Treacher Collins Syndrome
Treacher Collins syndrome (TCS) is a genetic disease that alters the development of bones and other tissues in the face, and presents variable expressivity. At least three genes TCOF1, POLR1D, and POLR1C were recognized to be at the origin of this syndrome which may be inherited through either an autosomal dominant or autosomal recessive pattern. TCS changes can be divided into otological, opht...

متن کاملTreacher- Collins Syndrome unusually in siblings
TreacherCollins Syndrome (TCS) is a rare autosomal dominant disorder of craniofacial morphogenesis. The frequency of TCS is 1 in 50,000 live births. Approximately half of cases arise as a result of sporadic mutation; the rest are familial. TCS is caused by a mutation in a TCOFI gene on chromosomes 5q31.3-32. The severely affected persons show classic physical characteristics and mildly affected...
