title: Incomplete prenatal diagnosis of G-trisomy mosaicism.
abstract: Chromosomal mosaicism is difficult to detect in prenatal diagnosis, and it seems even more difficult to predict its significance correctly. We present a case, in which G-trisomy mosaicism was diagnosed prenatally but was not verified in the aborted fetus. A practical approach to suspected fetal mosaicism in prenatal diagnosis is proposed.
