SNP-based Microdeletion and Aneuploidy RegisTry (SMART)

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 ...

Phase N/A

Whole Blood Specimen Collection From Pregnant Subjects

This sample collection protocol allows for the identification, recruitment, and participation in women who are pregnant and are known to: 1. be at an increased risk for fetal genetic abnormalities 2. be at increased risk for congenital fetal infection by virtue of being positive by initial screening tests, or are ...

Eligible subjects will provide written informed consent after which basic demographic and clinical data will be collected. Study procedures involve the collection of 50 mL of whole blood at one or more monthly clinic visits (≥25 days apart) from pregnant women (18 to 54 yrs of age) carrying a single ...

Phase N/A

Resistance to Vitamin D or Parathyroid Hormone

Patients with confirmed or suspected states with resistance to vitamin D or parathyroid hormone (PTH) will be admitted for diagnosis and treatment and for inclusion in other protocols. These states include hypocalcemia, rickets, osteomalacia, pseudohypoparathyroidism. Resistance to a factor is manifested by deficient bioeffect despite high levels of the factor ...

Phase N/A

Studies of Elevated Parathyroid Activity

Patients with confirmed or suspected primary hyperparathyroidism or complications therefrom (such as postoperative hypoparathyroidism) will be admitted for diagnosis and treatment. The principal diagnostic components are calcium in serum and urine and parathyroid hormone in serum. Patients with moderately to highly severe primary hyperparathyroidism will be treated.
