A prenatally detected inv dup(15).
An extra G group-like chromosome was found in an amniotic fluid cell culture. With multiple banding techniques it was identified as inv dup(15). BUdR incorporation was used to determine the lateral asymmetry of the marker, which consisted of 2 distal spots arranged contralaterally, consistent with DNA polarity conservation in chromosome rearrangements.
