All fetuses develop a measurable nuchal translucency at some point in the first trimester. Thickness of the translucency varies with gestational age: Peak thickness at 12-13 weeks (in 75% of fetuses). At 12-13 weeks the 50th percentile thickness = 1.7mm. At 12-13 weeks the 95th percentile thickness = 2.8mm.
