Hi, I'm new here.. Last Tuesday, 11 weeks nuchal scan showed a big 5mm translucency and we got 50:50 chance for 13, 18 or 21 cromosome abnormality. Decided to do cvs and the last week has been an absolute torment waiting for result. We were now called back and said that these three cromosomes plus the sex cromosome are normal and we would be referred to an urgent heart scan for the baby. However, the fetal medicine expert told us a week ago the heart sounded fine and now we would like to know what are the other possible genetic abnormalities that cause this kind of nuchal increase. The full report takes two weeks, but I would be very happy if you could possibly advice us what to brace ourselves to. Sorry I'm babbling, it's been just horrible..
