Amniocentesis and prenatal chromosome analysis were performed for advanced maternal age. The fetus was male with a paracentric inversion in the long arm of the X chromosome. The mother and a brother also carried the inversion. The pregnancy continued to term and the infant is developing normally at one year of age.
因孕妇年龄较大,进行了羊膜穿刺术和产前染色体分析。胎儿为男性,X染色体长臂存在着丝粒旁倒位。母亲和一个兄弟也携带这种倒位。妊娠足月,婴儿一岁时发育正常。
