Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Natera sgNIPT is intended for use in pregnant people whose fetus/ fetuses are identified as at increased risk for a single gene disorder, such as one of the disorders below, when there is no reproductive partner (paternal) screening available or when there is positive reproductive partner screening, but prenatal diagnostic testing is not an option or when there is concern for a single-gene disorder in the fetus/ fetuses irrespective of carrier status (e.g., based on fetal ultrasound findings). Disorders include:

CF (CFTR) SMA (SMN1) Alpha-thalassemia (HBA1/HBA2) Beta-hemoglobinopathies including sickle cell disease (HBB)

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Age 18 or older at the time of informed consent
2. Maternal participant: Pregnant and blood draw at ≥ 9 weeks gestational age (GA)
3. Maternal participant is positive for a single-gene disorder and/or there are prenatal ultrasound findings suggestive for a fetal single-gene disorder, including but not limited to the genes listed in the primary and secondary objectives
4. Meet the criteria for one of the following:

* Both maternal and reproductive partner (paternal) status are positive for the same single-gene disorder OR
* A commercially available single-gene NIPT has been performed as part of clinical care and is reported as increased risk for an affected fetus/fetuses OR Maternal status is positive for one or more single-gene disorders and reproductive partner status is unknown OR
* Prenatal ultrasound findings are suggestive of a fetal single-gene disorder (autosomal dominant, autosomal recessive, or X-linked condition) and enrollment is approved by the medical monitor.
5. Willing to permit release of neonatal health information and the performance of a newborn cheek swab within 6 months following delivery
6. Willing to sign informed consent and comply with study procedures

Exclusion Criteria

1. Reproductive partner found to not be positive for the same autosomal recessive genetic disorder as the pregnant maternal carrier, or vice versa
2. Surrogate gestation or egg donor pregnancy
3. Negative preimplantation genetic testing for the single-gene disorder identified in one or both parents
