Abstract:
We report 2 cases of 47,XXX that were diagnosed prenatally and were screened positive for trisomy 21 by biochemical and ultrasound markers. These cases underline the importance of discussing the sex chromosome abnormalities during the genetic counseling after an abnormal triple screen test or ultrasound examination.
