Treacher Collins syndrome (TCS) is a genetic disorder characterized by deformities of the ears, eyes, cheekbones, and chin.[5] The degree to which a person is affected, however, may vary from mild to severe.[5] Complications may include breathing problems, problems seeing, cleft palate, and hearing loss.[5] Those affected generally have normal intelligence.[5]

TCS is usually autosomal dominant.[5] More than half the time it occurs as a result of a new mutation rather than being inherited.[5] The involved genes may include TCOF1, POLR1C, or POLR1D.[5] Diagnosis is generally suspected based on symptoms and X-rays, and potentially confirmation by genetic testing.[3]

Treacher Collins syndrome is not curable.[6] Symptoms may be managed with reconstructive surgery, hearing aids, speech therapy, and other assistive devices.[6] Life expectancy is generally normal.[6] TCS occurs in about one in 50,000 people.[5] The syndrome is named after Edward Treacher Collins, an English surgeon and ophthalmologist, who described its essential traits in 1900.[7][8]
