Abstract
Treacher Collins syndrome (TCS) is one of the rare genetic syndromes which is specified by symmetrical craniofacial dysmorphism without growth abnormalities or neurological disorders. The inheritance is usually autosomal dominant but sometimes it is a sporadic mutation. Prenatal diagnosis could be realized by genetic testing of a chorionic villus sample or amniocentesis if one of the parents is affected. At birth, the most common features are downward-sloping palpebral clefts, small badly hemmed and folded ears, and mandibular hypoplasia which could lead to respiratory distress. All of these clinical features exist in our case. Goldenhar syndrome shares with TCS some facial features which are not symmetrical and it is also associated with vertebral abnormalities. Some patients with TCS are exposed to many complications and they require multi-disciplinary medical care. But all of them need psychiatric care to fight social rejection. The aim of our report is to describe the most common features of TCS and similar syndromes. Also, report the involved genetic mutations, some associated complications, and their management.
