>Dear Dr. Porta,
Several months ago we had a similar case of mosaic in the amniotic fluid culture as the one you mentioned. I wonder if you had the chance (as we had) to perform a ultrasound early in first trimestrer. It could very well be a case of a "vanishing twin" as it was in our case. Does the pelvic U.S. scan of the fetus reveals anything? A cordocenteses could also be interesting to draw fetal blood to have a cariotype and see if the same two cellular lines are actually present in the baby. In our case we did that and to our incial surprise the baby was totally normal. Of course, if the mosaic remains in the fetal bloof it means it is a real Turner although a normal cariotype does not mean that it is not ( in our case the new born examination was normal) but even if it is the prognosis is much better, excluding sterility of course. After the babys's birth a pelvic U.S. scan or a CAT could be interesting as to inlight about the gonada and it would be helpfull also to have a skin biopsy. I would like to know the follow up of this case if you are so kind as to contact me again and give me this information. Sincerely yours,

Prof. Dr. Carlos Santos Jorge President of the Portuguese Society of Prenatal Diagnosis Dep. of Obstetrics and Maternal-fetal Medicine Institute of Biomedical Sciences University of Oporto, Portugal csjorge@mail2.esoterica.pt
