| Abstract |
A 3 month-old boy with a karyotype of 48, XYY, + 21 is reported. The patient had the typical features of Down syndrome and normal male genitalia.
Analysis of Q- and R-banded chromosome heteromorphisms of the patient and the parents showed that two of the three chromosomes 21 in the patient originated as a result of failure of the paternal second meiotic division. Therefore both additional chromosomes in the patient resulted from nondisjunction at paternal meiosis II. |
