We report on a 22 year old mother, a carrier of a 6;14 balanced reciprocal translocation, who aborted a triploid conceptus carrying a similar translocation. We showed the maternal origin of this triploidy, after non-disjunction at meiosis I. The phenotypic expression as a non-molar pregnancy, the contribution of the maternal translocation, and possible aetiological factors of triploidy are discussed.
我们报告了一位22岁的母亲,她是6;14平衡易位携带者,其流产的三倍体胎儿也携带类似的易位。我们证实了该三倍体源自母亲,是减数分裂I期不分离所致。本文讨论了该三倍体表现为非葡萄胎妊娠的表型、母亲易位的作用以及三倍体可能的病因。
