In utero diagnosis has undergone an amazing revolution in recent years. More tests are available; the indications for prenatal diagnosis have expanded - you can now advise your patients about disorders you could not have previously detected. Medical training for obstetricians, medical geneticists, and genetic counselors has not kept pace with these developments. Clinical exposure to common and unusual problems in prenatal diagnosis is limited.

Prenatal Diagnosis: Clinical Cases and Challenges, based on the authors’ several decades of experiences, fills this gap. Real cases portray diagnostic problems as a route to the underlying biology, the available testing options, and the results that might be obtained. The authors discuss the challenges of management, interpretation, and counseling.

Cases used throughout emphasize three types of clinical problems:

• Chromosomal abnormalities
• Mendelian disorders
• Fetal structural abnormalities

The decision to enter the world of prenatal diagnosis should be very carefully considered by any prospective mother. Prenatal Diagnosis: Clinical Cases and Challenges will help you discuss the issues in an informed manner with your patients.
