Parental origin of chromosomal nondisjunction in a 49,XXXXY male using recombinant-DNA techniques.

Abstract

We have analyzed the origin, in a patient with 49,XXXXY, of the four X-chromosomes by means of recombinant DNA techniques. We found a maternal origin of the four X-chromosomes due to non-disjunctions in the first and second meiotic divisions.
