近年来,关于人类染色体的异形性(正常变异)或称异态的染色体区,亦即染色体多态的研究已被重视。关于它和人类疾病以及病理性妊娠、胎儿畸形、不孕症的关系也进行了一些探讨。我们对一对多次自发流产夫妇作了遗传咨询。经外周血淋巴细胞培养及G与R显带分析染色体,确认男方核型46,XY;女方核型46,Xx,14p~+。再经银染法处理标本证实女方14号染色 In recent years, studies have focused on chromosomal regions, ie, chromosomal polymorphisms, concerning the abnormality (normal variation) or abnormalities of human chromosomes. About it and human disease and pathological pregnancy, fetal malformations, infertility also made some discussion. We conducted a genetic counseling on couples who spontaneously aborted several times. Chromosomes were analyzed by peripheral blood lymphocyte culture and G and R bands to confirm the karyotype of male 46, XY and the female karyotype 46, Xx, 14p ~ +. Silver staining and then treated specimens confirmed that the woman on the 14th stain
