Inherited Treacher-Collins syndrome in twins after artificial insemination.

We present two cases of the Treacher-Collins syndrome and one case of plagiocephalus in a trigeminus childbirth resulting from artificial insemination. The mother, although affected with the Treacher-Collins syndrome, was not diagnosed before the birth of her children. Genetic counseling did not occur. Medical and forensic problems resulting from modern techniques of reproduction are briefly discussed.
