Summaries for Treacher Collins Syndrome 1

About this section
NIH Rare Diseases:45 Treacher collins syndrome (tcs) is a condition that affects the development of bones and other tissues of the face. the signs and symptoms vary greatly, ranging from almost unnoticeable to severe. most affected people have underdeveloped facial bones, particularly the cheek bones, and a very small jaw and chin (micrognathia). other features may include cleft palate, eye abnormalities, and hearing loss. tcs may be caused by mutations in the tcof1, polr1c, or polr1d genes. when the tcof1 or polr1d gene is responsible, it is inherited in an autosomal dominant manner. however, about 60% of autosomal dominant cases are due to a new mutation in the gene and are not inherited from a parent. when the polr1c gene is responsible, it is inherited in an autosomal recessive manner. in some cases, the genetic cause of the condition is unknown. last updated: 11/11/2015

MalaCards based summary: Treacher Collins Syndrome 1, also known as treacher collins syndrome, is related to acrofacial dysostosis 1, nager type and mandibulofacial dysostosis, guion-almeida type, and has symptoms including malar flattening, small face and micrognathia. An important gene associated with Treacher Collins Syndrome 1 is TCOF1 (Treacle Ribosome Biogenesis Factor 1), and among its related pathways are TNF-alpha/NF-kB Signaling Pathway and Assembly of RNA Polymerase-I Initiation Complex. Affiliated tissues include bone, eye and testes, and related mouse phenotypes are craniofacial and skeleton.

Genetics Home Reference:23 Treacher Collins syndrome is a condition that affects the development of bones and other tissues of the face. The signs and symptoms of this disorder vary greatly, ranging from almost unnoticeable to severe. Most affected individuals have underdeveloped facial bones, particularly the cheek bones, and a very small jaw and chin (micrognathia). Some people with this condition are also born with an opening in the roof of the mouth called a cleft palate. In severe cases, underdevelopment of the facial bones may restrict an affected infant's airway, causing potentially life-threatening respiratory problems.

UniProtKB/Swiss-Prot:67 Treacher Collins syndrome 1: A form of Treacher Collins syndrome, a disorder of craniofacial development. Treacher Collins syndrome is characterized by a combination of bilateral downward slanting of the palpebral fissures, colobomas of the lower eyelids with a paucity of eyelashes medial to the defect, hypoplasia of the facial bones, cleft palate, malformation of the external ears, atresia of the external auditory canals, and bilateral conductive hearing loss.
