Prenatal Diagnostic Value of Chromosomal Microarray in Fetuses with Nuchal Translucency Greater than 2.5 mm

Figure 1

Flowchart of patient characteristics and chromosomal findings from quantitative fluorescent polymerase chain reaction (QF-PCR) and chromosomal microarray (CMA) of 499 amniotic fluid and chorionic villus samples from pregnancies with an nuchal translucency (NT) ≥2.5 mm. CNVs, copy number variants; VOUS, variants of uncertain significance.
