Study Population

Pregnant women carrying a fetus at risk or a confirmed fetus with 22q11.2 deletion/duplication. A person confirmed to have 22q11.2 deletion/duplication or a biologically related parent of a child that has chromosomal deletion/duplication in the region of 22q11.2.

Description

Inclusion Criteria:

  3. Patients must meet at least one of the following conditions at the time of enrollment:

    1. are pregnant with abnormal fetal cardiac findings on ultrasound and is undergoing evaluation with prenatal genetic testing or planned post-natal genetic testing in the immediate newborn period;
    2. are pregnant with fetal ultrasound findings consistent with a 22q11.2 deletion/duplication phenotype and is undergoing evaluation with prenatal genetic testing or planned post-natal genetic testing in the immediate newborn period;
    3. are pregnant with a fetus known to have a 22q11.2 deletion/duplication confirmed by genetic testing with documentation is available;
    4. are biologically related parent of an enrolled child has chromosomal deletion/duplication in the region of 22q11.2;
  4. If the site is selected to enroll control patients, they must be pregnant women undergoing prenatal genetic evaluation for 22q11.2 deletion/duplication.

Exclusion Criteria
