I am so sorry for your friend and hope that baby stays in and cooks.
My DS had a spot on his heart at my 20 week ultrasound and I was also told it was a downs marker and to get a level 2 ultrasound at the hospital. The doctor who did the ultrasound confirmed that was the only marker, but was saying the only way to know for sure is to have an amnio, which I did not want to do. I ended up switching to another doctor in the practice after the two ultrasounds and my new doctor said your baby is fine, you do not need an amnio, and it is probably an echogenic focus, which is a calcium deposit. The spot was gone at my 36 week ultrasound and DS is perfectly healthy.
