[Prenatal diagnosis: uncertainties and perspectives].

Area of Science:

• Perinatology and Medical Genetics
• Reproductive Medicine

Context:

• The legal framework for fetal medicine was established in 1994, licensing specialized centers for prenatal diagnosis.
• Advancements in ultrasonography, genetics, and molecular biology have led to earlier and more sophisticated prenatal testing.
• Prenatal diagnosis presents clear indications for terminating pregnancies with severe malformations, but poses ethical challenges for conditions with uncertain outcomes.

Purpose:

• To review the evolution and implications of prenatal diagnosis.
• To discuss the ethical considerations surrounding prenatal screening, particularly for conditions like Down syndrome.
• To highlight the potential of fetal DNA testing in maternal serum as a future diagnostic tool.

Summary:

• Prenatal diagnosis has evolved significantly since 1994, driven by technological progress in imaging and molecular biology.
• While beneficial for identifying fetal abnormalities, widespread screening raises complex ethical questions regarding risk assessment and societal impact.
• Emerging fetal DNA testing from maternal serum promises to reduce the need for invasive procedures and offers an alternative to preimplantation diagnosis.

Impact:

• Fetal DNA testing in maternal serum is poised to revolutionize prenatal diagnostics by offering a non-invasive and accurate alternative.
• This technological shift could mitigate ethical dilemmas associated with invasive prenatal testing and improve patient care.
• The findings underscore the need for ongoing ethical discourse in reproductive medicine as technologies advance.
