Chromosome abnormality in couples with histories of multiple abortions. The outcome of pregnancies subsequent to ascertainment and a study of familial translocation carriers.
A series of couples with histories of recurrent abortions and in whom one partner had been shown to have a major chromosomal anomaly were investigated with respect to the karyotypes of conceptions subsequent to ascertainment. The reproductive histories of translocation carriers amongst relatives were also studied. Results were compatible with previous reports of the behaviour of translocation chromosomes at meiosis with an additional previously undescribed outcome as a result of a maternal 13/14 Robertsonian translocation.
