Abstract
Methods for prenatal screening for trisomy 21 employ examination of the fronto-maxillary facial (FMF) angle of a fetus. The methods may comprise obtaining a two or three dimensional image of a fetal face, measuring the FMFangle and/or FMFangle on the image, and comparing the measured FMFangle and/or FMFangle with an FMFangle and/or FMFangle characteristic of chromosomally normal fetuses. A measured FMFangle and/or FMFangle greater than the FMFangle and/or FMFangle characteristic of chromosomally normal fetuses provides an indication of an increased likelihood of the occurrence of trisomy 21 in the fetus.
