Nuchal ultrasound

I had a baby in December 2007 who was diagnosed with Noonan Syndrome. Unfortunately, she passed away shortly after. I am now pregnant again and just received a Nuchal translucency ultrasound. The findings were excellent. I was at the lowest risk possible, although it is a screening for Down Syndrome and some of the Trisomies. I have read several case studies notating a large nuchal reading corrolating with a postnatal diagnosis for Noonan syndrome. Does anyone have more info on this topic? Is this a good screening for THis syndrome and maybe there is not enough research yet? Any infor would be great!
