The Short Answer
I'm not sure anyone knows exactly why each genetic abnormality so commonly affect the face. It does seem that chromosomal problems almost always have extreme manifestation in the face as opposed to other areas (with exception perhaps of genitals). One SPECULATION I can give is that facial development continues well beyond most other types of development. Look at the chart here _URL_0_ Eyes, brain, teeth, and genitalia are some of the last things to develop. Often malformations in one area can affect subsequently developing areas. For instance cyclopia is a fetal problem where the eyes don't separate and form one giant one instead. This almost always also causes the nose to be on the forehead eyes instead of below the eyes since the nose should naturally migrate downwards. When the eyes are in the way, the nose can't migrate. One might imagine that things which develop last have the greatest chance of encountering multiple problems which affect their own development: sort of a buildup of anomalies.
