In brief: Chromosome influence

The size & shape of the skull & facial features of down syndrome patients is heavily influenced bu the effect of the extra chromosome present in every cell of the body.
The same goes for eyes, hands & feet all of which require a lot of decoding during formation to produce the structures. Many other chromosome defects produce some common features to those born with the abnormality.
