Three cases of minor chromosomal aberrations discovered by prenatal chromosome determination.
A case of pronounced secondary constriction of a chromosome belonging to pair N0. 9, a case of deletion of the short arms of one of the chromosomes in pair No. 13, and a case of partial trisomy of the distal portion of a chromosome in pair No. 14 were discovered by prenatal chromosome determination.  Analysis of the parents' karyotypes enabled the clinical importance of the three different chromosomal aberrations to be elucidated.
