EXpanding Prenatal Cell Free DNA Screening Across moNogenic Disorders (EXPAND)

The purpose of this research is to develop and validate a single gene Non-Invasive Prenatal Test. The development of this investigational single-gene noninvasive prenatal testing (sgNIPT) for conditions such as cystic fibrosis (CF), spinal muscular atrophy (SMA), Sickle cell disease, alpha thalassemia (a-thalassemia) and beta thalassemia (b-thalassemia) could provide information about the possibility that a child will be born with a serious health condition, in some cases in the absence of reproductive partner screening.

In order to develop a test for this purpose, investigators will collect blood samples and medical information from pregnant women who have pregnancies at higher risk for single gene disorders, such as those who are carriers for these conditions or affected by these conditions themselves, medical data from their reproductive partners in some cases, and either genetic testing results or a cheek swab sample from the newborn(s).
