologies observed in X-linked DC and CHH appear to be predominantly consequences of extraribosomal functions of each affected gene product
