Abstract

The first known case of trisomy 20 mosaicism is described. As in other cases of (partial) trisomy 20, the patient showed scarce physical malformations. It is suggested that trisomies for chromosomes of the F group are rare not because they are lethal but as a result of the morphology of the chromosomes involved.
