Abstract
Down’s syndrome patients have an extra G chromosome in all their cells, whereas the trisomy G/normal mosaic patients have this extra chromosome only in some of their cells. For this reason, a direct relationship between any measurable sign of Down’s syndrome and the extra G chromosome could be expected to result in an occurrence of that sign in mosaic patients in a degree proportional to the percentage of trisomic cells, while non-measurable clinical signs would only appear in a percentage of mosaic patients.
