Current landscape of prenatal genetic screening and testing

Area of Science:

• Obstetrics and Gynecology
• Medical Genetics
• Fetal Medicine

Background:

• Prenatal genetic testing offers valuable insights into fetal health.
• The landscape of genetic screening and diagnostic testing is rapidly advancing.

Purpose of the Study:

• To review current prenatal screening and diagnostic testing options.
• To inform healthcare providers and patients about available genetic testing modalities.

Main Methods:

• Review of current literature and available prenatal genetic testing technologies.
• Categorization of screening and diagnostic tests based on methodology, accuracy, and indications.

Main Results:

• Prenatal screening identifies conditions such as aneuploidy, congenital abnormalities, and carrier status.
• Diagnostic testing includes karyotype, prenatal microarray, and next-generation sequencing.
• Testing options differ in accuracy, timing, and the information provided.

Conclusions:

• A range of prenatal genetic screening and diagnostic tests should be offered to pregnant patients.
• Test selection depends on patient-specific factors like age, family history, and preferences.
• The evolving nature of prenatal testing necessitates ongoing review of available modalities.
