SNP-based Microdeletion and Aneuploidy RegisTry (SMART)

Descriptive Information
Brief Title † SNP-based Microdeletion and Aneuploidy RegisTry (SMART)
Official Title † SNP-based Microdeletion and Aneuploidy RegisTry
Brief Summary This multi-center prospective observational study is designed to track birth outcomes and perinatal correlates to the Panorama prenatal screening test in the general population among ten thousand women who present clinically and elect Panorama microdeletion and aneuploidy screening as part of their routine care. The primary objective is to evaluate the performance of Single Nucleotide Polymorphism (SNP)-based Non Invasive Prenatal Testing (NIPT) for 22q11.2 microdeletion (DiGeorge syndrome) in this large cohort of pregnant women. This will be done by performing a review of perinatal medical records and obtaining biospecimens after birth to perform genetic diagnostic testing for 22q11.2 deletion. Results from the follow-up specimens will be compared to those obtained by the Panorama screening test to determine test performance. Specific test performance parameters will include: PPV, specificity, and sensitivity.
Detailed Description The primary objective is to determine in a prospective study the performance of SNP based NIPT for the 22q11.2 microdeletion (DiGeorge syndrome) in a large cohort of pregnant women clinically opting for this form of screening. Specific test performance parameters will include: positive predictive value (PPV), specificity, and sensitivity. Secondary objectives include: 1. Determine the test performance (PPV, specificity) of SNP based NIPT for detecting other microdeletion syndromes available in the Panorama microdeletion panel (e.g., 1p36 deletion, Cri-du-chat, Prader-Willi, and Angelman) individually and all combined (including 22q11.2). Given the incidences of
