Certain features detected during a second trimester ultrasound exam are potential markers for Downs syndrome and they include dilated. However only 168 of the Downsyndrome cohort had an MNM angle below the 5 th centile and 42 had a positive FP line. Absent or shortened nasal bone this marker has a stronger link with Down Syndrome than most others One soft marker that might have shown up on the first-trimester NT screening which is always performed between weeks 10 and 13 is nuchal-fold thickening where the area at the back of a babys neck accumulates fluid causing it to appear thicker than usual.
