A fetus with 68,XX karyotype was ascertained by an elevated midtrimester MSHCG. By antenatal ultrasound, the only unusual finding was in relation to the placenta. Preterm delivery was mandated by the development of severe preeclampsia. Postmortem examination of the stillborn fetus demonstrated no abnormal physical findings other than bilateral syndactyly of fingers and toes.
一名核型为68,XX的胎儿通过孕中期母血清人绒毛膜促性腺激素（MSHCG）升高得以确诊。产前超声检查发现唯一异常的是胎盘。因重度子痫前期的发展而进行了早产。对死产胎儿的尸检显示，除了手指和脚趾双侧并指（趾）外，没有其他异常体征。
