Clinical Information
  • A hereditary disorder occurring in two forms: the complete form (franceschetti's syndrome) is characterized by antimongoloid slant of the palpebral fissures, coloboma of the lower lid, micrognathia and hypoplasia of the zygomatic arches, and microtia. It is transmitted as an autosomal trait. The incomplete form (treacher collins syndrome) is characterized by the same anomalies in less pronounced degree. It occurs sporadically, but an autosomal dominant mode of transmission is suspected. (Dorland, 27th ed)
  • A rare autosomal dominant syndrome caused by mutations in the tcof1 gene. Its characteristics include underdevelopment of the facial bones, small jaw and chin, absent or small ears, defects in the middle ear resulting in hearing loss, and downward sloping palpebral fissures.
  • A syndrome with variable expressivity, largely involving structures derived from the first pharyngeal arch, groove or pouch. It is characterized mainly by fishlike facies with receding chin, downward sloping palpebral fissures, colobomas of the eyelids, macrostomia, dysplastic ears, and other anomalies. Ear malformation are usually associated with hearing loss. Orofacial defects are symmetrical and differ from those in oculo-auriculovertebral dysplasia which generally affect one side of the body. Mental retardation occurs in some cases. The name treacher collins is sometimes erroneously hyphenated.
Present On Admission
POA Help
"Present On Admission" is defined as present at the time the order for inpatient admission occurs — conditions that develop during an outpatient encounter, including emergency department, observation, or outpatient surgery, are considered POA.
