[Genomic medicine for preconception, prenatal and postnatal diagnostics]

Area of Science:

• Genetics
• Bioethics
• Medical Diagnostics

Background:

• Advancements in genetic testing technology enhance diagnostic precision and enable personalized medical treatments.
• The identification of genetic variants with unknown disease associations or uncertain significance presents diagnostic challenges.
• Genetic knowledge is increasingly utilized across reproductive and pediatric contexts, including preconception, prenatal, and childhood diagnostics.

Purpose of the Study:

• To explore the dual impact of new genetic testing technologies on medical diagnostics and treatment.
• To examine the ethical considerations arising from the identification of genetic variants of unknown significance.
• To discuss the implications of genetic testing in preconception, prenatal, and childhood settings, particularly concerning late-onset disorders and individual autonomy.

Main Methods:

• Review of current genetic testing technologies and their applications.
• Analysis of diagnostic outcomes, including the identification of variants with uncertain significance.
• Ethical framework analysis concerning genetic information disclosure and its impact on future life choices.

Main Results:

• New genetic testing provides more accurate diagnoses and tailored therapies.
• Challenges arise from variants with unknown or uncertain clinical significance.
• Ethical dilemmas emerge, particularly regarding the right to an open future for children diagnosed with late-onset conditions.

Conclusions:

• Genetic testing advancements offer significant clinical benefits but necessitate careful interpretation of results.
• Ethical guidelines are crucial for navigating the complexities of genetic information, especially in pediatric cases.
• Balancing diagnostic utility with the protection of individual autonomy and the right to an open future is paramount.
