Triploidy 69, XXX in a stillborn girl

Abstract

Complete triploidy was found in lymphocyte cultures From a stillborn full‐term female infant with a birthweight of 1,000 g. The child had B ventricular septal detect of the heart hut no other macroscopic internal or external malformations. The mother, who had a history of prolonged anti‐asthmatic medication, displayed a high incidence of satellite associations and chromatid breakages in her cultured lymphocytes. The possibility that such changes are instrumental in the formation of triploid zygotes is discussed.
